SWAPON(8)                                               SWAPON(8)

     NAME
          swapon - specify paging/swapping device

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

     DESCRIPTION
          Swapon is used to specify additional devices on which paging
          and swapping are to take place.  The system begins by swap-
          ping and paging on a single device so that only one disk is
          required at bootstrap time.  Calls to swapon normally occur
          in the system multi-user initialization file rc(8) making
          all swap devices available, so that the paging and swapping
          activity is interleaved across several devices.

          Normally, the -a argument is given, causing all devices
          marked as ``sw'' swap devices in /etc/fstab to be made
          available.

          The second form gives individual block devices as given in
          the system swap configuration table.  The call makes only
          this space available to the system for swap allocation.

     BUGS
          There is no way to stop paging and swapping on a device.  It
          is therefore not possible to make use of devices which may
          be dismounted during system operation.
