This article describes an issue that occurs when cluster validation is run to validate cluster configuration in Windows Server 2012 R2. A hotfix is available to fix this issue. The hotfix has a prerequisite.

About this hotfix

This hotfix changes some timing of the "Validate Simultaneous failover" test to more accurately verify the storage compatibility with the failover cluster. This cluster validation test is intended to test and verify that the storage functionality is compatible with the failover cluster and other errors that are the test results. It will indicate an incompatibility that needs to be fixed.For more information about the support policy for the failover cluster, see: The Microsoft support policy for Windows Server 2012 or Windows Server 2012 R2 failover clusters.

Issue fixed in this hotfix

When you run failover cluster validation, the validation may fail during the storage validation tests. It may occur by using Validate a Configuration Wizard from Failover Cluster Manager or by initiating validation that uses the "Test-Cluster" PowerShell cmdlet.  The following is an example of the error message that may occur during this issue:

Validate Simultaneous FailoverDescription: Validate that disks can fail over simultaneously with data intact.Validate Simultaneous FailoverStart: Date and Time.Node machine1.domain.com holds the SCSI PR on Test Disk 0 but has failed in its attempt to bring the disk online.
