What’s New in Superna Eyeglass PowerScale Edition Release 2.5.6

T10935 Pool failover "failovertarget" must be "zone id"

The "failovertarget" field must be "zone id" even though description indicates "ID of the access zone OR syncIQ policy to failover".

Workaround: Enter "zone id" for "failovertarget" when initiating pool failover.

—————————————————–

T7622 Eyeglass will not add custom SPNs if PowerScale Cluster does not return any missing SPN during SPN check (as of 2.5.6)

As of 2.5.6 Eyeglass can manage custom SPN creation based on Eyeglass configuration - additional information available . If PowerScale does not identify any missing SPNs Eyeglass Configuration Replication will not insert custom SPNs. If PowerScale identifies any missing SPN, Eyeglass will insert all custom SPN even if PowerScale does not identify it as missing.

Workaround: SPNs to be added manually if required. For failover, no additional steps - failover will manage all SPN updates based on custom SPN definition.

—————————————————–

T13360 Failover Readiness Validation for Corrupt Failover Snapshots does not check for missing snapshot

There must be one failover snapshot on the target cluster per SyncIQ policy being failed over. The Corrupt Failover Snapshots validation does not check whether that snapshot is missing. Impact: Allow Writes step of failover will fail.

Workaround: Verify presence of snapshot manually on target cluster

isi snapshot snapshots list | grep <SyncIQ Policy Name>

Replacing SyncIQ Policy Name iwth your our SyncIQ Policy Name

example for expected configuration

isi snapshot snapshots list | grep policy1

—————————————————–

T12434 Concurrent Access Zone or Pool Failover with DFS configured policies may fail DFS share rename step

When doing concurrent Access Zone or Pool Failover where the Access Zone or Pool have associated jobs in Eyeglass DFS mode the share renaming step may happen in parallel and depending on the OneFS release an PowerScale OneFS API defect may incorrectly handle the request causing the share rename to be in error.

Workaround: Verify with Dell EMC support whether your OneFS version has this issue. For any shares where share renaming fails they will have to renamed manually - the failover log will indicate which failed and which succeed.

—————————————————–

T13701 Failover option "Disable SyncIQ Jobs on Failover Target" does not reapply schedule

When the failover option Disable SyncIQ Jobs on Failover Target" is selected the synciq policy schedule is not reapplied to the active synciq policy on the target cluster.

Workaround: The original SyncIQ policy schedule is captured in the failover log. Reapply the schedule to the policy manually on the PowerScale. 

—————————————————–

T13726 Pool Failover error mapping policy to pool on target cluster for disabled job

If Pool Failover is initiated and there is an associated Eyeglass Configuration Replication job that is disabled, the failover correctly skips failover of the associated synciq policy / data but incorrectly attempts to associate the mirror policy to a pool on the target cluster resulting in an error for the step "Transfer pool mapping" with mesage "Could not find policy ....".

Workaround: None required failover has been completed successfully for policies which were enabled. No impact to failback.

————————————

T13881 Cannot failover overlapping Access Zones - rel 2.5.6

In Release 2.5.6 overlapping Access Zones cannot be failed over. The network updates that are done durinig failover are rolled back.

Workaround: Use Release 2.5.5 to failover overlapping access zones

————————————

T14398 Zone/Pool Failover Readiness FQDN Alias validation incorrectly reports OK when pool does not have an ignore hint

For case where PowerScale cluster has been provisioned in Eyeglass using FQDN, that FQDN should not be failed over during Zone or Pool failover - it needs to remain associated with its current cluster. This is achieved by configuring the associated IP pool to be "ignored" during failover. The validation that checks whether this configuration is in place incorrectly indicates OK when the "ignore" is not configured.

Note that as of Eyeglass 2.5.3 and higher clusters no longer being added to Eyeglass using FQDN due to PowerScale CSRF not compatible with Smartconnect and API services.

Workaround : If cluster still added to Eyeglass using FQDN modify to be added using IP. Please following Technical Advisory #17 and Technical Advisory #22.

————————————

T14931 Policies configured for Pool failover allowed to do DFS or SyncIQ failover until next configuration replication runs

Policies configured for pool failover are blocked from being failed over in DFS or SyncIQ mode except for period of time between when pool to policy mapping for Pool Failover has been completed and next Configuration Replication cycle has completed.

Workaround: None required - Do not initiate DFS or SyncIQ mode failover for policies configured for pool failover. Next schedule Configuration Replication job will rectify and after that point the DFS and SyncIQ failover mode will not be available for policies configured for Pool Failover.

—————————————————

T14948 Failover log for Uncontrolled Access Zone incorrectly logs status of final readiness job and changes to pool aliases

The failover log for an uncontrolled Access Zone failover will incorrectly report the status of the final failover readiness step as SUCCESS instead of error and will incorrectly summarize the Pool aliases on source after failover and Pool aliases on destination after failover at the end of the log.

Workaround: None required, this is a logging issue only. The failover correctly logs client redirection steps in the Networking updates section of the log which records the changes as they are being executed. The failover readiness status can be viewed on the DR Dashboard / Zone Readiness.

—————————————————

T14965 Failover readinessSyncIQ File Pattern Validation has WARNING state instead of ERROR

Failover readiness SyncIQ File Pattern Validation which detects that SyncIQ policy has file patterns should be ERROR instead of WARNING as PowerScale OneFS Resync Prep function that prepares you for failback will fail when SyncIQ is configured this way.

Workaround: This setting should not be used for DR purposes.

—————————————————

T14971 DR Assistant validation check screen incorrectly requests acknowledgement of readiness warnings

For case where DR Failover status is OK or Info, the DR Assistant Failover wizard validation check step requests acknowledgement that warnings have been reviewed even though DR failover status has no warning status.

Workaround: Close the DR Assistant window and open the DR Dashboard window and confirm that indeed failover status has no Warning states. If so, start the failover again and now select the "I have reviewed the warning status" check box and continue with the failover.

—————————————————

T14974 Access Zone Failover with error on DFS share renaming will abort for all policies

For the case where an Access Zone hss both DFS and non-DFS configured jobs in Eyeglass, if share renaming fails for all shares associated with a DFS policy Client redirection will be considered an error for non-DFS policies as well and failover will be aborted instead of continuing for non-DFS configured jobs.

Workaround: Share renaming issue should be resolved before re-attempting the failover.

—————————————————

T14988 Eyeglass GUI incorrectly allows pool failover configuration for a policy that is active in failover rehearsal mode

From the Eyeglass DR Dashboard you are allowed to map a policy for pool failover when it is in active rehearsal mode even though you cannot initiate a failover when it is in this state.

Workaround: Review policy status and confirm not in rehearsal mode before configuring pool failover.

—————————————————

T15000 DR Rehearsal status lost if fingerprint file deleted

A fingerprint file is used to persist DR Rehearsal status. If the fingerprint file is deleted or otherwise removed while rehearsal mode is active, rehearsal status is lost and there is no way to revert rehearsal mode.

Workaround: Please contact support at support.superna.net to recover from this state.

