Primary/Remote Volume & Failover - Clarification?

Paul Hutchings — Sun, 05 Feb 2012 15:41:59 GMT

Can I just confirm that my understanding from the manuals is correct please?

If I'm replicating from Site A to Site B using Remote Snapshots:

The volume at Site A is Primary
The volume at Site B is Remote
Any volumes assigned to servers at Site B cannot be accessed/mounted so long as the volume is a Remote volume.

In the event that Site A fails/disappears:

The volume at Site B is changed to Primary (manually or scripted)
Any servers assigned to this volume can now do an iSCSI rescan and mount/access the volume

When Site A is back:

Change the volume at Site A to remote or create a new remote volume
Do a remote snapshot from Site B to Site A to copy the volume back
Change the volume at Site B to remote, and change Site A back to Primary.

Is that a reasonable understanding? I know there are failover/failback wizards in the CMC but I want to be sure my understanding of things is correct first.

Thanks,

Paul
