VxRail: Migrating a Virtual Machine (VM) From vCenter, The Migrate Option Is Grayed Out

The affected VM is not removed from disabled_methods after completing a previous backup.
In this case the Avamar backup is running. The VM should be removed from disabled_methods after completing the backup.

To resolve this issue, follow the steps below: 

1. Take a snapshot of the vCenter VM.
2. Log in to the vCenter mob using this URL:
   

   https://vcenterIP/mob

3. Find the affected VM moref ID.
4. SSH to vCenter and stop the vpxd service.
   

   service-control --stop vmware-vpxd 

5. Enter into VCDB.
   

   /opt/vmware/vpostgres/current/bin/psql -d VCDB -U postgres

6. Verify the content of the disabled methods table and see if the affected VM is there.
   

   select * from VPX_DISABLED_METHODS WHERE ENTITY_MO_ID_VAL = 'vm-ID from step 3' 

7. Delete this affected VM entry.
   

   delete from VPX_DISABLED_METHODS WHERE ENTITY_MO_ID_VAL = 'vm-ID from step 3'

8. Start the vpxd service.

   service-control --start vmware-vpxd

9. Log in to the vCenter web client, and see if the VM migrate option is visible again.
