The easiest way I think to change kernel parameters is to go through SAM.

SAM->Kernel Configuration->Configurable Parameters

Modify the parameter and then SAM can rebuild the kernel and reboot your machine for you.

Hi Suresh,

10.X

1. Change directories to /stand/build.
# cd /stand/build

2. Create a new system file from the running kernel.
# /usr/lbin/sysadm/system_prep -s /stand/build/system

3. Edit the kernel with the planned changes.
# vi /stand/build/system

4. Build the new kernel.
# /usr/sbin/mk_kernel -s /stand/build/system

5. Move the old system and vmunix files so if anything goes wrong, the system
can be booted from the old kernel.
# mv /stand/system /stand/system.prev
# mv /stand/build/system /stand/system
# mv /stand/vmunix /stand/vmunix.prev
# mv /stand/build/vmunix_test /stand/vmunix

6. Reboot the system off the new kernel.
# shutdown -r -y now
