There can be easiest way to do it is take ignote backup with interactive option and while restoring choose new desired size of File systems.
Or alternatively you can do this in single user mode.
boot m/c in single user mode using hpux -is option but root required contiguous block so you may require to do some more excercise so best is use Ignite option.

You can only extend this logical volumes (/) using ignite. You first create a bootable ignite tape, boot from it, extend the size. The reason you can't do this with the standard commands is that / /stand and the primary swap partitions must be contiguous.
Y
ou can extend the others (/usr and /var) by booting your system into single-user mode and extend them that way.

Interrupt the boot sequence
Interact with ISL --> yes
from the ISL prompt
ISL>hpux -is

# lvextend -L /dev/vg00/lvol?
# extendfs /dev/vg00/rlvol?

# mount -a
# init 3 (or whatever your default run level is or press control-D)

You can get ignite from here:
http://www.software.hp.com/products/IUX/download.html

Documentation from here:
http://www.docs.hp.com/hpux/onlinedocs/B2355-90767/B2355-90767.html

To cut a bootable interactive ignite tape
# make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

There is no way to extend root / other than with the Ignite method.

root requires contiguous space and you only get a shot at that when you install or reinstall via Ignite.

If you have onlineJfs, you can extend /var any time you want.

If you don't have onlineJFS, you have to extend /var in single user mode.

Boot

Interupt the 10 Second prompt.

Y Interact with the IPL
hpux -is

lvextend /dev/vg00/lvol# I think the # is 8 on a standard install.
