We have learned about how to check current usage of paging space in the previous post, let's see how we change the value in this post.
[root@primary01 /]# lsps -a
Page Space Physical Volume Volume Group Size %Used Active Auto Type Chksum
hd6 hdisk0 rootvg 512MB 2 yes yes lv 0
Increase Paging Space
It's 512 MB currently, which is 1 logical partition in the system. Now, we'd like to raise it to a larger size, say 16 GB which requires additional 31 logical partitions.
[root@primary01 /]# chps -s 31 hd6
We have add some space on /dev/hd6. Let's check it again.
[root@primary01 /]# lsps -a
Page Space Physical Volume Volume Group Size %Used Active Auto Type Chksum
hd6 hdisk0 rootvg 16384MB 0 yes yes lv 0
Now, we have 16 GB of paging space.
Reduce Paging Space
On the other side, we can use -d option to subtract some logical partitions from it to reduce the size of paging space.
For example, if we'd like to revert the adding action in the above, we can do this:
[root@primary01 /]# chps -d 31 hd6
The space is reduced.
