Error while compiling kernel

vdg1683 — Sat, 10 Sep 2011 16:38:23 GMT

Just had to reinstall 11.00 on a rp2470 box from scratch. The OS installed fine. However, upon trying to install any additional kernel patches or any package that needs a kernel re-compile, I get the following error:

NOTE: Building a new kernel based on template file "/stand/system"
config: error in opening file -- /usr/conf/master.d/krm
config failure.

I even tried replacing this file from the backups to see if it was corrupted in some way. Hasn't helped. Please advise.

(This version isn't supported.)

>error in opening file -- /usr/conf/master.d/krm

The file is there with the correct permissions on all of the component paths?

I know 11.00 isn't supported, but that's what I have & hence need to work on it.

I did check the permissions on the file path & compared it with a server with the same configurations & it's setup the same way. Following is how the permissions are:

drwxr-xr-x 25 bin bin 1024 Sep 9 02:43 /usr

dr-xr-xr-x 24 bin bin 1024 Sep 9 02:11 /usr/conf

dr-xr-xr-x 2 bin bin 2048 Sep 9 13:25 /usr/conf/master.d

-rw-r--r-- 1 root sys 956 Jul 12 2006 /usr/conf/master.d/krm

HP-UX fpkmgt01 B.11.00 U 9000/800 1820990626 unlimited-user license

The OS was installed with a March 2003 core OS CD & the March 2003 Support Tools pack was loaded after that.

It appears you may be having a problem with your EMS-KRMonitor kenerl modules.

1. Check if krm is installed:

# swlist -l product EMS-KRMonitor

# Initializing...

EMS-KRMonitor A.11.11.04 EMS Kernel Resource Monitor

2.# cd /etc/opt/resmon/lib/krm

# kminstall -a krm

This will put all the files in the correct location the files are:

subsystem code to /usr/conf/km.d/krm/mod.o

master file to /usr/conf/master.d/krm

system file to /stand/system.d/krm

3.Use kmsystem to check if the installation of the module was successful:

# kmsystem -q krm

Module Configured Loadable
=================================================

krm Y Y

4. Run # kmadmin -Q krm

to see what the status of the module is.... It should say "LOADED"

If the Module is not in the kernel you will need to rebuild the kernel and add the module:

# mk_kernel -M krm

NOTE: -->

Activated module(s) is(are) only available until system reboot.

# kmadmin -L krm

to load modules into a running kernel

kmadmin: Module krm loaded, ID = 1

If you are not using EMS just run

kminstall -d krm

This will remove the modules

Thank you for that! I re-searched & already tried that. It would still give me the same error at the 'mk_kernel -M krm' step. So I thought I'd try by just disabling this module altogether. I did a 'kminstall -d krm'.

Now, it gives the same error for other modules:

config: error in opening file -- /usr/conf/master.d/func0

So I think my problem is beyond just 'krm'. Something is screwed up on this system. Anything that doesn't need a kernel re-build, gets installed fine & wroks good. I am not even able to load any patches or modify any Static parameters.

What does 'swlist' return? Did you munge around in 'var/adm/sw' for any reason?

Or just that all of these changes need to do a kernel regen?

The kernel gen issue seems to be a symptom of a bigger issue.

You may want to review the 11.0 install procedures.

You mentioned replacing the krm file from backup , I am not sure of your back up tool or if the file was restored from an image from this systems backup of from another server. How and what you restored maybe the issue.

Not knowing the above makes it hard to pinpoint the true issue.

Cold Install the OS add the apps and then patch.

When patching be sure options are "manage patch selection" and "match what target has" are selected.

To minimize error use the TUI by running swinstall without options.

I tried restoring the 'krm' file from a Netbackup backup of the server. That didn't help. I had renamed the original file & have now put it back as 'krm'. I don't have the option of re-loading the OS now since the app is already up & running on it, but there are certain company standard products that I need to install & those need a kernel rebuild which is failing.
Nothing was done in /var/adm/sw
