You also have to take into account that you are restricted to what you can dynamically assign by the 'maximum' values for cpu/memory you have set in the profile.
If you dynamically assign it, you don't need to reboot.
However if you want it to be permanent you will need to change the profile for that lpar, shut it down and then activate it from the HMC - a reboot will not activate the new profile, it has to be shutdown and then activated.
I've used this method with SAN disks (but not rootvg), the problem is you have to varyoff/on the VG.
How about assigning bigger SAN disks to rootvg then migratepv old to new, then remove old?
I'm using the following to backup a directory"
^ There, you've just said it, use the backup command :)
find /dir/to/backup|backup -ivqf /dirtobackupto/filename.bak
restore -xdqvf /dirtobackupto/filename.bak
would restore it back exactly as it was.
I have recently migrated LPAR's from Power5 (dedicated resources) to Power6 (VIOS clients) using mksysb with no problems.
The only difference to your scenario was that the LPAR's were upgraded to AIX 6.1 beforehand - this was because we are using TSM and the IBM TSM support team only support...
There is only one way I know to get it 'back to normal':
Run multibos -R to remove standby LV's (multibos -Rp to preview).
If it removes the normal hd5 etc (and leaves bos_hd5) you will need to run multibos again:
multibos -sX (sXp to preview)
set bootlist to the new hd5, reboot, and then...
You need to make sure you only have hd5 as the boot logical volume on your root disk.
For instance if you had previously used multibos and had hd5 and bos_hd5, alt disk would fail on that as it's hard coded to only use hd5 (and cannot rename bos_hd5), cleaning up multibos to leave just hd5...

I have written a script now to get it from the unique_id - the problem was the LUN ID would appear differently depending on whether it was ESS or DS.
The storage unit identifer appears in the unique_id field as well, so my script looks for that and does one thing for ESS and...
