HPUX 11i upgrade from 11

[Adam Noble]

Hi,

I'm attempting to generate a process for upgrading a number of server to 11i from 11. I am restricted due to /stand from simply upgrading and am forced to do a clean install.

My question is can I simply clean install and then re-import my volume groups (obviously export them 1st)....data resides on external emc disk. I would prefer to do this rather than restore from backup.

Adam,

That is exactly the approach you need to take. Export the vg(s) with "vgexport -s -m /tmp/vg??.mapfile /dev/vg??", then, after install, import them with:

mkdir /dev/vg??
mknod /dev/vg??/group c64 0x??0000
vgimport -s -m /tmp/vg??.mapfile
vgchange -a y vg??

Obviously you need to transport the mapfile from old to new systems.

cheers Pete just wanted to ensure that was the case. To clarify I am nit clean installing onto alternate hardware it will be the same system, but I think you understood that.

Yes, even on the same hardware you need to figure out a way to transport the map file. You can't put it on the VGs to be imported because they're not available at the time the map file is needed (obviously), so you need to put it on external storage. Be aware that the mapfile isn't even necessary if your logical volumes follow conventional (default) naming standards: lvolnn where nn matches the logical volume minor number. Check the vgimport man page.
