VPG0043 – The Microsoft default SAN policy might cause VM ‘{VM_name}’ (VPG ‘{VPG_name}’) volumes to become offline upon recovery

KB Number:
000001150

Symptoms:
You may receive an alert: The Microsoft default SAN policy might cause VM '{VM_name}' (VPG '{VPG_name}') volumes to become offline upon recovery.

Alternatively, when performing a Zerto Move or Failover operation, one of the recovery disks for a protected vm fails to mount on the recovered vm on the DR site. The disk comes up in offline mode and has to be manually brought online. This issue occurs with disks using the PVSCSI driver.

Cause:
Versions of windows above 2003 have a default diskpart policy that is set to "Offline Shared". This causes the disk to be mounted in offline state.
 

Solution:

 The resolution requires setting the diskpart policy to "OnlineAll" using the following steps:

1) Open the command prompt on the relevant vm.
2) Launch "diskpart"
3) Type "san" to confirm the server is set to "Offline Shared"
4) Typed "san policy=OnlineAll"
