Filo,

First I would question why you need to extend /stand. The size of /stand should be quite static and somewhere around 100MB should suffice (64MB minimum - no more than 128MB max). If your /stand falls within this range then you need to look at what's filling it.

If you do need to expand, do an Ignite backup/restore. Do a "vgexport -p -s -m /tmp/vg??map /dev/vg??" for each of your non root VGs. Download the latest Ignite from here:
http://www.software.hp.com/products/IUX/index.html
Run a "make_tape_recovery -a /dev/rmt/?mn -I -v -x inc_entire=vg00". Then boot off that tape and you'll be led through an interactive restore that allows you the opportunity to resize your file systems. When you're done, run a vgimport for all your non-vg00 VGs ("mkdir /dev/vg??", mknod /dev/vg??/group c64 0x??0000", "vgimport -s -m /tmp/vg??map /dev/vg??") and you're done.

Do your tape as follows:

#!/usr/bin/sh
/opt/ignite/bin/make_tape_recovery -Av -x inc_entire=vg00

make_recovery is obsolete and should not be used.

Recovering from the tape created by my script will not touch vg01 or other vg's.

You can and should back up, but you don't need to.

Filo,

I got it this from this forum. Forget who post it.. It works I have test it

Assumptions,

01. You are not just an "HP kid" who will play with ignite like stuff.

02. You like taking some risk & saving your valuable time

Size of /dev/vg00/lvol1 is A (boot or /stand or /dev/vg00/lvol1)

Size of /dev/vg00/lvol2 is B (swap or /dev/vg00/lvol2)

You wanna increase size of lvol1 from A to A+X (where X is not more than B - "physical memory installed in your machine")

Basically we have to decrease size of swap to increase boot as they are contigous.

Now Extending /stand is an easy job which can be performed in 10-15 minutes.

Steps

01. Boot your machine in LVM maintenance mode
(hpux -lm at ISL>)

#rm /etc/mnttab
#vgchange -a y /dev/vg00
#lvrmboot -r /dev/vg00
#lvremove /dev/vg00/lvol2
#lvextend -L "A+X" /dev/vg00/lvol1
#extendfs /dev/vg00/rlvol1
#lvcreate -L "B-(X+10)" -C y -r n -n lvol2 /dev/vg00
#lvlnboot -b /dev/vg00/lvol1
#lvlnboot -r /dev/vg00/lvol3
#lvlnboot -s /dev/vg00/lvol2
#lvlnboot -d /dev/vg00/lvol2
#reboot -r

You have your /stand extended now
