Name
       swapon - specify additional device for paging and swapping

Syntax
       /etc/swapon -a
       /etc/swapon name ...

Description
       The command is used to specify additional devices on which paging and swapping are to take place.  The system begins by swapping and paging
       on only a single device so that only one disk is required at bootstrap time.  Calls to normally occur in the system multi-user  initializa-
       tion file making all swap devices available, so that the paging and swapping activity is interleaved across several devices.

       Normally, the option is given, causing all devices marked as ``sw'' (swap devices) in to be made available.

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

Restrictions
       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  dur-
       ing system operation.

Files
       Normal paging devices