—————————————————

T15042 REST API policy readiness is missing output for Target Reachability check

The SyncIQ policy readiness retrieved using REST API is missing the output for the Target Reachability check. If the Target Reachability validation fails, the overall Failover Status is correctly in ERROR and failover cannot be initiated

Workaround:

• To assess target reachability:
  • Target reachability alarms related to Inventory or Configuration replication would have been sent.
  • From the Eyeglass web interface, Eyeglass / PowerScale reachability can be viewed from the Continuous Operation Dashboard.
• All failover readiness criteria can be viewed from the Eyeglass web interface DR Dashboard.

—————————————————

T15010 DR Rehearsal Revert not blocked for Pool Failover mode when in REHEARSAL_ERROR

If after enabling DR Rehearsal mode for Pool Failover the DR failover status is REHEARSAL_ERROR the failover wizard incorrectly allows you to initiate a revert for rehearsal mode.

Workaround: To recover from this REHEARSAL_ERROR open a support ticket at support.superna.net for assistance. 

————————————

T15609 Alarm time not upated for repeated policy/dfs/zone/ pool readiness alarms

If a policy, dfs, zone or pool readiness alarm occurs multiple times, the Alarm time will not be updated with each occurrence. It will display only the first time the alarm is raised. Email notification also only sent on initial occurence of the alarm. Subsequent occurences will not send an email.

Workaround: Open the DR Dashboard to see the current state of the validations as of the last time the Zone/Pool Readiness job has run.

—————————————————

T15191 Failover Log may show 2 summaries when Rehearsal Mode enabled

When Rehearsal Mode is enabled for an Access which has DFS policies or enabled with multiple pools which also have DFS, the failover log summary shows an interim summary after data access steps and a final summary at end.

Workaround: None required - summary has required information.

————————————

T15192 Rehearsal Mode not disabled for Access Zone assoicated with Pool Failover

From the DR Dashboard, the Access Zone associated with a Pool Failover already active in Rehearsal Mode can be selected for enabling Access zone Rehearsal Mode again even though this is not a valid configuration for Rehearsal Mode.

Workaround: None Required, the next window in DR Assistant identifies the invalid configuration and correctly blocks Rehearsal Mode enabling for the Access Zone.

————————————

T15248 Error in DFS failover does not rollback share renaming when failover job includes multiple policies

A DFS failover which contains multiple policies will not rollback share renaming for a policy that encounters an error if the remaining policies succeed.

Workaround: Use PowerScale interface to remove and add igls-dfs prefix for affected shares.

————————————

T15260 DFS Failover share renaming rollback not done when all share rename fails on source cluster

If client redirection step of failover which adds igls-dfs prefix to shares on the source cluster fails for all of the shares associated with the source cluster the failover stops but the share renaming that completed successfully for the target cluster is not rolled back.

Workaround: Use PowerScale interface to add igls-dfs prefix to shares on the target cluster.

————————————

T15271 Zone/Pool Failover error in SMB Data Integrity step or run policy step incorrectly attempts to roll back networking

If the inital share lockout for SMB Data Integrity step fails or run policy step fails, the failover is aborted as expected but then steps are executed to roll back networking changes even though none were made. There is no impact other than error in failover log as these commands fail as they are attempting to update to configuration that already exists on the cluster.

Workaround: None required - the commands executed do not result in any changes on the PowerScale cluster.

————————————

T15278 Pool Failover job with multiple pools stops failover steps for all pools on DFS share renaming error

If an error which will abort failover occurs for DFS share renaming on one pool where the failover job contains multiple pools, failover will be aborted for all pools instead of continuing for pool which has no error.

Workaround: When failing over multiple pools, execute concurrent failover with 1 pool per failover job.

————————————

T15290 Pool Failover job with multiple pools does not rollback client redirection when allow writes step fails

If an error occurs on allow writes for one pool in a failover job that contains multiple pools there is no rollback for networking for failed pool.

Workaround: Networking can be failed back manually using PowerScale interface and using Failover log as as a guide. Also can failover multiple pools concurrently with 1 pool at a time.

————————————

T15298 Quota job run manually after failover may delete quotas on source cluster

Even if quota failover steps fail on failover from cluster A to cluster B such that no quotas are created on cluster B and all quotas exist on cluster A, the quota failover job from cluster B -> A is created and enabled. If this Quota job is run manually it will delete all related quotas on the source (cluster A) leaving you without related quotas on source or target.

Workaround: Do not run quota jobs manually. Contact support.superna.net for assistance to failover quotas that failed during failover.

————————————

T15530 Policy or DFS Readiness may incorrectly evaluate Policy Hostname validation in error

DR Dashboard / DR Assistant Policy Readiness or DFS Readiness may incorrectly evaluate Policy Hostname validation in Error state placing overall failover status in Error. This validation should only be being assessed for Access Zone or Pool failover.

Workaround: Follow steps for Access zone failover configuration to ignore failover for the pool that has the Target Host. Steps to do this are on the target cluster apply "igsl-ignore" hint on the pool which has the SyncIQ Policy Target Host. Ignore hints are simply an alias with the name of "igls-ignore". Note it is best practise to ensure unique hints by using a naming format that uses cluster name - for example: igls-ignore-<clustername>. Documentation reference can be found - see section on ignore hints.

Once configured run the Eyeglass Configuration Replication Job to update DR Dashboard / DR Assistant.

————————————

T15547 Failover Readiness Domain Mark Validation fails for path with spaces or special characters

The Failover Readiness Domain Mark Validation returns an error for SyncIQ policy source path that has a space or contains special characters.

Workaround: Manually confirm presence of domain mark by running command on PowerScale: isi_classic domain list . DR Failover Status of Warning does not block failover. For additional information on readiness validations in Warning state please refer to our documentation or contact support.superna.net.

————————————

T15610 Policy Readiness Pool Mapping Validation alarm and email indicate Warning severity instead of Error

For the cases where an Access Zone is configured for Pool Failover and there are policies which are not mapped to pools the Un-Mapped Policy SmartConnect/IP Pool Status alarm and email incorrectly indicate that this is a Warning level issue. The DR Dashboard correctly identifies the issue as an Error which would block initiating a failover.

Workaround: Review readiness from the DR Dashboard directly.

————————————

T15613 DR Rehearsal Readiness - no alarm or email when DR Rehearsal status changes from OK to Warning or Error

No Alarm is raised or email sent when DR Rehearsal readiness status changes from OK to Warning or Error status.

Workaround: Login to the Eyeglass GUI and open the DR Dashboard to review readiness.

————————————

T15623 REST API - Pool Failover API does not support multiple pool selection

From Eyeglass DR Assistant a Pool failover can be initiated for multiple pools but this is not supported from the API.

Workaround: Run concurrent failover for multiple pools.

————————————

T15624 REST API - Failover API does not block controlled failover when source cluster unreachable

Failover API does not validate source cluster reachability and will allow a controlled failover to start even if source cluster unreachable. Controlled failover in this case is expected to fail as it will attempt steps against the source cluster. When source cluster is not reachable uncontrolled failover should be used.

Workaround: Use manual process to verify source cluster reachability and initiate the appropriate controlled or uncontrolled failover.

