Hi Ralf,
Add another swap using sam, you cannot increase the size of the existing (needs to be contiguous) without using Ignite (reinstall with new values...)and a reboot...


All the best

Hi Ralf,
if i don't get wrong
you can't increase swap space but you can add another "lvol" as swap space, something like this example:

lvcreate -n lv_swap_1 -C y /dev/vg01
lvextend -l 512 /dev/vg01/lv_swap_1 /dev/dsk/c1t0d0


then do the command :

swapon -a

(this is on 11.00).

also after you create the new lv for swap, when your setting priorities, if your swaps share the same disk, make sure you DON'T set their priority the same make the new one pri=2. As swaps with the same priority on the same disk will result in performance problems.
