 NAME
      mirrortab - mirror disk-log format

 Remarks:
      Mirror facilities require installation of optional DataPair/800
      software (not included in the standard HP-UX operating system) before
      they can be used.

 DESCRIPTION
      mirrortab is a file describing all mirrors on the system.  This file
      is created and maintained by the mirrorlog daemon (see mirrorlog(1M).

      There is one line in the file for each mirror.  Each line contains the
      following blank-separated fields in the order shown (see mirror(1M)
      for definitions of terms):

           primary device      Pathname of the primary section of the
                               mirror.  The name of the mirror is the same
                               as the name of the primary device.

           primary state       State of the primary section of the mirror.
                               Possible values are ONLINE, indicating that
                               the section is in operation; OFFLINE,
                               indicating that the section is not available
                               for use; and REIMAGE, indicating that the
                               section is in the process of being brought
                               into agreement with its ONLINE counterpart.

           secondary device    Pathname of the secondary section of the
                               mirror pair.

           secondary state     State of the secondary section of the mirror
                               pair.  Possible values are as described for
                               primary state.

           fail                Mirror fail flag.  Possible values are GOOD,
                               indicating that neither of the sections
                               making up the mirror pair has experienced a
                               failure, and FAIL, indicating that one of the
                               sections making up the mirror pair has
                               failed, and thus is OFFLINE.

           clean               Mirror-clean flag.  Possible values are
                               CLEAN, indicating that the two sections
                               making up the mirror pair are guaranteed to
                               be identical, and DIRTY, indicating that the
                               sections may differ.
