Selecting wrong target device
For example, selecting the wrong target device can lead to a total
loss of data.
Do not execute any commands if you are not sure about the
correct source and target device.
To complete the loading of the
DVS Rescue
environment some user en-
tries are required. For this follow the instructions given on the screen.
The loading of the environment and the recovery process itself will both
try to initialize hardware that may not be present on your system. Any
error messages displayed during loading/initialization, e.g.
Failed
or
Warning
, can be disregarded. The recovery process should work none-
theless.
Please contact the R&S DVS service department if you are not sure
whether you are able to identify the correct target device.
