swapon(1M)                     DG/UX 5.4R3.00                     swapon(1M)


NAME
       swapon - specify additional devices for system 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 swap devices in /etc/fstab.  A secondary swap device entry
       in etc/fstab would be as follows:

            /dev/dsk/swap1   swaparea   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.

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.
