SYNTAX

     DSTAT [ ldev ]
           [ ALL  ]


PARAMETERS

ldev                An integer specifying the logical device
                    number of the disk drive whose status is
                    requested.

ALL                 Displays the status of all disk drives,
                    both system and nonsystem.  The default is
                    that if no parameter is included, only the
                    status of nonsystem disks is displayed.


OPERATION

     The DSTAT command is used to display the current status of one
     or more disk drives on the system.

     For example:


     VSCLOSE PROD_SET; SPLIT
     DSTAT

     LDEV-TYPE      STATUS         VOLUME (VOLUME SET-GEN)
     ----------     --------       ------------------------
     1-07935       MASTER         MEMBER1 (MPEXL_SYSTEM_VOLUME_SET_0)
     2-07935       MEMBER         MEMBER2 (MPEXL_SYSTEM_VOLUME_SET_0)
     3-07935       MEMBER         MEMBER3 (MPEXL_SYSTEM_VOLUME_SET_0)
     4-07935       MEMBER         MEMBER4 (MPEXL_SYSTEM_VOLUME_SET_0)
     15-07935      MASTER         MEMBER1 (USER_VOLUME_SET_0)
     16-07935      MASTER         MEMBER2 (USER_VOLUME_SET_0)
     17-07935      UNKNOWN


     Disk Drive Status

     Status         Meaning

     UNKNOWN        The system cannot recognize the volume label on
                    the disk.

     SCRATCH        The volume has been erased through use of
                    disk or mountable volume.

     LONER          The volume is a member of a volume set whose master
                    is not mounted, or is a master with the same
                    volume set name as one that is already
                    mounted.

     MASTER         The volume is a recognized master volume of a
                    volume set.

     MEMBER         The volume is a recognized member volume of
                    a volume set.

     If you have purchased Mirrored Disk/XL, you may see PENDING
     or DISABLED as well.  PENDING indicates the partner disk failed
     to mount; DISABLED indicates the volume is not available to the
     system due to a disk failure.  If you have Mirrored Disk/XL you
     may see the following suffixes in the status portion of the
     display:

     -MD         Mirrored disk
     -SU         Split user volume
     -SB         Split backup volume

     This command may be issued from a session, job, program, or in
     BREAK.  Pressing [BREAK] has no effect on this command.
