Add 4GB swap as per request.

#lvcreate -C y -L 4093MB -n swap2 /dev/vg00 /dev/dsk/c2t1d0

#lvextend -m 1 /dev/vg00/swap2 /dev/dsk/c3t0d0

#swapon /dev/vg00/swap2

#Add the entries in /etc/fstab


/dev/vg00/swap2 ... swap pri=1 0 0

hi,

if the second swap is on the disk where is already the primary swap, you could have performance issue.

the best way is to create the ignite and restore in advanced mode of ignite, increase the primary swap space.

>>#lvcreate -C y -L 4093MB -n swap2 /dev/vg00 /dev/dsk/c2t1d0

command has got syntax error .

and it should be

lvcreate -C y -L 4093 -n swap2 /dev/vg00 /dev/dsk/c2t1d0



Also consider create swap area in another VG for better performance ..

Hello,

I followed the same way but for new volume group not vg00. You can hit below commands it is successful in my production environment.


Add 4GB swap as per request.

#lvcreate -L 4093MB -n swap2 ex: swap2 vg00
#lvextend -m 1 /dev/vg00/swap2 /dev/dsk/c3t0d0

#swapon /dev/vg00/swap2

#Add the entries in /etc/fstab
/dev/vg00/swap2 ... swap pri=1 0 0
