Problem with drive nn: Mirror drive was shut down.

        Occurs on:  SFT II and TTS.

        Meaning:  This error message occurs on bootup and indicates that
                  the file server could not properly configure a
                  mirrored set of drives because the mirror drive was
                  shut down.  This is not a fatal error.  However, the
                  problem should be investigated as soon as possible to
                  reduce the risk of losing valuable data.

        Cause:  This could be caused by a failure in the mirror drive,
                Disk Coprocessor board (DCB), controller, or connecting
                cables.

        Solution:  Ensure that the mirror drive, the DCB, and the
                   controller are properly seated, connected, and
                   powered on.  Look up any additional error messages
                   displayed and use any suggestions found there. Use
                   the PREPARE utility to re-setup Hot Fix and mirroring
                   on the drive.  If this still does not fix the
                   problem, exchange the above mentioned components one
                   by one with known good components until the problem
                   component is found.
