This technical brief describes the following topics:
• Proper shutdown procedure
• How to avoid data loss
• Recovery instructions in case of improper shutdown

It’s very important to do a proper shutdown of your HP Web hosting server appliances or you might
experience data corruption or even data loss. A proper shutdown consists of turning the unit off by pushing
the power button (“D” in the diagram below) until the unit shuts down. You may have to push down the
power button for several seconds while the unit goes through its shutdown sequence.


Additionally, to avoid data loss you should do one or all of the following:
• Always keep a backup of the Web Hosting Server Appliance data. This can be done using the Web
management interface.
• Install a second hard drive and set up a mirrored disk. Refer to the online help on your product or
go to http://www.hp.com/serverappliances/support for instructions on how to do this.

If the server appliance is improperly shut down and is subsequently unable to boot, follow this recovery
sequence:
1. While the appliance is powered on, connect a null modem serial cable (as found in the box) to the back
console port of the appliance.
2. Connect the other end of the serial cable to the serial port on a PC running Windows*.
3. Launch HyperTerminal, and set the port to communicate at 19200, n -8-1, Flow control - None. Press
Enter. You should see the appliance console, prompting you to enter the root password.
4. Reboot the appliance, and wait for the “LILO boot:” prompt. Press Tab within 5 seconds, which will
take you to the “boot:” prompt.
5. Type emergency and press Enter. This can takes a few minutes so be patient. Finally, t he login
prompt appears, and the LCD should be functional.
6. At the LCD, choose a random root password (password applies only to the emergency partition):
a.
If you don’t see menu choices, press the right arrow key until the menu appears.
b. Scroll to Defaults… and press the right arrow key to select it.
c.
Scroll to Root Password… and press the right arrow key to select it.
d. Scroll to Random and press the right arrow key. A randomly generated password appears.
e.
Record the password.
f.
Scroll to Yes and press the right arrow key to select it. The system applies the password
change immediately.
7. Going back to the HyperTerminal console session, log in to the appliance by entering root for the user
and then the randomly generated password. This will take you to a “#” prompt.
8. To fix the partitions, enter the following:
a.
For the sa1100, enter thes e commands in this order:
[…]#: fsck /dev/hda5
[…]#: fsck /dev/hda6
[…]#: fsck /dev/hda7
b. For the sa1120, enter these commands in this order:
[…]#: fsck /dev/sda5
[…]#: fsck /dev/sda6
[…]#: fsck /dev/sda7
When all of the partitions have been fixed, you will be returned to the “#” prompt.
9. Type reboot to reboot the system.
10. If the system still fails to start up, capture the output from the console and call technical support.
