You can increase or decrease the size of the VxVM paging volume. You can resize the volume regardless of whether the current state of the volume is active or not active.

Specify the size of the volume, with one of the following suffixes: k/K/m/M/g/G. If you do not specify a suffix, the size is in number of blocks. (This differs from the command when -t lv or -t nfs, which defaults to the size in number of LPs.)

For example, to increase the size of the swap volume by 1000M:

# chps -t vxvm -s 1000M myswapvol

# lsps -t vxvm -a 
PageSpace   VxVM-Device    DiskGroup  Size    %Used  Active  Auto  type 
myswapvol   ibm_ds8x000_5  mydg       1.95g   0      no      yes   vxvm 

For example, to decrease the size of swap volume by 1000M,

# chps -t vxvm -d 1000m myswapvol 

# lsps -t vxvm -a 
PageSpace   VxVM-Device    DiskGroup  Size    %Used  Active  Auto  type 
myswapvol   ibm_ds8x000_5  mydg       1000m   0      yes     yes   vxvm
