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:
