Hi,

Being a newbie, I have a very noob question to ask about AIX5.3
At my company, we have to resize a partition mounted from a Storage
Area Network which is a RS4500 Array of RAID 5 redundant disks. I do
not have the skills to do this on my own.
We could go through resizing the volume form the FAST900 console which
said it was successfully done.
Though, from my tty, I can't see the partition size updated, which is
still used at 99%, becoming very critical for the database runnning
core business jobs.
Here what I get when issuing lsvg

[root@p5_dev /]# lsvg -l vg-dev-sbl
vg-dev-sbl:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT
POINT
sbl_lv jfs2 158 158 1 open/syncd /siebel
loglv00 jfs2log 1 1 1 open/syncd N/A

And here lspv's output

[root@p5_dev /]# lspv
hdisk9 00c4c08ebffb2f80 vg-dev-inf
active
hdisk11 00c4c08ebffb3653 vg-tools

hdisk15 00c4c08ebffb32e7 vg-dev-sbl

Since we have a database running on that filesystem, we cannot afford
unmount/mount the filesystem.
Does anyone have a solution for this annoying problem ?
thanks in advance

Grateful for any piece of help

Hindsight being 20/20 in the future to avoid disruption you are better off
presenting a NEW lun to the AIX system that you can then just extendvg,
rather than extending the LUN from the SAN.
