Adding swap device from a logical volume in HP-Ux


1) Use  swapinfo command to view the current status of swap devices.

#swapinfo

2) Create a new logical volume called lv-swap, in the vg01 volume group, to be used as a secondary swap device.

#lvcreate -L 1000 -C y -n lv-swap vg01

3) Edit the /etc/fstab file to add the swap device.

#vi /etc/fstab
Add the line: /dev/vg01/lv-swap /swap swap 0 0

4) Activate the new swap device.

#swapon –a

5) Finally, check the swapinfo for the newly added swap device.

#swapinfo
