Specifies additional devices for paging and swapping.

SYNTAX


swapon --- -a ---|

swapon --- device_name ---|


Warning: See restrictions, Chapter 18, AIX Programming Tools and Interfaces.

DESCRIPTION

The swapon 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
swapon normally occur in the system multi-user initialization file /etc/rc
making all swap devices available, so that the paging and swapping activity is
interleaved across several devices.

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.

Normally, the -a argument is given, causing all swap or paging devices (as
determined by the "swap" attribute being true) in /etc/filesystems to be made
available.