————————————

T15769 DNS Dual Delegation Validation does not work where NS Record does not resolve directly to an SSIP

If DNS Dual Delegation is configured with NS Records that resolve to a name (for example configured as CNAME) the DNS Dual Delegation Validation will not work as it is expecting an IP address on resolution of the NS Record.

Workaround: To avoid this warning DNS Dual Delegation validation can be disabled. Please contact support.superna.net for assistance.

————————————

T16154 DR Rehearsal mode has invalid readiness validation for Corrupt Failover Snapshots

For case where SyncIQ Policy involved in DR Rehearsal mode enabled has different source and target paths or space in SyncIQ Policy path or a special character in SyncIQ Policy path, after DR Rehearsal mode enable the DR Failover Status incorrectly shows an Error for Corrupt Failover Snapshots for that policy. This error blocks reverting DR Rehearsal mode.

Workaround: Do not use DR Rehearsal mode for policies which have different source and target paths, spaces in paths or special characters in paths. Regular failover is unaffected by this issue and is available. To recover from this REHEARSAL_ERROR open a support ticket at support.superna.net for assistance. 

————————————

T17136 Zone Readiness incorrectly shows Error when Access Zone Name, Smartconnect Zone Name and IP Pool name are exactly the same

DR Dashboard Zone Readiness incorrectly shows Policy Readiness Status, SmartConnect/IP Pool Settings and Mappings Readiness and Eyeglass Failover Mapping Hints in error when the Access Zone, SmartConnect Zone Name, IP Pool all have exactly the same name.

Workaround: This issue can be resolved by renaming the Access Zone to be different. This change should be assessed for impact in your environment before making this change.

————————————

T17401 Pool Readiness not displayed with no configured/reachable DNS

If both Eyeglass and Isilon DNS are not available, the DR Dashboard pool readiness is not displayed.

Workaround: Provide reachable Eyeglass or Isilon DNS.

————————————

T17477 DFS share suffix not applied for failover or configuration replication

If a custom suffix is configured for DFS share name on target cluster, suffix is not applied either during configuration replication or during share renaming step of failover.

Workaround: None available.

————————————

T17428 REST API - Policy Readiness returns incorrect Access Zone

Failover API to retrieve Policy Readiness information returns the incorrect Access Zone for environments with multiple Access Zones.

Workaround: None required. Access Zone does not affect Policy Failover and Access Zone Readiness and Failover correctly assign policy to correct Access Zone.

————————————

T17447 OneFS 9.0 and 9.1 Readiness Validation for Policy Source Nodes Restriction always shows INFO

For OneFS 9.0 and 9.1 even if the Policy Source Nodes Restriction is configured, the Readiness Validation always shows INFO,

Workaround: Verify on PowerScale the source nodes restriction settings. DR Status of INFO does not affect / block ability to failover.

————————————

T17522 Failover Scripting Engine SOURCE and TARGET variables expose password

The Failover Scripting Engine SOURCE and TARGET environment variable information includes the password of the account used to connect from Eyeglass to PowerScale in plain text.

Workaround: Do not use these variables in scripting.

————————————

T17555 Blank display for Zone or Pool Readiness

In some instances where Zone and Pool failover is configured the Zone or Pool readiness window may be blank when both the DR Assistant and DR Dashboard are open.

Workaround: Reload the tab or only have one window open at a time.

————————————

T17731 Policies missing in DR Assistant for Zone or Pool failover

DR Assistant missing policies in an Access Zone for Zone or Pool failover where there are no SMB shares or NFS exports configured at or below the SyncIQ policy source path. Impact is that failover steps are not executed against these policies and they remain active on the source cluster.

Workaround: In advance of failover, configure a temporary share with restricted permissions at the SyncIQ policy source path. If you have failed and only then determine the issue, policies can be failed over using Policy failover if the failover was an Access Zone failover. If the failover was a Pool failover manual steps must be used to failover the remaining policies.

————————————

T17732 Multiple Zone Readiness Jobs

Under some circumstances multiple Zone Readiness jobs will be running at the same time without any completing. DR Dashboard not updated when in this state. If this occurs during Access Zone failover it does not block failover.

Workaround: Eyeglass sca service restart will address this issue but recommend to contact support.superna.net for assistance and evaluation of the issue.

————————————

T18127 DNS Dual Delegation uses wrong SSIP when IP Pool Service Subnet different from the pool subnet

The IP Pool Service Subnet setting that is different than the parent subnet of the IP Pool is not taken into account for the DNS Dual Delegation validation. This could result in incorrect assessment of the DNS delegation configuration or if no SSIP configured in the parente subnet can result in the error "This IP address does not reference valid cluster".

Workaround: Manual inspection of DNS NS Record delegation should be done to confirm that it has been configured correctly.

————————————

T18253 DR Rehearsal Mode Enable / Revert Error when multiple policies selected

A DR Rehearsal Mode Enable / Revert where more than 3 SyncIQ policies are involved either selected for SyncIQ or DFS mode or an Access Zone with more than 3 SyncIQ policies, the final step which updates Eyeglass with the rehearsal status fails with a lock conflict error..

Workaround: For SyncIQ or DFS Mode Rehearsal Enable or Revert do not select more than 3 policies at a time. For Access Zone Rehearsal mode where Access Zone has more than 3 SyncIQ policies run the Rehearsal exercise as a SyncIQ policy Rehearsal selecting a maximum of 3 policies at a time.

————————————

T18779 Overlapping Powerscale cluster and SyncIQ Policy names can result in incorrect Failover Readiness assessment

For the case where source and target Powerscale cluster have overlapping names (for example "cluster1" and "cluster1dr" ) and there are SyncIQ policies on both cluster with the same name, failover readiness for source cluster may take into account the SyncIQ policy state on the target cluster resulting in an incorrect state for source cluster. For example a SyncIQ policy disabled on the target cluster incorrectly results in Policy Enabling Readiness Warning for the SyncIQ policy on the source cluster.

Workaround: Rename the SyncIQ policy on the target cluster to make it unique between both clusters. For example pre-pend the SyncIQ policy name with the target cluster name.

Configuration Replication

1683: Export sync where source  is 7.1.1.x and target 8.x.x.x

Description: Syncing exports does not function between these releases.  

Resolution:  None unsupported sync, upgrade to 7.2.x.x

————————————————--

649: Export sync where source and target path on each cluster is different is deleted and recreated in each config cycle (affects onefs 7 to 8 or 8 to 7 replication)

Description: When the path on source cluster and target of the SyncIQ policy are different, exports will be deleted on target and then recreated again  within the same replication job. No error is seen on the config sync job. May affect other releases as well.

Resolution:  None, export is created correctly after config sync job completes.

————————————————--

1462 - Export max_file_size cannot be replicated

Updated export max_file_size parameter is not replicated and replication Job fails.

———————————-

1355: Edit Job configuration to include share/export deselected from another Job causes share/export to be reselected.

Description: When you edit a Job B configuration to include share/export that had already been deselected from Job A, this causes this share/export to be reselected for Job A as well.  

Workaround: None available.  Should the share/export subsequently be deselected from Job B it should then also be manually deselected again from Job A.

