Rebuilding the kernel

Chris Bidwell — Mon, 04 Feb 2002 17:10:46 GMT

I have an HP9000 Server w/ v11.0 on it. When it begins to boot, it locks up to a certain point and I am unable to continue from there. I can break into the boot sequence, but cannot start SAM or do many other things. I'm thinking I may need to rebuild my kernel. If so, could someone please give me the procedures to doing this? I'd greatly appreciate it. I'm still very much a greenhorn in the HPUX field but am learning as I go.

Hi Chris:

If you can boot and some of your startup scripts execute -- as it sounds from your description -- then I'd suspect that you may merely have a problem in a startup script, perhaps one for networking.

What does the checklist on the console show and/or post the output of /etc/rc.log.

Regards!

Hi
You may have a corrupted /etc/inittab.
try booting single user:
At isl interract with IPL (Y), enter hpux -is.
Does this work?
what do you see?
If inittab is corrupted, look for lines that hve been added or modified (syntax...)

Hope this helps a little

All the best

Victor

Well, I started another boot sequence and on the start up sequence it just locks up when trying to start NFS client subsystem. After a few minutes just goes blank and I'm unable to interact with it from that point.

OK. Here's what you need to do:

Once you are to a point where you can log into the system, go to the /etc/rc.config.d directory and look at the nfsconf file.

If you are not using NFS, AUTOFS or AUTOMOUNT, look for the following lines and make sure they all have a value of 0.

NFS_CLIENT=0
NFS_SERVER=0
PCNFS_SERVER=0
AUTOMOUNT=0
AUTOFS=0

NFS is automatically enabled on all machines. If you do not use it, you have to turn it off yourself.

Hi,

You can configure nfsconf file to not to start during boot.

The file you need check is /etc/rc.config.d/nfsconf

Replace 1 with 0 (Zero) infront NFS_CLIENT, NFS_SERVER, AUTOMOUNT and START_MOUNTD
And the reboot once again.

Goodluck,

Okay, I finally found out that I'm locking up when attempting to start the mail daemon. Who could be the primary cause of this? Thanks for your help guys...
