kernel WARNING messages

Ken Englander — Tue, 20 Jan 2009 22:26:17 GMT

Does anyone know what is the significance of the following messages? They come up when kctune is run and I believe probably when some of the other kernel tools are run also.

WARNING: The file '/usr/conf/mod/ipf.bak' does not contain valid kernel
code. It will be ignored.
WARNING: The file '/usr/conf/mod/pfil.bak' does not contain valid kernel
code. It will be ignored.

How do I get rid of them and is it safe?

Thanks!

How did these *.bak files get there? Was it you or was it some kc* tool?

I suppose you can just ignore these warnings. Or you could create a subdirectory and move them there.

What does file(1) show for each? For IPF they should be:
/usr/conf/mod/ipf: ELF-64 relocatable object file - IA64

I do not know how this originally happened. It has been going on for some time and I finally decided to investigate it.

Both files appear to be valid. The file command shows them as " ELF-64 relocatable object file - IA64".

Note - I found these are the only .bak files in that directory.

What are the dates of ipf* and pfil*? Are they close?

Any copies of ipf and pfil in the IPD patch save area?
# find /var/adm/sw/save -path "*/usr/conf/mod/*"

I looked at the files and kc.log. It appears the error started showing up around the time I restored an Ignite backup while testing the 11.31 upgrade process.

I have renamed these files into the /usr/conf directory and the WARNING is no longer occurring. (It seems that kcmodule looks at ALL files in this folder regardless of their name.) There are existing files in /usr/conf/mod with these names without the ".bak" extension so I figured HP-UX did not care about these files especailly considering the error message.

There were no ipf or pfil files in /var/adm/sw/save.

Also, I could not find any documentation showing what are kept in /usr/conf/mod.

Thanks for your suggestions. I'm going to close this thread since I've effectively solved this problem.
