The next will be /var unless it was installed with a FS of 2 GB...
A few things: Is your root VG (vg00) mirrored? Which means whatever space left in the VG is to be divided by 2...
/var will be like /usr: SAM uses it... so unless you have OnlineJFS you are to learn "how to" for a few things without SAM, the easy way round is to have a ignite tape, but I suppose you have no DAT device installed?
So its not complicated:
1 - Bring the Box into single user (or boot into single user...)
2 - lvextend -L SSS /dev/vg00/lvolX (SSS in Megabytes...)
3 - umount /dev/vg00/lvolX
4 - extendfs /dev/vg00/rlvolX (notice the "r" in rlvolX)
5 - mount /dev/vg00/lvolX
If it does not automatically backup lvm structure, ->
vgcfgbackup vg00
You should know where the system saves LVM and Filesystem information:
look at /etc/lvmconf /etc/lvmtab /etc/fstab
The commands you need to know for disks and LVM:
pvcreate
pvdisplay
pvchange
vgcfgbackup
vgcfgrestore
vgcreate
vgextend/vgreduce
vgexport/vgimport
vgremove
vgdisplay
lvdisplay
lvcreate
lvextend
lvremove
newfs
extendfs
Not bad for a start? (Read the man pages and feel welcome to ask here if some of it isnt clear...)
Good luck
