Bug Description

When multipath is enabled on the n-cpu host, the 3PAR iSCSI driver will create a new VLUN with a new LUN ID for each path for the same volume. The 3PAR should use the same LUN id for each path.

    3PAR use same LUN id for each export path

    When multipath is enabled, and the 3PAR driver is configured
    to export a VLUN over N iSCSI IP(ports), we now use the same
    LUN ID for each iSCSI IP export. Previously, when we would
    export a volume over N iSCSI ports, we would get a new LUN ID
    for each iSCSI port.
