Is failback supposed to occur while replica is offline?

Post by davidb1234 » Aug 22, 2012 1:10 pm

I am testing DR failover and fail back. Someone from the support line told me that if you do a failover it would be smart enough to power off the VM in the production network before failover. that is not the case.

So i am asking for help from experienced people here.

Now that I have failed over to my DR network with a test VM do I need to shut down the replica before failing back or is failback meant to occur with the replica still online?

Once failback is complete will it power down the replica and power on the original at the production site?

Once failback is complete will the REIP rules still be applied so that I need to manually change the IP information for the production network or will it revert the IP changes it made during failover?

Failover does not touch the original VM, as we cannot know if you are doing test failover into isolated network, or real failover (in which case, presumably, production VM would be dead anyway).

Failback, on the other hand, does take care of power states automatically.

Re-IP rules are applied automatically on both failover, and failback.
