Re: Configure kernel without SAM

Hi,

You can use

kctune

http://docs.hp.com/en/B2355-
60105/kctune.1M.html

kmtune

http://docs.hp.com/en/B2355-60105/kmtune.1M.html

to configure your kernel parameters.
you can view your current kernel configuration by "sysdef"

Re: Configure kernel without SAM

Hello,

These are the steps which will help you rebuild the kernel after changing any static kernel parameter. you change the parameter in step 5.

The kernel rebuilding process is accomplished using the following steps.
1. Change the directory to /stand/build.
2. cd /stand/build
3. Create the kernel parameter system file from the running system.
4. /usr/lbin/sysadm/system_prep -s system
91 of 244
5. Edit the system file to make necessary changes.
6. vi system
7. Build the new kernel using the mk_kernel command.
8. /usr/sbin/mk_kernel -s ./system
9. Back up the old kernel and system files.
10. mv /stand/system /stand/system.old
11. mv /stand/vmunix /stand/vmunix.old
12. Install the new kernel.
13. cp /stand/build/system /stand
14. cp /stand/build/vmunix_test /stand/vmunix
15. Reboot the system.
16. shutdown -r 0
17. Verify the changed parameters and additional devices using the following
commands.
18. sysdef
19. ioscan
You will see the presence of additional configured devices and any changes in
the system parameters.

Re: Configure kernel without SAM

Really easy:

cd /stand/build
/usr/lbin/sysadm/system_prep -s system
vi system (make your changes and save the file)
mk_kernel -s system
kmupdate
cd /
reboot your system

Re: Configure kernel without SAM

Shalom,

On 11.11 nfile is not dynamic, this requiring some combination of all steps above. Any perameter that kumtune reports as dynamic can be changed without the reboot, just a few simple kmtune commands
