If you have unneeded swap space, you can remove it.
Become superuser.
Remove the swap space.
# /usr/sbin/swap -d /path/filename |
The swap file name is removed so that it is no longer available for swapping. The file itself is not deleted.
Edit the /etc/vfstab file and delete the entry for the swap file.
Recover the disk space so that you can use it for something else.
# rm /path/filename |
If the swap space is a file, remove it. Or, if the swap space is on a separate slice and you are sure you will not need it again, make a new file system and mount the file system.
For information on mounting a file system, see Chapter 39, Mounting and Unmounting File Systems (Tasks).
Verify that the swap file is no longer available.
# swap -l |
The following examples shows how to delete the /files/swapfile swap file.
