I have a 44P-170 (7044-170) machine that has 4.3 ML11 installed on it and I am having a problem with NFS/NIS at boot. The machine will boot all the way up to the CDE login screen but when I log in as root, the screen goes black and will stay that way overnight. I have tried a console login as well and then I just the message:
NIS: server not responding for domain "pacnet"; still trying
repeated over and over.
How do I or can I disable NFS/NIS during the boot process so I can get access as root to fix the problem?
I have been trying to boot off the media I have 4.3.3 but it will stop after the timestamp message and the LED display is: 0518. I believe this error refers to a console error, but I am not sure how to get past it. I have tried to set the console to the monitor/keyboard/mouse I have set up. I am working off a monitor through a KVM but the keyboard and mouse are hooked up directly to the machine.
So I have set up a hyper terminal session with a laptop and connected through a serial cable and I am still having the 0518 LED display come up, when I try to boot CD. Any suggestions? The terminal settings are:
Bits per second: 9600
Data Bits: 8
Parity: None
Stop Bits: 1
Flow control: None
Yes, I am seeing output to the terminal screen, here's a snapshot of the tail end:

Not using any method to boot from CD except for putting CD into drive and then changing the boot settings in SMS to boot from the CD first.
A - Yes, Keyboard, mouse and screen are unplugged.
B - Yes, I changed SMS through serial port to boot from CD
C - Yes, CD-ROM light flashing at startup. I did change it back to HD boot once to see what would happen but got the same NIS problem as before (Got log in screen but once root password entered never got prompt.
I received the machine with BASE 4.3.3 installed, I am not sure if base OS was installed from CD or through network connection.
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.
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.
