Re: swap space increase in hp-ux11.23

You would be better off creating a new swap device as it is not easy to extend /dev/vg00/lvol2 since lvol1, lvol2 and lvol3 MUST be contiguous.

 

Create a new logical volume:

 

lvcreate -L 5120 vg00

 

Then activate it:

 

swapon /dev/vg00/lvol#

Use whatever lvol name that was assigned above.

 

Don't forget to add it to your /etc/fstab file like:

 

/dev/vg00/lvol# ... swap pri=1 0 0

Hi

 

 

Don't forget to replicate de mirror to he new lvol ( this is important to have redundancy in the disks )

 

lvextend -m 1 /dev/vg00/lvol_created /dev/dsk/disk_device_for_mirror

What has this to do with adding that swap entry?  Another new question?

You can have all sorts of entries in /etc/fstab.

Rajesh,

 

Edit the /etc/fstab file add the below line to the end.

 

# vi /etc/fstab

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

 

Mirroring

lvextend -m 1 /dev/vg00/swap2 /dev/dsk/cxtxdx

the cxtxdx should be replaced with your lternate disk name.

 

Regds,

Pramod
