Considerations and limitations for Dell EMC PowerStore plug-in
The following considerations and limitations are applicable:
In SAN environment:
Snapshot Manager for Data Center does not discover the cloned volumes during discovery.
The cloned volumes never expire. You can manually delete the cloned volumes from NetBackup during deport and delete operations.
Volumes from multiple appliances are not allowed within the same volume group. All Volumes must reside on the same appliance.
If a protection policy is assigned with a volume group, you cannot assign a protection policy to an individual resource within the group.
The volume groups do not support mapping and unmapping, the workaround is to attach and detach the host with each volume in the volume group separately.
Single volume restore operations are only allowed when write order consistency is disabled on the volume group.
Before restoring a snapshot, you must shut down the application and unmount the file system that is running on the production host. Also, delete the host cache to prevent data corruption during the restore operation.
In NAS environment:
All snapshots are captured at the file system level and the snapshots are in read-only mode.
The limit for the file system name is 255 characters. NFS export or SMB share name is 80 characters on the array. For a snapshot name, the maximum length must be 255 characters.
Dell EMC PowerStore plug-in does not support point-in-time (PIT) rollback restore of shares using snapshots.
