NAME
       admdevice - administer devices

SYNOPIS
       admdevice -o configure device ...

       admdevice -o deconfigure device ...

       admdevice -o specify [ -s ] device ...

DESCRIPTION
       The admdevice command provides a few management operations whose
       nature is independent of the type of device being managed.  The
       devices should be specified using the DG/UX Common Device
       Specification format, as described in an appendix of Customizing the
       DG/UX System.

   Operations
       configure Configure the device into the kernel.  Only the superuser
                 can configure a device.

       deconfigure
                 Deconfigure the device.  The device must not be held open
                 by either an application program or another component of
                 the kernel.  For example, physical disks cannot be
                 deconfigured while they are registered.  When a device is
                 deconfigured, as far as the kernel is concerned, it doesn't
                 exist.  Only the superuser can deconfigure a device.

       specify   Display the canonical device specification string for the
                 device, in either long (default) or short format.  The
                 device being specified must be configured.

   Options
       The specify operation may be accompanied by the following option:

       -s        Short.  The standard abbreviation for the device
                 specification for the device is displayed.  This may
                 actually be longer than the device specification given on
                 the command line, in order to provide a consistent
                 appearance for similar devices.  If the abbreviation table
                 does not include an entry for the device, then the full
                 (long) specification is displayed.

EXAMPLES
            # admdevice -o specify 'sd(ncsc(),0)'
            sd(ncsc@7(FFFB0000,7),0,0)
            # admdevice -o specify -s 'sd(ncsc(),0)'
            sd(ncsc(0,7),0,0)


DIAGNOSTICS
   Exit Codes
        0     The operation was successful.

        1     The operation was unsuccessful.

        2     The operation failed due to access restrictions.

        3     There was an error in the command line.

        4     Device given for specify operation is not configured.

NOTES
       The AV/Alert server program (dgsvcd) sometimes holds open physical
       devices in order to monitor their status.  This can make it
       impossible to deconfigure the device.  If this is the case, the
       commands
            /usr/sbin/init.d/rc.dgserv stop
       and
            /usr/sbin/init.d/rc.dgserv start
       can be used before and after the admdevice command to disable and
       enable the AV/Alert software.
