kminstall error

[Catherine Forget]

Hi,
When doing : kminstal -u krm
I am getting the following error:
"kminstall:could not obtain the boot kernel path"

How can I resolve this?

Thanks for your help

[Mel Burslan]

from the man page of kminstall

When called with the -a or -u option, kminstall expects to find the
module's component files in the current directory, and installs or
updates copies of the files under subdirectories of the /usr/conf and
/stand directories.

were you in the same directory as the the module that you were trying to complie was ?

[Catherine Forget]

Hi Mel,
yes I was in the same directory.

[Mel Burslan]

does the output of dmesg command complain something about DLKM ?

[Catherine Forget]

yes I have a message : DKLM is not initialized. How do I initialized it?
I did the following but I get the same message:
#cd /stand/build
#/usr/lbin/sysadm/system_prep
-s /stand/build/system

#/usr/sbin/mk_kernel -s /stand/build/system
#mv /stand/system /stand/system.prev
#mv /stand/build/system /stand/system
#kmupdate /stand/build/vmunix_test
#shutdown -r

[Mel Burslan]

So, you actually reboot the system after the kmupdate or waiting for a resolution before rebooting it ?

If you already reboot the server, is the DLKM not initialized message still showing up in the syslog ? If you have not reboot yet and did all the steps that you listed above, you should be good to go with the reboot and DLKM not initialized message should not come after the machine comes back up.

Usually this message is related to not running kmupdate after rebuilding the kernel and reboot the server last time.

I would use SAM to rebuild a kernel and do a reboot if manual method is failing at this moment. It may give you some more insightful error messages if this is the case.

Kernel was not built properly.

echo "mod_inittialzed/D|adb -k /stand/vmunix

If it returns 0, then DLKM was not initialized.


Build the new kernel.
Backup /stand/vmunix
/stand/system
/stand/dlkm

cd /stand/build
Then system_prep -v -s ./system
kmtune/vi /stand/build/system

mk_kernel -s ./system -v
mv ./system /stand/system
kmupdate ./test_vmunix
cd /
shutdown -ry 0

Hi Anil,
The echo command returns : "symbol not found"
So, I think I have a bigger problem!

[Catherine Forget]

hi again,
the echo command is misspell. I added /dev/mem at the end and I got the return 0. The kmtune command is not good...

[RAC_1]

My typo mistake and completely forot to add /dev/kmem. It is as follows.

echo mod_initialized/D | /usr/bin/adb /stand/vmunix /dev/kmem

Did kernel rebuild resolve your problem?

[Navin Bhat_2]

If you did a cut and paste from Anil's message then you will have a problem since there is a spelling mistake.

echo "mod_initialized/D"|adb -k /stand/vmunix /dev/kmem
mod_initialized:
mod_initialized: 1

[Catherine Forget]

the kmtune still does not work, sorry.

[Navin Bhat_2]

kmtune -S /stand/build/system

Follow these exact steps. They will help.


# cd /stand/build

# /usr/lbin/sysadm/system_prep -s system

# mk_kernel -s ./system

# kmupdate /stand/build/vmunix_test

# shutdown -r 0

Your problem should be solved.

[Catherine Forget]

Thanks Navin. Now I get Unsatisfied symbole wsio_get_service.
I think I will need to reload the os on that server!

[Navin Bhat_2]

You dont need to reload the OS. Just follow the steps in the last two posts and you should be good to go.

nop! the boot stops after the hpux ... /stand/vmunix

Hi,

Looks like your current vmunix kernel is corrupted. Use a older / secondary kernel if you.

At the boot prompt,

bo pri
interact with ipl (Y/N) y
at the isl prompt,

type hpux -is (;)/stand/vmunix.old
if you want to boot into single user mode. Do not use "-is" if you don't want to boot into single user mode.

Hope this helps.
