swapon(1m)                 DG/UX 4.30                  swapon(1m)



     NAME
          swapon - specify additional DG/UX System device for paging

     SYNOPSIS
          /etc/swapon -a
          /etc/swapon name ...

     DESCRIPTION
          Swapon specifies additional devices for paging.  The system
          begins by paging on just one device so that only one disk is
          required at bootstrap time.  Calls to swapon normally occur
          in the system rc script chk.system in the /usr/sbin/init.d
          directory.  By default, this will invoke swapon the first
          time you change init run levels.  See the file
          /etc/dgux.params to set the argument to the swapon command
          in the rc script chk.setup.

          Normally, the -a argument is given.  This makes available
          all devices marked as sw swap devices in /etc/fstab.  A
          secondary swap device entry in etc/fstab would be as
          follows:

               /dev/dsk/swap1   swap_area   swap sw x 0

          The second form of swapon makes the individual block-special
          devices specified on the command line available to the
          system for swap allocation.

     SEE ALSO
          swapon(2), fstab(4).

     FILES
          /dev/dsk/*     Potential paging devices

     BUGS
          You cannot stop paging on a device.  Therefore, you cannot
          use swapon for devices that may be dismounted during system
          operation.