—————————————————–

1580: Delete and Create export within same replication cycle orphans deleted export on the target with OneFS 7.1.1.x

With OneFS 7.1.1.x, a delete and create export operation which occurs within the same replication cycle will replicate the export that was created on the next replication cycle but the export deleted on the source will not be deleted on the target.  

Workaround: Manually remove the deleted export from the target using PowerScale OneFS.

—————————————————–

1625: Custom QUOTA Jobs require extra replication cycle to be deleted

In the Eyeglass Jobs window, when you delete a CUSTOM Job and then the associated QUOTA Job is not immediately deleted.  It is deleted on the next replication cycle.

Workaround: None required.

—————————————————–

1639: Able to manually Run Now disabled Custom Job

Eyeglass Jobs window allows you to Run Now on a Custom Job which has been disabled.  A message is displayed indicating that the Job has been queued but the share/export configuration replication Job is not run and the associated QUOTA Job is run and quotas are replicated.

Workaround: Do not Run Now for Custom Job that has been Disabled.

—————————————————–

1641: Custom Job does not include shares/export when source or destination path configured with a trailing /

If you enter source or destination path for Eyeglass Custom Job with a trailing / (for example /ifs/data/test/ ), the Custom Job will not pick up the related shares and exports.

Workaround: Source and destination paths must be entered without the trailing / - for example /ifs/data/test.

—————————————————–

1788: Delete of unlinked user quota on source may not delete matching quota on the target

Attempting a quota replication after deleting an unlinked user quota may fail to delete the quota on the target with a Job status of success but an Audit failure.

Workaround: Deleted quota manually deleted on the target.

—————————————————–

1789: Able to select shares/exports/quotas outside job path after deselected

After a share/export/quota has been deselected from an Eyeglass Job, it can be re-selected for a different Job even if it is outside the Job path.  As a result, the Job may have an error for these share/export/quota due to path not found error.

Workaround: Do not customize Eyeglass configuration replication Job and select share/export/quota that are outside the Job path.

—————————————————–

1887, T3727: Multiple SyncIQ policies associated with same Zone will result in transient error on Eyeglass Zone replication creation

Where there are multiple SyncIQ policies which are associated to the same zone and Eyeglass configuration replication is being used to create the zone on the target, the first Zone replication job will succeed, but subsequent Zone replication jobs for the same Zone will fail with the message “Zone ‘<zone name>’ already exists”.

Workaround: None required for OneFS 7.2 - 7.2 or 8 - 8 replication.  Error will be cleared on subsequent configuration replication cycle.

For OneFS 7.2 - 8 replication, Zone Replication Readiness always has warning status and alarm is raised for failed audit on zone job.  Manually inspect that Access Zones are identical and that Zone Readiness Warning is related to this issue.

—————————————————–

1924: Quotas on excluded SyncIQ directory are selected for replication

Eyeglass quota job includes quotas related to excluded SyncIQ directories.  If quota job is run, it will typically fail due to path not found.

Workaround: Customize Quota Job and deselect quotas for excluded directories.

—————————————————–

1998: Custom Eyeglass configuration replication Job does not have an associated Zone replication Job

When you create a new custom Eyeglass Job, an associated Zone replication Job is not created.

Workaround: Zone must be created manually or already exist on the target cluster in order for Eyeglass configuration replication to succeed.

—————————————————–

2004: Custom Quota Job is incorrectly listed in the Failover: Quota Failover (RUN MANUALLY) section in the Jobs window

When you create a new custom Eyeglass Job, the associated Quota replication Job is created and incorrectly listed under Failover: Quota Failover (RUN MANUALLY) section in the Jobs window.  Custom Quota Jobs do not need to be run manually, they are run automatically each time the customer Eyeglass configuration replication Job is run.

Workaround: None required.  Custom Quota Jobs do not need to be run manually, they are run automatically each time the customer Eyeglass configuration replication Job is run.

—————————————————–

2007: Job error after deleting quota

After running Quota Job and successfully replicating quota to target, if quota is deleted and Quota Job is run again the Quota is successfully deleted from the target but the Quota Job has Error status.

Workaround: None required - quota is deleted.

—————————————————–

2038: Create alias results in temporary error

When an nfs alias is replicated to the target, the initial create leaves Job in Error state with  related alarm " Alias <alias name> already exists on this zone"

Workaround: None required.  Next replication cycle clears the error.

—————————————————–

2043: Configuration replication job has error after zone is deleted

For the case where Zone related to a Configuration Replication Job is deleted on the source, the Zone and associated configuration items are successfully deleted on the target, but the Configuration Replication job remains in Error state.

Workaround: None required.  Shares and exports are deleted as expected.

—————————————————–

2045: Edit Configuration for Custom Job has multiple source cluster selected where Eyeglass is managing more than 2 clusters

For the case where Eyeglass is managing more than 2 clusters, it may occur that the Edit Configuration view incorrect.

Workaround: None required.  Shares and exports are replicated as expected.

—————————————————–

2046: Job Edit Configuration view has the wrong parent selected

For the case where a configuration replication job contained a configuration items and the last configuration item is deleted - after the configuration item is deleted, the parent in the Edit Configuration view continues to be selected for the Job even though when you expand the tree there are correctly no children selected.

Workaround: None required.

—————————————————–

2049: Delete Zone does not delete associated configuration items on target for custom Jobs and auto jobs with disabled zone Job

When a non System zone is deleted on the Source, the Eyeglass Configuration Replication Custom Job or Auto job with disabled Zone Job does not remove the associated configuration items from target related to the deleted Zone.

Workaround: Manually delete the Zone and associated configuration items on the target using OneFS.

—————————————————–

2235: Eyeglass replication Job does not complete when source cluster becomes unreachable after Job has started

If the source cluster becomes unreachable after the Eyeglass configuration replication Job has started, the Job does not complete.

Workaround: None required.  The Job will eventually complete after all communications timeouts have occurred.  This may take an hour.

—————————————————–

2060: Access Zone Replication Error - Error on creation of shared resource

Error on Replication for Access Zone which shows Error on creation of shared resource.

Workaround: None required.  Once SyncIQ Job has run again in OneFS, the next time configuration replication runs the Access Zone is replicated.

—————————————————–

2488: Inconsistent behaviour in Run Now for Disabled Jobs

When Run Now is selected for an Eyeglass Job which is disabled, the handling is different depending on Job Type and state:

For Job which is “Policy Disabled” - Run Now is blocked for all Jobs

For Job which is “User Disabled” - Run Now not blocked and all enabled Jobs run

For Robot Job which is disabled - Run Now not blocked, Job is initiated and then fails.

Workaround: Only select enabled Jobs for Run Now.  

—————————————————–

1938: Issues with Eyeglass Configuration Replication Jobs after the Access Zone is deleted

When you delete an Access Zone in OneFS, the following issues occur in Eyeglass:

• corresponding Eyeglass Zone Configuration Replication Job is not deleted

Workaround: None Required.  Job is empty.

—————————————————–

2308: In EyeGlass, NFS alias health is always 'unknown'

Eyeglass Inventory, NFS Alias audit and Cluster Configuration Report always have the NFS alias health property set to unknown.

Workaround: Determine the NFS Alias healt from the OneFS command line using isi command..

