Background re-mirror aborted due to drive shut down.

        Occurs on:  SFT II and TTS.

        Meaning:  The REMIRROR console command was used to remirror two
                drives and the background copy process was aborted due
                to a drive failure.  This is not a fatal error.
                However, the current remirror process will be aborted.

        Cause:  The mirror drive or associated disk channel components have
                failed.

        Solution:  Make sure that the drive is powered on.  Check all of
                   the components of the failed disk channel.  Repair or
                   replace the drive, controller, or Disk Coprocessor
                   board that is defective and then attempt to remirror
                   the drive again.
