Adding additional paging space : Use mkps command.

bash-3.00# mkps -a -n -s 32 myvolvg
paging00
bash-3.00#

Verify the newly added paging space:

Once added, you can see the paging space in /etc/swapspaces.

bash-3.00# cat /etc/swapspaces
* /etc/swapspaces
*
* This file lists all the paging spaces that are automatically put into
* service on each system restart (the ‘swapon -a’ command executed from
* /etc/rc swaps on every device listed here).
*
*
* This file is modified by the chps, mkps and rmps commands and referenced
* by the lsps and swapon commands.

hd3:
dev = /dev/hd3
paging00:
dev = /dev/paging00

Check the status using lsps command.

bash-3.00# lsps -a
Page Space      Physical Volume   Volume Group    Size %Used Active  Auto  Type
