To attach a board to a domain:
==============================

#.  ``domain_switch`` to the appropriate domain
#.  Execute drshell by entering ``dr``
#.  ``init_attach ${board}``
#.  ``complete_attach ${board}``
#.  ``reconfig``

To detach a board from a domain:
================================

1.  ``domain_switch`` to the appropriate domain
2.  ``drain ${board}`` If the drain fails, check the following:

    1.  Turn off netbackup: /etc/init.d/netbackup stop
    2.  Remove the sg driver from the modules by executing::

            modinfo | grep sg # Note the module number.
            modunload ${mod_number}

    3.  Remove the scsi tape driver from the modules by executing::

            modinfo | grep st # Note the module number.
            modunload ${mod_number}

    4.  If drain is still failing, execute ``drshow unsafe`` and 
        troubleshoot any remaining unsafe drivers

3   ``complete_detach ${board}``
4.  `` reconfig``
