Hi Amit,

1.) Procedure to generate a kernel at UX 11.00

1) Change to the kernel generation working directory and remove the files that have been left over from the last kernel generation:
# cd /stand/build
# rm -r * (Be careful with this! You need to be in /stand/build/)
2) Backup the current system file:
# cp /stand/system /stand/system.prev

7/33 Kernel Configuration Jan 2004
3) Is the system file up to date?
If you are not sure that the current system file (/stand/system) corresponds to the current kernel (/stand/vmunix), then use the system_prep script to extract a system file from the current kernel:
# /usr/lbin/sysadm/system_prep [-s /stand/system]
Compare the new system file to the original one. The diff command should not produce any results:
# diff /stand/system /stand/system.prev
4) Modify the system file
Use kmtune(1M) to modify kernel tunables. Use kmsystem(1M) to add/remove driver. These commands do nothing more than modifying /stand/system. Due to various dependencies, the system file should not be edited by hand. E.g.:
# kmtune -s shmmax= (changes tunable in system files)

5) Generate the kernel
After you modified the system file, you can generate the new kernel using the mk_kernel script. The name of the new kernel will be /stand/build/vmunix_test, unless explicitly specified through the -o option. The -s option specifies the system file to use, /stand/system is the default:
# mk_kernel
6) Schedule kernel update
kmupdate is used to initiate the move of the new kernel (/stand/build/vmunix_test) and the corresponding files to their appropriate places at the next shutdown or startup. The current kernel will be copied to /stand/vmunix.prev, then.
# kmupdate
7) Restart the system
The new kernel will be activated by restarting the system:
# cd /
# shutdown -ry now
