HP ProLiant DL380 Server - Manual (Page 13)

Creating an Emergency Boot Diskette
Creating an emergency boot diskette is highly recommended. If the server fails to
boot for some reason, the emergency boot diskette can be used to boot the server.
Complete the following procedures to create an emergency boot diskette:
NOTE: Have a 3.5-inch diskette available to serve as the emergency boot diskette.
1. Log on to the server as
root .
2. Enter the following command at the prompt, then press the Enter key:
ls /lib/modules
One directory appears for each available kernel.
3. Select the appropriate kernel version for the emergency boot diskette.
IMPORTANT: Do not use the SMP or Enterprise kernels for the emergency boot diskette.
4. Enter the following command at the prompt, then press the Enter key:
mkbootdisk --device /dev/fd0 (kernel)
where (kernel) is the available kernel selected in the previous step.
5. Insert the diskette into the diskette drive, then press the Enter key.
6. Remove the diskette when the message appears stating that the emergency boot
diskette has been successfully created.
7. Label the diskette as the Emergency Boot Diskette.
Powering Down the Server
The shutdown command must always be entered before powering down the server.
To immediately shut down the server:
1. Log on to the server as
root .
2. Enter the following command at the prompt, then press the Enter key:
shutdown –h now
