Re: vg00 size
/stand will need to be able to handle a few more kernels, I typically shoot for 33% full so I have flexibilithy n a crisi.
/var is too small. It should double. This depends on use. We have a print spooler on /var and during certain peak periods usage spikes up a lot. /usr looks good. /opt looks a little full, and 11i has larger more varied optional software.
If you want to increase root / you need to take a make_tape_recovery boot off the tape,manually intervene in the reinstallation and set sizes.
This methodology will work for any fileystem, but root requires contiguous space so there is no choice with that.
The real issue here is what do you plan to use the system for. Not knowing that, my recommendations are broad and based on my experience. Are they relavent to you? Tell me what your server does.

Re: vg00 size
If you plan to Ignite, I would recommend to do your sizing right away while you can interrupt the process and change the size of your LV as you go. Now, it all depends to what OE you intend to go (and I would recommend looking at the installation book for reference), but with what I see there, I would say you're good enough with / but I would bring up /stand to 200Mg as well. I would maybe increase /var/ to about 2 Gb just to be safe. And though this is to be used for update-ux, I would still use the increase for /usr and /opt as per the manual even if I would do a cold-install. So I would say a good 600-800 Mg free space in both /usr and /opt should be good..
But again, I would definitely check into what OE you install and the recommendations as per the manual

Re: vg00 size
You cannot add a 32 GB disk to vg00 unless otherwise MAX_PE * PE_SIZE >= 32 * 1024
If max_pe multiplied by pe_size is less than 32* 1024 then only way you can add 32 gb disk to your vg00 is by reigniting the system.

Re: vg00 size
Having said all this (and with the assumption that you have OnlineJFS), as long as /, /stand, and primary swap are adequate there's no real reason to sweat the others. These three must be contigious and can't be extended but the remaining filesystems can be extended "on the fly".
The thing that is missing from your list is the swap space and dump space -- and the amount of physical memory you have and whether you are running pseudoswap and if you ever truly swap. With that extra bit of data, it's possible to answer more fully.

I think 112MB is minimum for 11i - you should be ok - increase is hard to do - have to boot into LVM maintenance mode...
I think you may need more free space in /opt - check the 11i readme doc....
check firmware (PDC Firmware Revision needs to be at 41.02 or higher - if not - book HP to update.):

Re: vg00 size
We've had it a few times where it cored and no one noticed. They launch the gui as root from roots home. They are big enough cores to fill up /.
No points for this, just an anecdote of our experiences.

Re: vg00 size
I will obviously be igniting to tape and restoring the entire vg00 to the new disks.
The system runs OpenView Communications Assurance OVC/A which uses Oracle. The new disk is driven by an Oracle upgrade from 8.0.6 to 8.1.7 which requires more space.
The system also uses MC/ServiceGuard, but the shared disks will not be modified.

Re: vg00 size
/stand - 112MB
/ {root} - 140MB
/home - 20MB
/opt - 1000MB
/tmp - 64MB
/usr - 500MB
/var - 500MB
SWAP = 2 x memory size
this is all just informative, i would never use these sizes myself.
FYI, 11.0 has all the same recommendations as 11i, except that stand is 84MB.

Re: vg00 size
About the size of swap,
normaly 2 times the physical Mem, but with these amounts of mem (single oracle database plus application), 2.5 GB primary swap and you could add secondary swap when needed.

Re: vg00 size
I would add a separate /var/adm/crash mount point = 1 x memory + 512MB (for your system 3GB)
For example, for SAP, you need 24GB of swap.
Also check your kernel parameters - DBC_MAX_PCT should be set to an ammount to give you between 300-500 MB.
So for you, in the 11 to 20 % range.
Again, that depends on what application you are running...
