how can I extend the logical volume containing /usr ?

I have HP-UX 11.00, no Online JFS.
If it weren't for STRESS I'd have no energy at all

Hi,

You will have to shutdown and boot your server in single user mode.

Hello,

1. Bounce the box into single user mode.

2. lvextend -L new_size_in_MB /dev/vg00/lvolX

3. extendfs -F fs_type /dev/vg00/rlvolX

4. mount /usr

5. bdf and verify new size

6. Bounce the box into multi-user.

Hope this helps!

Shutdown and come up in single user. The commands needs are lvextend and extendfs -- both of these are statically linked and thus do not need /usr mounted to run. You should print the man pages out beforehand because you won't have them in single-user mode.
If it ain't broke, I can fix that.

Unfortunately /usr is one of those filesystems that you cannot unmount. Therefore you will need to do the following:
Reboot
Interrupt the boot sequence and type "hpux -is" then when prompted for interact with IPL say Y.
lvextend -L /dev/vg00/
extendfs /dev/vg00/
