Symptoms

Consider the following scenario. You have a two-node failover cluster that is running Windows Server 2008. One of the disk resources is moved from one node to the other. In this scenario, a backup operation on the cluster may fail. When this issue occurs, the following events are logged in the Application log:

Event OneEvent TwoEvent Three

Cause

The backup operation fails because Automated System Recovery (ASR) unnecessarily returns an error for noncritical disks. The expected behavior is that ASR returns an error when critical disks are not available. ASR then logs a Warning event for noncritical disks. However, ASR returns errors when both critical disks and noncritical disks are not available.

Notes

  • Critical disks are disks that are required by the operating system, such as the disks that save the system volume and the boot volume.

  • Noncritical disks are disks that are used to store user data or application data.
