patch / single user mode
So I did lvextend and when I was trying to extend filesytem I counld not. umount /usr or umount /var
I got a message device busy.
So question is what filesystem must be mounted to do anything.
Also how do I logon as single user mode?
is console mode or single user mode are the same thing?

Re: patch / single user mode
alternatively depending on what your system is and how big you can also use ignite to create a system bootable tape then restore it specifying new filesystem sizes interactively.

Re: patch / single user mode
providing you can shut down your machine
etc/shutdown -hy now
power system back on and press space bar to interrupt boot cycle.
type "bo" to restart boot cycle
when asked if you wish to interract with IPL say YES
now type "hpux -is"
at the hash prompt you are logged in as root in single user mode

Re: patch / single user mode
In order to extend the file system you must unmount it, as you discovered. In the case of /usr and /var, they are used so much that the only real way to get them unmounted is to reboot in single user mode. This is done by interrupting the boot process at the "10 second" message, interacting with ISL, and entering "hpux -is" at the ISL prompt. When you're done, just reboot the machine.
In the case of /var, it might be a good idea to check if it could be cleaned out to release some space - perhaps in /var/tmp, or use the cleanup command to remove superceded patches.

Re: patch / single user mode
You can check to see if you have it installed by swlist. But it does require a license so even if it's installed you may not be able to extend on the fly if you haven't put the license in yet. You can check to see if its licensed by on 11.11:
alcatraz:root /root # vxlicense -p
vrts:vxlicense: INFO: No valid license installed
alcatraz:root /root #
The other way to tell is after lvextending your lvols you run the fsadm -F vxfs -b bytesize /mountpoint it will say if your licensed also.
You would have to be on the console to be in single user mode since you won't have network connectivity.

Re: patch / single user mode
What you want to do is also very easy to do if you have Ignite/UX on the system. It is almost always woth the trouble. If you ever need to resize the root volume /dev/vg00/lvol3 you will need to have made an ignite image. Consider HP's Ignite/UX if there is any possibility of further resizing...