—————————————————–

2804: Disabled SyncIQ Policy is not initially displayed as Policy Disabled in Eyeglass

When the Eyeglass system setting for INITIALSTATE is set to Disabled for Configuration Replication Jobs (Type = AUTO), the Jobs window State for the Eyeglass Configuration Replication Job where the corresponding SyncIQ Policy is disabled displays as “User Disabled” instead of “Policy Disabled”.  In this state the Eyeglass GUI allows you to Enable this Job, but in fact after the next Configuration Replication Job the Job is correctly displayed with the Policy Disabled state.

Workaround: None Required.

—————————————————–

T676: Eyeglass Zone replication Job does not replicate all authentication providers for OneFS 8.0

For OneFS 8.0, if an Access Zone has multiple authentication providers not all providers will be replicated for the Access Zone on the target cluster.

Workaround: Manually edit the Access Zone on the target cluster and add the required authentication providers.

—————————————————–

T723: Job shows OK when there is an Access Eyeglass Zone Replication Error

The Jobs window for an Access Zone replication Job which had a replication error or audit error shows as OK even though an Alarm was issued for the Error.

Workaround: Monitor email for Access Zone replication errors.  Address the replication issues.

—————————————————–

T771: Edit Configuration does not show parent node selected

If a change is made to a Configuration Replication Job to deselect a file sharing object from the job, the parent node where there still are selected objects is no longer selected in the Edit Configuration window.

Workaround: Expand the Inventory View tree for SMB and NFS to see which objects are contained in the Job.

—————————————————–

T805: Eyeglass Configuration Replication Jobs not updated when IP address changed on Source Cluster

An IP address change on the Source Cluster of an Eyeglass Configuration Replication job does not get picked up and the job continues to reference the old IP address resulting in a configuration replication error.

Workaround: Reset Eyeglass to pick up IP address changes for Jobs on the new active cluster

1. Make a record of the state of all Configuration Replication Jobs in the Eyeglass Jobs window - these states will NOT be preserved on the reset:

   1. Jobs which are Configuration Replication type

   2. Jobs that are DFS enabled

   3. Jobs that are User Disabled

2. SSH to Eyeglass appliance using admin: sudo -s enter (must use root)  then use admin password (default password: 3y3gl4ss)

3. set the initial state for all Eyeglass Job types to User disabled

   1. http://documentation.superna.net/eyeglass-PowerScale-edition/Eyeglass-PowerScale-Edition#TOC-igls-adv-initialstate

4. cd /opt/superna/sbin

5. ./reset.sh

6. Once reset completes, go to the chrome browser and refresh the browser and login with the credentials

7. Now, you need to add both of the cluster using Management subnet SSIP.

8. Once it is added, open the Job window - now you will see all the Eyeglass configuration replication jobs are in “user disabled” state

9. .Enable all the Eyeglass configuration Job to DFS Mode if configured

IMPORTANT: You must enable DFS mode before enabling the Job to prevent creation of active shares on target cluster.

1. Enable all configuration replication job (except ones that were previously User Disabled) and run it

T593: Eyeglass errors for multiple exports with the same path

If an Eyeglass Configuration Replication Job contains more than one Export with the same path, this may result in an AUDITFAILED state or configuration replication error  for the associated Eyeglass Configuration Replication Job in the DR Dashboard or a configuration replication error.

Workaround: The following workaround is available to address this issue:

1. Modify exports on the source to add a second path which is a sub-folder of the existing path.  This way Eyeglass will identify each Export uniquely. Example

           Initial State:

            export 1: /ifs/data/folder

            export 2: /ifs/data/folder

           Updated State:

            export 1: /ifs/data/folder

                             /ifs/data/folder/sub-folder

            export 2: /ifs/data/folder

          2) Exports must have different Clients.

T1792: Eyeglass does not auto-detect PowerScale version changes and may use incorrect API version for Configuration Replication

You may see Inventory errors after upgrading the PowerScale cluster version or adding a cluster to be managed by Eyeglass which has a different OneFS version than clusters already managed due to wrong version of API being used to connect to the cluster.

Workaround: Restart the Eyeglass sca service as per instructions here for sca service:

http://documentation.superna.net/eyeglass-PowerScale-edition/Eyeglass-PowerScale-Edition#TOC-Eyeglass-Processes

T1851: Eyeglass Configuration Replication Jobs not removed when there is no SyncIQ privilege for the eyeglass service account

If the eyeglass service account has the SyncIQ privilege removed the Eyeglass Jobs are not updated to removed even though the associated SyncIQ policy cannot be retrieved.  The Jobs run successfully with the message “The job has no data to replicate; skipping it.”

Workaround: eyeglass service account must have the SyncIQ privilege as documented in minimum permissions document here:  http://documentation.superna.net/eyeglass-PowerScale-edition/tech-notes/PowerScale-cluster-user-minimum-privileges-for-eyeglass

—————————————————–

T2193 - Export max_file_size setting not replicated correctly

A large export max_file_size parameter is not replicated exactly to target as it is configured on the source which results in an Audit failure during Eyeglass Configuration Replication.  For example:

Source 4611686018427388000

Target: 4611686018427387904

Workaround:  None available. For smaller values such as 1024 or 1048576 this error does not occur.

———————————-

T2757:  Access Zone is not replicated from OneFS 8 to OneFS 7.2

Access Zone is not replicated from OneFS 8 to OneFS 7.2.

Workaround: Create Access Zone and make updates manually.

—————————————————

T1976 - Eyeglass Jobs Window Edit Configuration does not show related Snapshot Schedules

If a Snapshot Schedule Replication Job is selected in the Jobs window, the Edit Configuration option does not mark the Snapshot Schedules which are included in the Job..

Workaround:  Expand the Snapshot Schedule Job in the Jobs window to see the Source Path.  Manually review Snapshot schedule paths. Any Snapshot Schedule where the path is at or below the Job source path will be included in the Job.

———————————-

T2920:  Access Zone Authentication Provider is not replicated to the target cluster

Eyeglass Configuration Replication does not sync the Access Zone Authentication Provider to the target cluster.

Workaround: Add Authentication Provider to the Access Zone manually.

—————————————————

T3629:  Renamed Snapshot Schedule leaves original Snapshot Schedule on the target

After renaming a Snapshot Schedule, the next Configuration Replication cycle creates the new Snapshot schedule on the target but does not remove the Snapshot schedule with the original name such that on the target they both exist.

Workaround: Manually remove the extra Snapshot Schedule from the target.

—————————————————

T14803 Set Job Type AUTOSKIPCONFIG does not create associated jobs until configuration replication runs

When setting job type for an unconfigured job to type SKIPCONFIG the other relaed jobs for snapshot schedule, zone, quota are not created until the next Configuration Replication cycle has completed.

Workaround: None required - next scheduled Configuration Replication job will rectify and create the jobs.

—————————————————

T15258 Unable to create Custom Job

After creating a Custom Job, it is removed from the Job list after the next Configuration Replication cycle runs.

Workaround: None Available

—————————————————

T15321 DFS share name custom suffix may be doubled

If you have configured a custom DFS suffix, if the source share name already has the suffix it may be added again to target share on replication instead of being skipped.

