Bug Description
The 3PAR driver assumes there will only be 1 volume attached to a single host at any time. From the cinder perspective this is always true as multi attach is NOT supported currently in cinder. During nova vm live migration, nova bypasses cinder's checks to a volume being already attached and asks cinder to attach the same volume to another host. Then nova asks cinder to detach the volume from the original vm host. This fails for 3PAR because the driver doesn't look for a VLUN on a host. It assumes there is 1 volume on 1 host always.
The 3par drivers fail at detach time saying it can't find the VLUN on the existing host.
