Consider the following scenario:
Notes
- You deploy a Windows Server 2012-based failover cluster. The cluster contains two nodes (node A and node B).
- A SCSI disk is used for the failover cluster. The disk is a shared disk and is accessible by both node A and node B.
- Node A restarts or crashes. Then, the cluster fails over to node B.
- Node A comes back online.
- Node B is shut down and the cluster fails over to node A.
- You write some data to the disk.
- The disk turns off unexpectedly. For example, the device losses power.
Notes
- This issue also occurs when the cluster contains more than two nodes.
- This issue does not occur if the SCSI disk supports the SCSI Primary Commands - 4 (SPC-4) standard.