Workaround: It is not expected for source share name to have the DFS suffix. Please contact support.superna.net for assistance.

—————————————————

T15884 Some scenarios in networking API failures during Configuration Replication may not block deletes

Some scenarios remain after resolution in 2.5.5 T12773 where when Eyeglass has an imcomplete view of PowerScale configuration due to a PowerScale API networking API call failure there is a risk of deleting and readding Eyeglass Configuration Replication jobs and losing their settings such as DFS mode or AutoSkipConfing mode or risk of deleting meta data such as SMB shares or NFS exports.

Workaround: In 2.5.6 all new Eyeglass configuration replication jobs will be in unconfigured state. When activating ensure that you are activating in the correct mode: AUTO, DFS or AUTOSKIPCONFIG.

—————————————————

T16888 Configuration Replication fails if SyncIQ Policy source and target path are different and SyncIQ policy path contains special character

For the case where a SyncIQ Policy path contains a special character and the SyncIQ Policy source and target path are different, configuration replication fails for the associated Eyeglass job with the AEC code AEC_NOT_FOUND.

Workaround: Configuration objects such as SMB shares and NFS exports must be kept in sync on the DR cluster manually. To avoid the replication error on each cycle and keep the SyncIQ policy available for failover the Eyeglass Configuration Replication job can be set to AUTOSKIPCONFIG as per instructions .

—————————————————

T16965 Audit does not consider differences on source and target for SMB share property inheritable_path_acl

For the case where an SMB share has been manually created on the target cluster with a different setting for the SMB share property inheritable_path_acl, the Supena Eyeglass compare of the source and target share does not identify the difference and therefore does not update the target share to match the source share.

Workaround: One OneFS manually change the setting for this property, or if the share on the target cluster is not in use delete it and allow Eyeglass to recreate it.

—————————————————

T17618 SPN repair during Configuration Replication Job does not create missing SPNs

The SPN repair component of the Eyeglass Configuration Job does not create missing SPNs.

Impact: This only impacts creation of SPNs for new SmartConnect zones added in Powerscale. This does not affect SPN create/delete during failover.

Workaround: Create required SPNs for new SmartConnect zones in AD manually.

—————————————————

T18812 Error replicating SMB Share Run as Root permission with local user

In some cases where an SMB share permission is configured with run as root and local users the run as root permissions are replicated to the target as regular permissions and also subsequent attempts to update results in a duplicate permission error.

Workaround: To skip replication of share permissions and properties you can follow the steps here to view the shares and exports that are part of the Configuration Replication Job. To skip replication on a share, uncheck it. Once skipped, manual process will be required to keep share properties and permissions up to date on target cluster.

—————————————————

T19177 NFS modify properties which are not client list fails with unresolvable host

If an NFS export property is modified where the property is not an NSF export client and the client list contains unresolvable hosts, the Eyeglass replication job will fail to update the NFS export on the target with an unresolvable host error even if in Eyeglass the ignoreunresolvablehosts setting is set to true. Note that this is not an issue if an NFS export client list is modified as this results in a delete and create of the export since the client list is part of how we uniquely identify the export.

Workaround: Manually update the export on the target cluster to update for new setting.

Features

—————————————————

T11807 Alarm for quota synchronization error does not contain error details

For case where quota synchronization fails (example advisory threshold configured to be greater than hard threshold), an Eyeglass alarm is raised but the alarm does not contain any details of the error.

Workaround: In Eyelgass Jobs / Running Jobs window tree view under "Group Quota Synchronization Steps" navigate down the tree and find the step with an error. The Info link should contain error details if available.

—————————————————

T9652 Unlock My Files inconsistent handling for unreachable PowerScale cluster

For the case where Eyeglass is managing multiple clusters and one or more clusters are unreachable, the Unlock My Files sometimes displays the error "Failed ot search:","Communication failure or timeout searching for open files. Please try again later or try to be more specific in your query.". without displaying results for reachable cluster or may provide results for reachable clusters without providing the error.

Workaround: Resolve PowerScale cluster reachability issue.

—————————————————

T12307 Cluster Storage Usage may be incomplete

When the API request for cluster storage usage is returned from PowerScale with information missing for one or more nodes, the Eyeglass Cluster Storage Usage window may not display all information for the nodes where information was returned. For example for a 4 node cluster if the API response only contains information for nodes 1, 3 and 4 the Cluster Storage Usage window may only display information for node 1 even though node 3 and node 4 information is available.

Workaround: Use PowerScale tools to determine storage usage.

Superna Eyeglass Known Limitations

Known Limitations for PowerScale OneFS 8.0.0.x with Eyeglass

T507 Cluster Report for OneFS 8.0 missing information

The Eyeglass Cluster Configuration Report for OneFS 8.0 is missing following information:

• DNS and Subnet information

• File System Explorer

• Protocols - new HDFS, FTP, HTTP settings

Known Limitations for Eyeglass Failover

T939  Eyeglass Access Zone Replication Job in Error after failover

The Access Zone Replication Job associated with the SyncIQ mirror policy configuration replication Job has the following error when the SyncIQ policy source and target path are not identical.

Workaround:  Create and update Access Zones manually on source and target cluster and disable Eyeglass Access Zone replication Jobs.  With the Eyeglass Access Zone replication Jobs disabled, the Zone Configuration Replication Readiness Jobs will have a status of Unknown.  This does not block failover.

T1785  Cannot set ignore flag on subnet pool after failback

It is not supported to apply an igls-ignore flag on a subnet pool that has been failed over and failed back such that the SmartConnect Zone has an igls-original prefix due to the fact that on a subsequent failover the igls-original prefix will not be removed and will leave the Access Zone in a state where both directions are failed over.

Workaround:  Manually edit SmartConnect Zone on active cluster to remove the igls-original prefix.  Run Configuration Replication and then run the Failover Readiness job to update Zone Readiness.

T2479: Access Zone Failover fails between OneFS 7.2 clusters if Eyeglass also managing OneFS 7.1

For the case where Eyeglass is managing OneFS 7.2 and OneFS 7.1 clusters, an Access Zone failover between OneFS 7.2 clusters will fail as OneFS7.1 linmap command is attempted and fails.

Workaround: Access Zone failover in this Configuration is unsupported as for Eyeglass Inter-version management, it is expected to apply capabilities of lower versions to all versions being managed and Access Zone failover for OneFS 7.1 is not supported. No workaround required.

T3258: Cannot start failover while Eyeglass initial inventory is running

For the case where Eyeglass has been restarted and the initial inventory is running for initial discovery, while the initial inventory is running a failover cannot be started.  A “Failover configuration is not valid” message will be displayed in the GUI followed by a message that the target cluster is not managed by Eyeglass.

Workaround: Wait for initial inventory to completed before initiating a failover.   Check running jobs windows for the initial inventory job to show completed.

T3774: Failover relies on policy naming: <policy name> and <policy name_mirror>

The Superna Eyeglass failover relies on following naming conventions:

1. First failover A to B- policy name = <policy name>.

The first failover name cannot be <policy name>_mirror.

