PowerMax Driver - Retype from non-replicated to replicated volume type fails to create volume on remote array

[Simon O'Donovan]

When retyping from non-replicated to replicated Volume Type, if there are existing RDF pairs on Asynchronous or Metro replication then device creates on the remote storage group will fail. A replication group consistency check will prevent the creation of the new device.

    PowerMax Driver - retype attached replication fix

    Fixes for retyping attached volumes when moving from
    non-replicated to replication enabled volume type.
    Cases fixed:
    -Retype to metro replication with existing pairs.
    -Retype to non-replicated after retyping to metro.
    -Retype to asynchronous replication with existing pairs present.
    -Delete attached volume with asynchronous replication after
    attaching to an instance.
