Recovery of the System Disk
The R&S DVS system provides internally a USB flash drive that
can be used to restore the operating system on the system SSD
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 SSD disk.
Perform the following steps:
1.
If appropriate, disconnect all Fibre Channel cables and all
externally connected storage devices from the system.
2.
Turn on or restart the R&S DVS system and at the indicated
moment during start-up press
[F11]
on your keyboard to
enter the boot menu.
3.
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 window on the screen where you can select the
R&S DVS Rescue environment for loading.
When completely inserted please observe that the latch
is truly in place and locking the unit.
Total Loss of Data
Selecting the wrong device can lead to a total loss
