HP-UX to increase the size of logical volume

Question:
we have HP-UX 11.0(64-bit) installed on HP900(N4000) server. I want to increase the size of logical volume /dev/vg00/lvol9 (filesystem: /m01) to 3260M. This volume has mirrored copy on other disk. Here are the steps I am going to follow:

lvextend -L 3260 /dev/vg00/lvol9
unmount /m01
extendfs vxfs /dev/vg00/lvol9
mount /m01

please coreect me if I am missing anything.

 

Answer:

There are a couple of things that you may want to add to your procedure:

# fuser -k /m01
# umount /m01
# lvextend -L 3260 /dev/vg00/lvol9
# extendfs -F vxfs /dev/vg00/rlvol9
# mount /m01

The steps you were missing or incomplete were:
You need to kill all processes accessing any file mounted on /m01
You should unmount the filesystem before you extend it.
You need to make sure you use the RAW (character) device for the volume group in question.

I hope this helps.
