kernel build - parameter re-specification kernel build aborted

Rick Garland — Tue, 07 Oct 2003 14:28:02 GMT

Hi all:

Got HPUX 11.11 on an L class system.
Needing to modify a couple of kernel parameters.
I am unable to SAM - keep getting a memory fault
Doing this the manual way. Did a system_prep -s Have modified the /stand/build/system and then doing the mkkernel -s command. The error response I get is:

config: Parameter re-specification
Configuration aborted

What is going on?

Eeek.

At this point, you might want to patch sam and get it working.

It would appear that you have with kumtune violated a formula in your changed kernel parameters.

Thats a good candidate.

There are two ways in building kernel in hpux11.11
1. kcweb
2. kmtune

1. In case of kcweb
- Install Apache depot (download from http://hpux.cs.utah.edu )
- stop apache demon.
- # kcweb -c ( with root authority )
- # kcweb -F
- If Kernel management Web is displayed, you can modify kernel.

2. In case of kmtune

- Display the status of kernel values.
#kmtune
- Modify kernel that you want
For example,
#kmtune -s shmmax=0x08000000
#kmtune -s nproc=2048
... and so on
- Backup the current kernal values.
#cp -p /stand/vmunix /stand/vmunix.org

- Compile the kernel.
#cd /stand/build
#mk_kernel
- update the kernel
#kmupdate /stand/build/vmunix_test
- Reboot the system.
#shutdown -ry 0

That's all...

Have a good day~~
Good luck~~

Rick,

the error "Parameter re-specification" means that a tunable is listed more than once in the system file. Usually the tunable in queston is printed just before the error message.

Check for duplicates using e.g.:
# sort -uk 1 /stand/system

Best regards...
Dietmar.
