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. Change-Id: I4d28d8ed2375f68eed511de5c25898362eac1def Closes-Bug: #1867163

This PowerMax driver moves the legacy shared volume from the masking
|
|
view structure in Ocata and prior releases (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 intended volume is migrated without
|
|
exposing other volumes in the storage group. The staging storage group
|
|
and masking views facilitate a seamless live migration operation in
|
|
upgraded releases.
