The Backup Job Fails to Collect the BMR-related Information or the BMR Job Fails to Create a Disk Layout

Valid on Oracle VM Server for HVM with LVM volume

Symptom

When I perform a backup job for an HVM with LVM volumes on an Oracle VM Server, the backup job fails to collect the BMR-related information. Also, when I perform a BMR job for an HVM with LVM volumes on an Oracle VM Server, the BMR job fails to create the disk layout.

Solution

To resolve this issue, disable the PV drivers for the backup source node.

Follow these steps:

1. Open the Command Prompt window on the backup source node and enter the following command:

   sfdisk -s
   

2. Verify if the same disk is displayed twice in the result.

   For example, xvdX and hdX are the same disk. Verify if both these disks are shown in the result.

3. If yes, then perform the following steps:
   1. Add the following line to the /etc/modprobe.d/blacklist file on the backup source node:

      blacklist xen_vbd
      

   2. Restart the backup source node and rerun the backup job.

      The backup job runs.

4. If no, then contact the Arcserve Support team.

The issue is resolved.
