How to Adjust the Disk Boot Sequence After a BMR Job on an Oracle VM Server

Valid on Oracle VM Server

Symptom

When I perform a BMR job to a target node on an Oracle VM Server, I get the following warning message in the Activity log:

The boot volume is restored to disk /dev/xxx. Please adjust the disk boot sequence in the BIOS to boot from /dev/xxx.

Solution

To avoid this problem, swap the disk boot sequence of the BMR target node.

Follow these steps:

  1. Edit the BMR target node from the Oracle VM Manager and click the Disks tab.

    Disks Tab in Oracle VM Manager

  2. Select Slot N disk as the Boot Disk.
  3. Make a note of the disk name and the slot number N.

    You will use the disk name and the slot number in the later steps.

  4. From the Actions column, select the Virtual Machine Disk button.
  5. Select the Leave Slot Empty option and click Save.

    Select Virtual Disk

  6. Select Slot 0 Disk and make a note of the disk name.
  7. From the Actions column, select the Virtual Machine Disk button.
  8. Select the Leave Slot Empty option and click Save.
  9. Attach the selected boot disk image to Slot 0 and the original Slot 0 Disk image to Slot N.

    Revised Disks Tab - Oracle VM Manager

  10. Boot the BMR target node.

The disk boot sequence is successfully adjusted.
