swap space increase in hp-ux11.23

[rajesh73]

Physical ram is 8 GB

Primary swap is /dev/vg00/lv012 -8GB

I want to extend my swap is another 5 GB. Please help

My vg00 have 20 GB free space

Vg00 have software raid, please help me

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

thanks for your update

now the i create the lv and add the lv using swapon command

my lv name is /dev/vg00/swap2

please find the below entry is correct or not

/dev/vg00/swap2 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

Regards.

You just edit /etc/fstab.

[rajesh73]

thanks for reply, but i need nfs file system entry in /etc/fstab

[Dennis Handly]

>but I need NFS file system entry in /etc/fstab

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
