You may see following warnings in the Validation report if the storage tests are skipped.
List Potential Cluster Disks
List disks visible to two or more nodes that will be validated for cluster compatibility. Online clustered disks will be excluded.
No disks were found on which to perform cluster validation tests. To correct this, review the following possible causes:
* The disks are already clustered and currently Online in the cluster. When testing a working cluster, ensure that the disks that you want to test are Offline in the cluster.
* The disks are unsuitable for clustering. Boot volumes, system volumes, disks used for paging or dump files, and disks that do not use NTFS are examples of disks unsuitable for clustering.
* The disks are not visible to two or more nodes. Review the "List All Disks" test to see which disks are visible to the nodes. Ensure that the disks you want to test are unmasked, that is, your masking or zoning does not prevent access to the disks. If the disks seem to be unmasked or zoned correctly but could not be tested, try restarting the servers before running the validation tests again.
* The cluster does not use shared storage. A cluster must use a hardware or software based replication solution to replicate data between nodes. If your solution is in fact based on replication between nodes, you do not need to rerun Storage tests. Instead, work with the provider of your replication solution to ensure that data is being replicated between nodes.
