HUR reverse sync from SVOL to PVOL

Hello List,

 

Quick question for a DR scenario where the primary storage is intact but DR operations have occurred at the secondary site. Let's say I split the HUR group and made them writable to the secondary host. Now, the primary host is back up and I want to fail back to the primary. What is the correct and *least* complex way to do this? In testing, I have used this command from the remote site...

 

pairresync -g <group> -swaps

 

This resyncs but swaps the SVOL with the PVOL and in testing this works. Once the group reaches PAIR status I split the group from the primary side and issue the same pairresync command to swap back. In testing this seems to work just fine.

 

Is there a better or preferred way to do this?

 

Thanks,

Vic
