Restore from DVS Rescue USB - Venice 2u

Robert Leong -

DVS Rescue USB

Restore an OS image from the built-in USB stick.  As of around late 2012 the restore medium had been changed from DVD to USB drive, the USB drive is pre-installed inside the system.

This restore will erase everything on the destination device and replace it with the restored image.

This example was taken from a Venice 2u.

Boot from the Rescue USB

  1. Remove all Fibre Channel connections and any extra USB devices.

  2. Power up the computer and press DEL repeatedly to enter the BIOS setup.

  3. Goto the Save & Exit tab and locate the Boot Override section (lower left).  Highlight the USB drive to boot from.  Something like JetFlash... (this could be different if another USB vendor was used).  If this is listed under UEFI... do not select it, it will not work.  If can't find the proper USB then we have to do something else, see below at *1.  


*1 If Boot Override does not show the desired USB boot selection (again do not select the UEFI version), goto the Boot tab > Hard Drive BBS Priorities or Floppy Drive BBS Priorities > Boot Option #1 > select the boot USB as being 1st on the list.  This will allow the device to show up in the Boot Override selection menu.


Go back to the Save & Exit tab and the Boot Override should now show the new selection, select it to boot from it.


Your menu could be different but the idea is the same.

  1. In DVS Rescue Tools select DVS Rescue.


  2. Select 2 - Restore from internal USB device


  3. Enter "sda" for the System-Device is normally the default, but....

    In some systems with multiple RAID cards or multiple volumes on one RAID card, it is not clear which /dev to restore to, it is likely that the lowest numbered [x:x:x:x] values is the likely choice, but you might need to verify this by booting into the RAID card's BIOS to verify.


  4. Select the image listed, normally there is only one image but sometimes more, select the most recent version is a good default.


  5. Restore takes about 10 minutes, when complete select 3 to Reboot the system.

  6. The system should boot into the newly restored version.
