  • VMWare
  • Two VM’s on two separate VM Clusters
  • Shared VM Disks. (Basically not supported by VMWare)

During installation of MSSQL 2012 in Failover cluster, the installer stops at verification with error:

Rule „Microsoft Cluster Service (MSCS) cluster verification errors“ failed.
The cluster eighter has not been verified or there are errors or failures in the verification report. Refer to KB953748 or SQP Server Books Online for more information.

Well, the problem lies exactly where the error says:
Problem with cluster, not with MSSQL.

1. Check Failover cluster with Cluster Verification Tool
If there are no errors, the MSSQL Server installer should run without error now.

2. If the only error is with SCSI-3, then the cluster could not verify the VM disks.
Run the installer on Node 1 with:
Setup /SkipRules=Cluster_VerifyForErrors /Action=InstallFailoverCluster

After node 1 finished, run the installer on Node 2 with:
Setup /SkipRules=Cluster_VerifyForErrors /Action=AddNode
