VMAX - FC - Cleanup of Initiator group fails

[Ciara Stacke]

When the last volume has been deleted from the Storage Group and the Masking View has been deleted and the initiator group is no longer in use, the deletion of the Initiator group fails.

The initiator group does actually delete off the backend, but the code throws an error message

Bad or unexpected response from the storage volume backend API: Unable to terminate volume connection: (4, u'One or more parameter values passed to the method are not valid. (com.emc.cmp.osls.se.symm.impl.ArrayInitiatorMaskingGroup.show:143 C:ERROR_CLASS_SOFTWARE F:ERROR_FAMILY_NOT_FOUND file: ArrayInitiatorMaskingGroup.cpp line: 176 func: show message: Supplied Masking Group OS-irco3sd22vm01-F-IG not found)')

The problem occurs in using the now deleted initiator group as a parameter to search for remaining masking views

    VMAX driver - Cleanup of Initiator group fails

    When the last volume has been deleted from the Storage
    Group and the Masking View has been deleted and the
    initiator group is no longer in use, the deletion of
    the Initiator group fails. The initiator group is actually
    deleted off the array, but the code is throwing up an
    error when it uses the now deleted initiator group
    name to search for remaining masking views. The
    solution is to check if the initiator group has been
    deleted by common.terminate_connection before searching
    for remaining masking views.
