MSA1000 Failback

[Josh Safranek]

I simulated a failover by disabling the HBA port in our switch. It failed over fine, but now what is the proper way to get it back? I'm nervous about reversing the procedure, disabling the backup HBA and having the system decide there are no paths left.

Also, I do not have SecurePath only basic MPIO

The basic MPIO does not have a management interface, so you cannot force a failback that way. You can only simulate another failure which causes the MPIO to do another failover (back) to controller-1 -- or leave it in the current state.

It seems to have failed back to the primary controller overnight. Is this normal or would is it cause for concern that a condition forced it back to the primary?

That does not sound OK to me. I would take a look into the Windows event log.
