kernel error

[Asya]

Hi everyone,

There seems to be a problem either with the forum or my login..but my search doesn't really work. I am sorry if this question was asked before...

I was installing patches for ipv6, but keep getting an error message while trying to rebuild kernel:

bash-2.05a# /usr/sbin/mk_kernel
WARNING: No such device, tunable, or cdio maxssize_64bit.
Ignoring the following line.
maxssize_64bit 83888608
Generating module: krm...

*** Error exit code 1

Stop.
config: make did an exit(1)


bstab exists...
bash-2.05a# which bstab
/usr/sbin/bstab

it's size is the same as it is on other servers where same patches worked fine.

What could be the reason?

Thank you!
Asya

Shalom Asya,

Rule number 1 of HP-UX administration.

NEVER change the root shell. Also don't do systems administration work in the bash shell.

Rule number 2 of HP-UX administration.

If you think you still want to change the root shell, re-read rule #1.

These utilties were designed to work with the posix/korn shell. Not bash.

Hi Steve,

Thank you...

well, i was getting this error while doing it with swinstall. I just saw the command there and tried to do it with sh -x to see what exactly was happening.

Exactly same error message i get in swinstall.

Thank you.

[Asya]

btw, same error message in ksh..

I suspect that you have manually edited the system file.
maxssize_64bit 83888608
should be:
maxssiz_64bit 83888608 and I would bump it up to about 32Mib or so
maxssiz_64bit 0x2000000

[Asya]

Hi Steve,

# kmtune |grep -i maxssiz
maxssiz 83888608 - 83888608
maxssiz_64bit 0x800000 - 0x00800000
# kmtune |grep -i maxssize
#


All is right it seems. I don't know where it's getting maxsize parameter from...

Hi Asya,

What is your OS version
what is your current kernel 32bit/64bit
can you attach your /stand/system file

Regards,
RD

[Asya]

OS: 11.11, 64 bit

Hmm..i see this in /stand/system

maxssize_64bit 83888608


How come it wasn't in kmtune info? Can i manually modify this file?

[A. Clay Stephenson]

Yes, you can. In fact I would bet that is how it got there in the first place (as I implied earlier). Use a text editor and simply delete the bogus entry.

[Asya]

Thanks..i will try.

No, i never modified that file by hand. At least not me....

[Don Morris_1]

Likely someone (or some application) modified the file directly. Yes, you can edit the file to remove that line, then use kmtune to set maxssiz_64bit as it should be done and repeat your mk_kernel.

[Asya]

I've modified the file and ran command with ksh..same thing, but no warning. Do i need to do anything else for it to work?

# /usr/sbin/mk_kernel
Generating module: krm...
Compiling /stand/build/conf.c...

Generating kernel symbol table...

Stop.

I didn't do anything with kmtune. I am not sure what to do with kmtune because all parameters were correct when looking at them through kmtune. Hope i'm making sense..

Thanks

I tried to do full reinstall...

[Asya]

Clay,

I am sorry I called you Steve...

[Asya]

oops...I made an old copy/paste. What was I trying to say..is that old WARNING disappeared...and the kmtune parameter.

Sorry for the confusion.

[Asya]

Sorry one more thing..

It seems that incorrect entry in /stand/system appears after installation of that particular fileset.

I modified the file, but after the install, incorrect entry is again there....
