To show the current paging space volume, its size along with other information use the ‘lsps’ command:

#lsps -a
Page Space      Physical Volume   Volume Group    Size %Used Active Auto   Type Chksum
hd6             hdisk1            rootvg        1024MB     1   yes   yes    lv     0

The paging space may be increased on the fly using the ‘chps’ command. In order to increase this paging space to 2 GB we need to to find out the PP size, since chps will increase the paging space by the specified number of PP’s

# lslv hd6
LOGICAL VOLUME:     hd6                    VOLUME GROUP:   rootvg

MIRROR WRITE CONSISTENCY: off
EACH LP COPY ON A SEPARATE PV ?: yes
Serialize IO ?:     NO
INFINITE RETRY:     no

On this system is the PP size 128M so in order to increase the paging space size to 2Gig we need 8 PP’s
