PowerMax Driver - Legacy volumes fail to live migrate
The fix moves the legacy shared volume from the masking view
structure in Ocata and sooner (when SMI-S was supported) to staging
masking view(s) in Pike and later releases (U4P REST).
In Ocata, the live migration process shared the storage group,
containing the volume, among the different compute Nodes. In PIke,
we changed the masking view structure to facilitate a cleaner live
migration process where only the volume is migrated and not all the
other volumes in the storage group. The staging storage group and
masking views facilitate a seamless live migration operation in
upgraded releases.
