I recently purchased an old 44P. I'd initially had problems getting it
to boot properly and bring up the installer. Finally cleared that hurdle.
Unfortunately, now, the installer is failing with 0516-070 and 0516-862
errrors. Basically, it seems that, when the installer attempts to create
the rootvg, it's not able to clear the drives of old information so that
it can create the new rootvg and lvs. I tried going into the boot-time
maintenance mode to dink with things:

* `chpv -C` fails with an error indicating the disk is part of an
imported vg
* Trying to remove the PV information from the disks with `chpv -r`
just hangs (Just for grins, I let it run while I was gone for a few
hours).
* the boot/install CD's RAMFS doesn't seem to include commands that
should allow me to change these (no exportvg, rmdev, etc.)

How do I clear these disks off so that the installer will be able to
actually use them to install software onto them? Any suggestions? Is
there a format utility on the CD's RAMFS that would allow me to simply
blank the disks so that the `mkvg` will actually work?

chdev -l <hdisk> -a pv=clear
to remove pvid from disk.

this should help.
but it would be better if you can send me output of:
lspv
lsdev -Cc disk

so I can tell exactly want command you need

After dinking around for a while, it became aparent that there was something
amiss with one of the drives. Ultimately, the drive that was being flakey
failed enough I was able to load AIX onto it. At which point, the system
diagnostics tools showed that the drive had died (electronics were still
there so it could identify the drive, but the drive was failing the unit
ready queries). So, gotta get a new drive.

Oh well, hopefully I can now get on with getting used to administering AIX
as my primary interactive system.
