Overview

The new LiveOPS DR testing 2.0 feature replaces the 1.0 implementation.  This is based on writeable snapshots and test access zones created for dev\test or DR testing, or application upgrade testing.

Use Cases

1. DR Testing
2. Application upgrade simulation testing
3. Dev OPS development
4. File System testing
5. ACL scripting tests (better safe then sorry)
6. Just because it's cool

Requirements

1. Eyeglass 2.5.8.2
2. Onefs 9.3 or later
3. SnapshotIQ license

Configuration

1. This feature will create a snapshot on the path you want to present in the testing Zone.
2.   
3. Create a DR test access zone anywhere in the file system but the name of the zone must start with igls-xxxx  where xxxx is any descriptive name (do not use special characters).  NOTE:  You can create more than one test access zone to create DR test zones or dev/ops test zones.
4.      
5. Create an IP pool to attach to this new Access zone,  create a smartconnect name for mounting and complete DNS delegation steps following PowerScale documentation.
6. Open DR Assistant and Click Writeable Snapshots tab
7.  
8. Click + Create Writeable Snapshot, 
   1. Select your source cluster from inventory
   2. Select a path to A) Create a new source path snapshot on demand OR B) use an existing snapshot by entering a path where a snapshot already exists.   
   3. Click copy Config check box or uncheck it.  This option reads all the shares, exports and quotas found under your selected source snapshot to copy into the DR Test access zone.
   4. Select an Access zone that was created for this testing area.  Note the Access zone should be created specifically for DR testing and you should not select a production access zone.   It is best if this is an empty access zone with no data.
   5. Enter an subfolder underneath the access base path to create the writeable snapshot and present the data.  NOTE:  SMB, NFS shares will be created under this path relative to the location under the source snapshot.
9. 
   
10.   
11. When the form is completed, click submit.  This will launch a job and you can view the job status from the running jobs.  This job will create the writeable snapshot and copy the configuration data into the new access zone that was auto detected.
12.  
13. Verify the access zone has the configuration data using Onefs GUI
14.  
15. Mount your Access zone IP pool created above with smartconnect name to test testing.
16. NOTE:  Make sure you mount the correct smartconnect name if you plan on doing destructive testing to the data.  It is easy to make a mistake and mount the wrong smartconnect name.

How to Delete your testing Snapshot and or Configuration Data

1. Login to eyeglass
2. open DR Assistant
3. Click Writeable Snapshots tab
4. Select the testing snapshot to delete.
5. Select option to delete the snapshot and configuration data or only the snapshot.  NOTE: Keeping configuration data when no path exists will block mounting the configuration data unless a new writeable snapshot is created.
6.  
7. A job will be launched to delete the select configuration and snapshot in running jobs window.
8. Done.
