Active hub co-situated with primary managed cluster

1. On a hub recovery RDR setup, ensure backups are being created on active and passive hub clusters. Failover and relocate different workloads so that it is finally running on the primary managed cluster after the failover and relocate operation completes. Ensure latest backups are taken and no action of any of the workloads (cephfs, rbd- appset and subscription type each in distinct state like Deployed, FailedOver and Relocated) is in progress.
Also have a few workloads running on the secondary managed cluster.
2. Collect drpc status.

Ensure data sync is progressing well. Perform site failure meaning bring primary managed cluster along with active hub down.
3. Ensure secondary managed cluster is properly imported on the passive hub and wait for DRPolicy to get validated. 
4. On checking the drpc from passive hub, it was found that Progression state is different which is based upon last known state of the individual workloads.

5. Since primary managed cluster is still down, data sync can't progress. Now perform failover of all the workloads which were running on the down cluster to the secondary or failovercluster and track it's progress.

After failover from C1 to C2-

Cluster C2 with name amagrawa-c2-3jan is the secondary or failover cluster which is up and running while C1 (from the logs) is down.

Actual results: From the above drpc output, failover did not even start for any of the RBD workloads. However, it did for a few cephfs but not for Cephfs workloads under NS busybox-workloads-7, 8 and 9.


Logs before peforming hub recovery is kept here- http://rhsqe-repo.lab.eng.blr.redhat.com/OCS/ocs-qe-bugs/bz-aman/12jan24-active-415/

Logs from passive hub after performing failover- http://rhsqe-repo.lab.eng.blr.redhat.com/OCS/ocs-qe-bugs/bz-aman/13jan24-after-failover/



Expected results: Failover should progress, all the workload pods should be up and running on the failovercluster and VRG both states should be marked as Primary.
