Hi Dan,
The way you describe it I should have 2 storage backends with 2 IPs
for the same SAN backend, right? The problem I see is that when you
create a disk for a VM, you assign it to only one storage domain... so
if the first fails, how will oVirt know which one should use as failover?
No, multipath is the *same* storage (ie LUN) exposed via two different
network paths.
