Environment

VMware Live Recovery Manager 9.x
VMware Site Recovery Manager 8.x

Cause

To prevent potential issues during test failovers, especially with Pure Storage's SRA (Storage Replication Appliance), ensure that your volume names do not exceed 42 characters.

Test failovers of Volumes, Volume Group Volumes or Pod Volumes are expected to fail if the character length of the volume name exceeds 42 characters.

If the volume name exceeds 42 characters, then during the test failover when the volume is renamed with the "-puresra-testFailover" suffix, the volume name will exceed 63 characters and the test failover will fail.

Resolution

Ensure the datastore name on the source site is not more than 42 characters.

When using ActiveCluster with SRM, when testing a Recovery Plan, the test can fail if the [pod_name::volume_name]-testFailoverStart exceeds 42 characters. The failure will note that the volume was unable to be created.