2. Second failover B to A - policy name = <policy name>_mirror.

Workaround: Manual process on naming the convention above must be followed.

T4808: SPNs not updated for new authentication providers after Access Zone settings changed to “Use all authentication providers” (OneFS 7.2)

If an Access Zone is modified from manually defining the authentication providers to using the “Use all authentication providers” setting in OneFS 7.2, Eyeglass will not update SPNs for any new authentication providers that where not previously provisioned.

Workaround: Manual process required to create these SPNs.

T6229: Existing Failover Logs cannot be reviewed after upgrade to Eyeglass R2.0

Failover logs which were generated from previous releases cannot be viewed from the Eyeglass DR Assistant Failover History view after upgrade to Eyeglass R2.0

Workaround: Generate an Eyeglass Backup and download to your local machine.  The Failover logs are contained in the backup archive in the folder failover_logs.

T14321 Zone/Pool Failover Readiness for AD Delegation validation, SPN Readiness validation not supported for Multi-Site failover configuration

For multi-site failover configuration the AD Delegation validation is not supported as it runs in parallel for both the A -> B and A->C resulting in conflicts and errors for both the self and cross AD delegation testing.

For multi-site failover configuration SPN Readiness validation is not supported as there are 2 pools on the B and C clusters with the same igls-original.... SmartConnectZone name and this cannot provisioned in AD as it does not support duplicate SPNs.

Workaround: For multi-site failover manual verification for AD delegation can be done as documented .

SPN Readiness validation warning cannot be disabled and after manual verification that correct SPNs are present can be ignored.

T15611 Pool Readiness Alarms are reported per Zone

Instead of reporting Pool Readiness alarms per Pool they are reported against the Access Zone that is configured for Pool Failover.

Workaround: None required.

DNS Dual Delegation Failover Readiness Validation Supported DNS servers

DNS Dual Delegation Failover Readiness validation is only supported by design for Microsoft DNS server. This validation must be disabled if any other DNS server is being used. This can be done from the Eyeglass command line using the command: igls adv readinessvalidation set --dualdelegation=false 

T17254 Failover does not take into account Powerscale job retries

In some cases Powerscale will retry a job after it fails and eventually if it succeeds the overall status of the job remains in Needs Attention. Failover logic takes the success / fail status from the first attempt only.

T18556 User Quota Replication requires System Access Zone AD Provider

The API used for creating user quotas requires System Access Zone to be configured with an AD provider to be able to resolve the user SID. If the user SID cannot be resolved the quota creation will fail with the error AEC_BAD_REQUEST "Requested persona was not of user or group type".

Workaround: Add an AD provider to the System Access Zone that has a trust relationship with the other domains in other Access Zones in order for SIDs to be resolved.

Known Limitations for Eyeglass Configuration Replication

Multi-Path Exports

T1359  Update NFS Multi-Path Export path(s) may cause transient Configuration Replication Error

Eyeglass uniquely identifies an NFS Export based on its path.  When the path is changed this results in a Create and Delete operation in Eyeglass.  It may occur that the create is attempted before the Delete is executed. In this case a Configuration Replication error occurs.  This is automatically resolved in the subsequent replication cycle when the new export is successfully created.

Export cannot have multiple paths that span multiple Eyeglass Jobs

Export with multiple paths that are protected by different SyncIQ policies is not supported.  This export configuration is not supported for DR as it would not allow per policy failover and is an unsupported configuration for Eyeglass.

The solution for this is to split the single export into multiple exports each with paths that correspond to a single SyncIQ policy.

T1359  Update NFS Multi-Path Export path(s) may cause transient Configuration Replication Error

Eyeglass uniquely identifies an NFS Export based on its path.  When the path is changed this results in a Create and Delete operation in Eyeglass.  It may occur that the create is attempted before the Delete is executed. In this case a Configuration Replication error occurs.  This is automatically resolved in the subsequent replication cycle when the new export is successfully created.

T1743  Multiple export with same path and same client do not show Configuration Replication Error

Multiple exports with the same path are required to have different clients in order to be replicated as per PowerScale default behaviour.  In the case where they have been provisioned with same client, Eyeglass Configuration Replication will only show error for this condition on the second configuration replication cycle.

T1847  OneFS 8 Overlapping Access Zone Replication has error

In OneFS 8 where there are Access Zones have identical paths, Eyeglass Access Zone Replication will fail with the following error from the PowerScale cluster:  AEC_CONFLICT “field” “path” “message” “access zone base path \*/ifs\* overlaps with base path \*/ifs/data/zone\* in Access Zone Use the force overlap option to override. In this case disable Eyeglass Configuration Replication Jobs for Access Zones and manually create the Access Zone on the target cluster.

T1972  Snapshot schedule replicated with offset

Snapshot schedule expiration offset has OneFS API bug that adds extra time to snapshot expiration when the snapshot schedule is created.  This results in an expiration on the DR cluster, that can be greater than entered on the source cluster. example expire in 20 days will be 22 days on the target cluster.  Different units of off set all result in a value greater than entered. After failover the DR (target cluster) value will be synced back to the source (Prod cluster). Thereby losing the original expiry offset  and extending the expire time by a new offset from the API error. This has been raised with EMC as SR to resolve.

1. Work around:  Before failover ensure a cluster report has been generated (cluster reports icon), or an existing emailed cluster report exists.   Post Failover re-enter the original values on the DR snapshot schedules using the cluster report values from the source cluster as a reference.

2. Another option is disable Snapshot Sync jobs in the jobs window if the above workaround does not meet your needs to preserve expiry of snapshot settings.

UPDATE: Resolution for this OneFS issue is available in OneFS 8.0.0.3

T2046  Access Zone Replication limitation when all user mapping rules are deleted

Access Zone Replication successfully creates and updates user mapping rules and also successfully deletes user mapping rules except when all user mapping rules are removed from the source.  In the case where all user mapping rules are deleted from the source, the Access Zone configuration replication job will not delete all on the target - the user mapping rules remain on the target.

T2241  Incorrect missing SPN alarm issued when PowerScale cluster joined to multiple Domains

In an environment where the PowerScale cluster is joined to multiple Domains, the OneFS SPN check command for a specified domain returns list of SPNs from other domains and lists them as missing.  In this case Eyeglass issues an SPN alarm for missing SPNs based on the list returned even if there are no missing SPNs in the domain specified in the check command.

T2779 - Eyeglass Configuration Replication “Full Sync Mode” always updates when Default Settings on Source and Target cluster are not the same

If on the Source and Target cluster for an Eyeglass Configuration Replication Job the “Default Settings” say for SMB are not the same, each replication cycle will perform an update operation even though the shares are already synced and identical.  Making the Default Settings the same for both clusters will eliminate this behaviour and return to expected behaviour to not perform the update when shares are determined to already be identical.

T2780  Same host moved to different NFS Export Client list not updated on target

For the cases where:

• same host is provisioned on multiple client list and then one host is removed

• Same host is moved from one client list to another

The change in NFS client list is not replicated to the target cluster.  Target cluster client list must be updated manually.

T2908  New Eyeglass Configuration Replication Job cannot recover state and mode from the Eyeglass Fingerprint file.

