Controlled Failover Option Results Summary

The following table indicates which failover steps are executed based on whether or not the Controlled failover option was selected when the Access Zone failover was initiated.

Steps	Description	Executed on	Access Zone	Controlled Failover selected	Controlled Failover NOT selected
1 - Ensure that there is no live access to data	Check for open files. If Open files found, decide whether to failover or wait to be closed.	Source	Manual	Not applicable - manual step	Not applicable - manual step
2 - Begin Failover	Initiate Failover from Eyeglass	Eyeglass	Manual	Not applicable - manual step	Not applicable - manual step
3 - Validation	Wait for other Eyeglass Failover jobs to complete	Eyeglass	Automated by Eyeglass	Step Executed	Step Executed
4 - Synchronize data	Run all OneFS SyncIQ policy jobs related to the Access Zone being failed over	Source	Automated by Eyeglass (all policies in the Access Zone)	Step Executed	Step NOT Executed
5 - Synchronize configuration (shares/export/alias)	Run Eyeglass configuration replication 1	Eyeglass	Automated by Eyeglass (based on matching Access Zone base path)	Step Executed	Step Executed based on last known data in Eyeglass *If you do not want this, uncheck the “Config Sync” option to skip this step
6 - Synchronize quota(s)	Run Eyeglass Quota Jobs related to the SyncIQ Policy or Access Zone being failed over	Eyeglass	Automated by Eyeglass (based on matching Access Zone base path)	Step Executed	Step Executed based on last known data in Eyeglass
7 - Record schedule for SyncIQ policies being failed over	Get schedule associated with the SyncIQ policies being failed over on OneFS	Source	Automated by Eyeglass	Step Executed	Step NOT Executed
8 - Prevent SyncIQ policies being failed over from running	Set schedule on the SyncIQ policy(s) to manual on source cluster	Source	Automated by Eyeglass	Step Executed	Step NOT Executed
9 - Provide write access to data on target	Allow writes to SyncIQ policy(s) related to failover2	Target	Automated by Eyeglass (only for policies that match the Access Zone Base path)	Step Executed	Step Executed
10 - Disable SyncIQ on source and make active on target	Resync prep SyncIQ policy related to failover (Creates MirrorPolicy on target) from OneFS	Source	Automated by Eyeglass	Step Executed	Step NOT Executed
11 - Set proper SyncIQ schedule on target	Set schedule on MirrorPolicy(Target) using schedule from step 6 from OneFS for policy(s) related to the Failover	Target	Automated by Eyeglass	Step Executed	Step NOT Executed
12 - Remove quotas on directories that are target of SyncIQ (PowerScale best practice)	Delete all quotas on the source for all the policies	Source	Automated by Eyeglass	Step Executed	Step NOT Executed
13 - Change SmartConnect Zone on Source so not to resolve by Clients	Rename SmartConnect Zones and Aliases (Source)	Source	Automated by Eyeglass (Requires IP pool hints are configured See docs)	Step Executed	Step NOT Executed
14 - Avoid SPN Collision	Sync SPNs in all AD providers to current SmartConnect zone names and aliases (Source)	Source	Automated by Eyeglass (AD delegation must be completed as per install docs)	Step Executed	Step Executed
15 - Move SmartConnect zone to Target	Add source SmartConnect zone(s) as Aliase(s) on (Target)	Target	Automated by Eyeglass (Requires IP pool hints are configured See docs)	Step Executed	Step Executed
16 - Update SPN to allow for authentication against target	Sync SPNs in all AD providers to current SmartConnect zone names and aliases (Target)	Target	Automated by Eyeglass (Requires IP pool hints are configured See docs)	Step Executed	Step Executed
17 - Repoint DNS to the Target cluster IP address	Update DNS delegations for all SmartConnect Zones that are members of the Access Zone	DNS	Potentially Automated by Eyeglass (See Script Engine Docs)	Not applicable - manual or scripted step	Not applicable - manual or scripted step
18 - Refresh session to pick up DNS change	Remount the SMB share(s)	SMB Client Machines	Manual on clients (NOTE: DNS servers and clients cache DNS entries which will require touching the client or intermediate DNS servers to clear DNS caches (on Windows ipconfig /flushdns)	Not applicable - manual step	Not applicable - manual step

Initiates Eyeglass Configuration Replication task for all Eyeglass jobs
SyncIQ does NOT modify the ACL (Access control settings on the file system). It locks the file system. ls -l will be identically on both source and target
