Couple of choices.

1. if you can add extra disks to (vg00) you can /tmp FS extend in fly.

2. if not, as mentioned earlier you have Free PE under (vg 10) which you may recreate /tmp on your desired size . But this requires (downtime ) & hope you have backup of /tmp File system.

Workout plan:-

# lvcreate -L /dev/vg10/lvolxx
# newfs -F vxfs -o largefiles /dev/vg10/rlvolxx
# mount /dev/vg10/lvolxx /new_tmp
# cd /tmp; fbackup -f - -i . | (cd /new_tmp; frecover -f - -r)

(You can also use ,tar,cpio, any backup SW to restore /tmp)

Boot the server into Single user mode / Maintenance Mode

# umount /tmp
# lvremove /dev/vg00/lvolxx
# mount /dev/vg10/lvolxx /tmp

Hi,

You have only one disk in vg00
You can add one more disk to vg00
pvcreate newdisk
vgextend vgoo newdisk
lvextend tmploicalvolume newdisk
fsadm -b newtoaltmpsizeM /tmp

Hi Srik,
You can not extend an LV from vg00 to vg01. If you have sparedisk add disk to vg00. orelse check for whether the size of any other LV can reduce or not( which is having some free space in it ). In that way you will get some PE to use for /tmp