When a SyncIQ Policy is renamed, Eyeglass considers it to be a new SyncIQ Policy and therefore creates a new Eyeglass Configuration Replication Job with the new name.  The Eyeglass Fingerprint file which holds Eyeglass Configuration Replication Job Mode and State for recovery does not link the original Job name with the new name and can therefore not be used to recover these properties for the new Eyeglass Job.

T4289  Delete Share or Export may result in temporary Audit error

After a share or export is deleted as part of Eyeglass Configuration Replication Job, the next Eyeglass Configuration Replication Job Audit task may incorrectly expect that the object is not deleted resulting in a alarm such as “ Replication job audit failed" - "objects not found on source or target cluster, hence audit fails” .  The error is cleared on the next Eyeglass Configuration Replication Job where the Audit task correctly does not try to audit the deleted object.

T5972  No Error Message for Duplicate NFS Export on OneFS 7.2 Configuration Replication Failed

Duplicate NFS Export on OneFS 7.2 Configuration Replication failure is expected, however in this case there is no specific Info associated with failed step to identify the issue.

T14936 Short SPN not created during Configuration Replication

Eyeglass Configuration Replication will only create full version of SPN, no short version is created. Note that Access Zone and Pool Failover update both short and full version of SPN. If short version is required it can be manually added using AD tools.

T17097 Eyeglass Configuration Replication direction follows Enable/Disable state of SyncIQ policies

Eyeglass Configuration Replication source cluster is the cluster of the enabled SyncIQ policy. If there is a mirror policy and both SyncIQ policies are enabled Eyeglass enters a defensive state showing Policy Disabled for both and no Configuration Replication is done. If a SyncIQ policy is mistakenly enabled on the read only cluster Eyeglass does not evaluate the read/write state and will use the read only cluster as the source cluster for its Configuration Replication job.

Known Limitations for Eyeglass Features

T2350:  Quota Self Serve Portal: Local Group Quotas not displayed when logged in with Local Group User

Quotas associated with a Local Group (for example wheel) are not displayed in the Quota self serve portal when logged in as a Local Group User for that group.

T1962: Default Role incorrectly shows Delete option

Eyeglass User Roles Default Roles incorrectly provide the option to be deleted when in fact they cannot be deleted.

Workaround: None Required.  If the Delete option is selected the Default Role is not deleted.

T7980: Cluster Storage Monitor AD Group Template Quota Creation does not created group quota for nested AD Groups

If an AD Group has sub-groups (nested groups) is configured as a Template for automated group quota creation, no group quotas will be created for sub-groups.

Workaround: Each group that requires automated group quota creation must be explicitly added to the relevant share permissions.

T8362: Cluster Storage Monitor AD Group Template Quota Creation does not respect highest quota settting user quota in nested AD Groups

If an AD Group has sub-groups (nested groups) is configured as a Template for automated user quota creation, user quota creation follows explicitly the quota limit for the sub-group when the user already has a quota for a higher limit. In this case, what should have happened is that template setting is ignored if there is already an existing user quota with a higher limit.

Workaround: Avoid use of nested AD groups for automated user quota creation.

T8193: special charaters in Cluster storage monitor AD managed quota templates is not supported

If an AD Group templates, if the AD group name has special characters in the AD group name the quotas will not be applied.

Workaround: Avoid use of special characters when creating AD groups for AD managed quotas.

T9622: Unlock My Files! does not indicate error when PowerScale node is not reachable

If an PowerScale node is unreachable when Eyeglass is searching for open files there is no error message for the unreachable PowerScale nodes.

Workaround: None available.No open files displayed for unreachable nodes.

T15139 Data Config Migration Concurrent Jobs Limitation

When 2 Data Config Migration Jobs are started concurrently, each runs a separate Configuration Replication Job and the Configuration Replication Job cannot run concurrently. First one must complete before the second one can start.

Workaround: Recommend to run 1 Data Config Migration job at a time.

Known Limitations for Eyeglass General

T2289  Backup Archive Job is not always displayed in the Running Jobs window

In some cases after a Backup Archive job is initiated it will not appear as a running task in the Jobs / Running Jobs window.  Archive is still created and available for download on completion.

T2908  Renamed SyncIQ Policy does not link to RPO Reports from original SyncIQ Policy Name

When a SyncIQ Policy is renamed, Eyeglass considers it to be a new SyncIQ Policy.  Therefore RPO Reporting for the original SyncIQ Policy name will not be linked to RPO reporting for the new SyncIQ Policy name.

T3170 Pending Quota Requests are not preserved on failover

If a failover is done while there are Quota Pending Requests, the Pending Requests are lost as the quota to which the request was originally made no longer exists on the original cluster after failover.  The pending quota request will appear in the Quota Requests History in Error state.

T4579 Upgrade from 1.5.4 to 1.9 and greater Failover History retrieves Failover Log for SyncIQ Job Reports

After an upgrade from 1.5.4 to 1.9 or greater, in the DR Assistant -> Failover History list the link to open SyncIQ Job Reports opens the Failover Log due to fact that prior to this release Failover Log and SyncIQ Job Report log were combined.  In this case you are able to see the SyncIQ Job Reports related to failover at the bottom of the Failover Log.

T6300 After an Eyeglass restore with the -anyrelease option the print screen functionality for SyncIQ Job Reports and Eyeglass backups may be in error

After an Eyeglass restore to a new appliance using the --anyrelease option, print screen functionality may no longer be working due to a incorrect permission setting.  This impacts SyncIQ Job Reports which will be missing the charts and generating an Eyeglass backup with print screens.

To workaround this issue:

1) ssh to the eyeglass appliance and login with the admin account (default password 3y3gl4ss)

2) assume root user by typing

sudo su -

And entering the admin password

3) vi /opt/superna/sca/data/Screenshots.json and write "<placeholder>" as a value in the "plain_text" field and then save it.
4) Copy and paste the following commands:

str=$(sudo cat /dev/urandom | tr -dc 'a-zA-Z' | fold -w 12 | head -n 1)

echo -e "$str\n$str" | passwd screenshots

sed -i "s/<placeholder>/$str/" /opt/superna/sca/data/Screenshots.json

  5) Start a backup with print screens and follow in Running Jobs to verify the backup completes successfully.

T12034 Eyeglass appliance rediscover does not preserve Eyeglass Job state unless Configuration Replication has run

If a change is made to an Eyeglass Job state or Job type and then there is an appliance rediscover before configuration job has been run the changed Job state / type will be lost.

T16137 Anyrelease restore does not restore all Ransomware Defender and Easy Auditor settings

There is no restore of settings from release 2.5.4 and earlier. For release 2.5.4 and earlier continue to capture all Ransomware settings (False Positive, Ignore List, Allowed Extensions, Security Guard) and Easy Auditor settings (Active Auditor Trigger settings, RoboAudit). Post restore verify settings and update where required before cluster up on ECA.

In all cases, restoring an Eyeglass backup using the --anyrelease option will not restore following Ransomware Defender and Easy Auditor settings:

Ransomware Defender: Event History, Threats Detected

Easy Auditor: Finished Reports, Scheduled Reports, Saved Queries
