AIX

Our offshore team tried to do some patching for me over the weekend, and while I'm not completely sure of how we got into this state, I know it started with them forgetting to put the alt_rootvg back to sleep before rebooting the server.

Our process is this: Clone/update_all using alt_diskinstall. Wake up alt_rootvg, do more patching.. put alt_rootvg back to sleep and then reboot.

Since he forgot the step that puts it back to sleep, the system wouldn't boot. And that's where the steps get fuzzy.. I can see where he removed the alt_rootvg disk, cleared it's pvid, etc.

And somehow now, we're left with a system that appears to be up and functional, but it's booted off of old_rootvg. The rootvg is there when you do lsvg, but not when you do lsvg -o. There is also no pv with rootvg on it.

lsps -a returns errors, because there's no active rootvg. I can't reclone, remirror, etc to try all the normal things I would do to get out of this.

How do I get old_rootvg renamed to rootvg?

Code:

# ls -al /dev | grep '17,  1'
brw-------    1 root     system       17,  1 Apr 22 2011  hdisk0
crw-------    2 root     system       17,  1 Apr 22 2011  ipldevice
crw-------    2 root     system       17,  1 Apr 22 2011  rhdisk0

# lspv |grep hdisk0
hdisk0          00f635667efba750                    old_rootvg

Hi,

The best option is restore mksysb.
