AIX

The best I could find was

comp.unix.aix: Re: 4.3.3 & CDROM Installation (44P-170)

and

comp.unix.aix: AIX machine won't boot - LED says 0518

My own horror story as follows Nekochan Net • View topic - RS/6000 7043 43P Model 140 CDROM firmware question

You should, at this point, NOT boot from an installation CD but a DIAGNOSTIC CD. Probably your rootvg is seriously damaged and the only remedy is a reinstall.

With the diagnostic CD boot up, exit to a maintenance shell and save your work (if there is any), then reinstall the system.

If you have a mirrored rootvg (you should always have this) you could try to split up the mirror (/usr/sbin/unmirrorvg rootvg; /usr/sbin/reducevg rootvg hdisk<X>). Install to the now freed disk and boot from there. Once the system is up and running again, you can try to import the old rootvg and revive its filesystems to get off any data you might want to keep. At last remove this old rootvg and remirror - it pays to have the rootvg always mirrored.

I do not have a diagnostic CD. Do you know where I can get one or an image of one? Since IBM does not support AIX 4 any longer, I would not think I could order one from them.

It's worth asking though.

Just sent an e-mail to IBM, asking for CD or image...

I am downloading both of the CD52035.iso and CD51025.iso images, maybe I can use one of these. I think they are for AIX 5 and I might have to update the firmware to get them to work but it's worth a shot.

I am sorry, but i have to correct myself (don't know, where i was with my thoughts when i wrote this):

The correct file is /etc/netsvc.conf of course. The line in there should read:

Code:

hosts=local8,bind8

You should be able to boot into single-user mode by hitting "5" as the system boots (although it might be F5, it depends on the model).

Err, what's "local8,bind8"? Using "local,bind4,bind" makes more sense (use "etc/hosts", then check DNS for IPv4, then check DNS for IPv4/6).

Also, make sure the hostname is in /etc/hosts. CDE expects the local hostname to always be resolvable and reachable. You might just want to make the hostname an alias of "localhost".
