Shalom,

swapinfo -tam

See what swap is allocated.

If there is more than one area you may safely eliminate one of them, sam is the simple way.

If however there is only one, you will need to do what you wish and set up a newer, smaller logical volume to be a smaller swap.

That means after lvremove you will need to do lvcreate and lvextend to the desired size.

The minimum size of swap for HP-UX is 50% of system RAM.

Hi:

In addition to my remarks in the post by me that Pete cited, if you are running 11.31 you can use 'swapoff' and skip the reboot necessary to deactivate the secondary swap.
