5.5 Recovery of the System Disk
The DVS system provides internally a USB flash drive that can be used
to restore the operating system on the system hard disk back to its
manufacturing state. Once selected as a boot device, it will launch a
Live Linux which in turn will restore the system hard disk.
The following describes the steps to make a recovery of the system
hard disk:

If appropriate, disconnect all Fibre Channel cables and all externally
connected storage devices from the system.

Turn on or restart the DVS system and at the indicated moment dur-
ing start-up press [F11] on your keyboard to enter the boot menu.

Once the boot menu is displayed on the screen, select the internally
installed USB flash drive as the boot device and then press [Enter]
on your keyboard.
The system will now boot from the internal USB and you will see a win-
dow on the screen where you can select the DVS Rescue environment
for loading:

Select
DVS Rescue
and press [Enter] on your keyboard.
Once the loading has finished, you will see the DVS Rescue script with
its options on the screen. Your display should look similar to the follow-
ing:
--- DVS Rescue ---
1 - Backup on internal USB device
2 - Restore from internal USB device
3 - Reboot the system
4 - Poweroff the system
0 - Exit
Enter selection:
Do not execute any commands if you are not sure about the
correct target device. Selecting the wrong device can lead to
a total loss of data.
To complete the loading of the DVS Rescue environment some
user entries are required. For this follow the instructions given
on the screen.
The loading of the environment and the process itself will both
try to initialize hardware that may not be present on your sys-
tem. Any error messages displayed during loading/initializa-
tion, e.g.
Failed
or
Warning
, can be disregarded. The
backup/recovery process should work nonetheless.
