We just had a power failure in the primary site and all VPG’s are delta synching. Is it OK to run a failover test on a VPG while the VPG is delta synching?
You are not able to run a failover test on a VPG while that VPG is in the middle of a delta sync.
The reason for this is because a delta sync is a complete resync of the replica disk so once that starts we can unmount that drive to spin up a test.
I hope this helps to answer your question.
