16.3 Kernel Rebuilding in a Nutshell

   

---

The kernel rebuilding process is accomplished using the following steps.

1. Change the directory to /stand/build .

    cd /stand/build 

2. Create the kernel parameter system file from the running system.

    /usr/lbin/sysadm/system_prep -s system 

3. Edit the system file to make necessary changes.

    vi system 

4. Build the new kernel using the mk_kernel command.

    /usr/sbin/mk_kernel -s ./system 

5. Back up the old kernel and system files.

    mv /stand/system /stand/system.old mv /stand/vmunix /stand/vmunix.old 

6. Install the new kernel.

    cp /stand/build/system /stand cp /stand/build/vmunix_test /stand/vmunix 

7. Reboot the system.

    shutdown -r 0 

8. Verify the changed parameters and additional devices using the following commands.

    sysdef ioscan 

You will see the presence of additional configured devices and any changes in the system parameters.
