I run ovirt in my homelab, and have an Equallogic PS6000. I did this the other week, and it took about 8 to 10 minutes for the VMs to start coming back. I run my engine off of the SAN, and it had some trouble coming back because ovirt was in a lease lock situation. The engine VMs did pause, but the switchover took too long and it killed it. The other HA VMs were just killed and restarted after the storage issue. It did sort itself out, but the equallogic took its time to do the controller switchover.

Do you have an idea how long will it take ? No, it has been years and years since I had to do a switchover on an EqualLogic (they mostly just run). I know I've read of others using EqualLogic's for oVirt, so I'm hoping for someone who's experienced a switchover...
Keep in mind that in case the domain is declared unavailable (reached a threshold , which I doesn't know) , all VMs using it will be paused and oVirt will try to recover them once the storage is back available. Right - with the hosted engine on the SAN, I am also curious how that is impacted (how will the engine HA tooling handle a pause).
