HP LeftHand fails to rename volume after migrate

[Anthony Lee]

After you migrate a volume to a LeftHand backend, the volume is not renamed and the volume IDs no longer match.

This is due to update_migrated_volume() missing from the LeftHand driver.

    LeftHand Add update_migrated_volume to drivers

    The LeftHand drivers were missing the method
    update_migrated_volume, which was causing the volume IDs
    to no longer be accurate after a volume was migrated into
    a LeftHand array.
