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 512MB 2 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 16 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 LV IDENTIFIER: 0005e4b80000d7000000013e5a69cf95.2 PERMISSION: read/write VG STATE: active/complete LV STATE: opened/syncd TYPE: paging WRITE VERIFY: off MAX LPs: 512 PP SIZE: 256 megabyte(s) COPIES: 1 SCHED POLICY: parallel LPs: 2 PPs: 2 STALE PPs: 0 BB POLICY: non-relocatable INTER-POLICY: minimum RELOCATABLE: yes INTRA-POLICY: middle UPPER BOUND: 32 MOUNT POINT: N/A LABEL: None 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 256M so in order to increase the paging space size to 2Gig we need 62 PP’s
