"No disks were found on which to perform cluster validation tests" - why not?

    Question

  • I am new to clustering, and I'm trying to create my first cluster. I have two HP DL585 servers, each with a RAID configuration of RAID1 for the C: (system drive) and RAID6 for the Data drive. Both logical drives on each server are NTFS, and the two Data drives (the drives I am trying to cluster) are empty.
    When ever I try to run the validation test for Failover Cluster Manager between the two servers, I get an error saying "No disks were found on which to perform cluster validation tests".
    Why not? What do I need to do to the logical drives in order to allow them to be seen/accessed/used by Failover Cluster Manager?
    Any help gratefully received.

  • Have you verified that each disk has been assigned drive letter, formatted NTFS and has been presented to both nodes at the same time?  Present the disks to both nodes but only attempt to access and format them from one node until disks are added to cluster.

  • From your description, it sounds like your data drives are direct attached and not shared drives (iSCSI, Fibre Channel, or SAS).  In order for a drive to be seen by the cluster, it must be presented as a shared drive, i.e. directly accessible by both systems.

  • Ah, you mean that it can't be a "local" drive? What about it I were to 'share' the drives?

  • No.  What Tim is saying is that the disks must be based on SAN storage or iSCSI from which they can be zoned so that each node can the disk at the same time.  Using direct attached storage will not work.  You can use free target software and walkthrough this using VMs for example to get a better feel for what is needed from storage perspective or reach out to your storage vendor for assistance.  [Microsoft iSCSI Software Target 3.3]

  • While running cluster validation it keep throwing warning image
    Warning message says that "No Disks were found on which to perform cluster validation tests. To correct this,review that following possible causes:
    image
    Here it clearly says that disk should be offline when running this cluster validation test. After bring quorum disk offline and run the validation test and it went through.
    imageQuestion
    Understood. I think I had misunderstood how clustering worked (I think I was working along a "mirroring" model, rather than actual clustering). Thanks for clearing this up for me! :)
