In Short,
What you did is incorrect and its not possible.
In detail,
Swap space is the same as RAM since this is a virtual memory OS. Therefore, swap space can never be reduced on a running system, whether it is used/reserved or not. There is nothing to change in fstab except to remove additional (secondary) swap space. the primary swap space can never be removed or reduced in size except by reinstalling (ie, using Ignite/UX). If you are removing secondary swap space, you remove the entry from fstab and then reboot. You can add swap space at any time with swapon.
Moral : You cannot remove swap without a reboot.
DB
i found solution if i installed swapoff software in hp-ux i can remove swap without rebooting
Any error?
is it successfull when you umount to this volume?
ok problem already solved 
You didnt say what version of HPUX you were running... (swapoff is to my knowledge only for 11.31...)
