Windows Server 2008 R2 Failover Cluster error / warning: SCSI 3 persistent reservation failed / CSV redirected access

Topic of this blog post is actually based around two possible errors/ warnings regarding Hyper-V cluster and Cluster Shared Volumes:

  • Cluster Validation Wizard:  Validate SCSI-3 Persistent Reservation    – Failed”
  • Unable to turn off Redirected Access on Cluster Shared Volumes (CSV)

Anyway both problems are influenced by one tiny configuration step in your storage vendor and can be solved with following steps (if your storage supports that):

  1. Log in to your storage vendor management console.
  2. Go to configuration of hosts connected to storage.
  3. There you will see one drop down menu where you can choose Microsoft Windows LH or Windows Server 2008 entry. If you have option for Windows Server 2008 choose that one and if you have option for Microsoft Windows LH choose that one.

By doing that you will resolve issue in validation wizard and also issue in Cluster Shared Volumes where you can’t turn off redirected access.

    where can one set host configuration to Microsoft Windows LH or Windows Server 2008 on NetApp storage? I can’t find it.

      I don’t really know exact procedure on NetApp storage. Maybe you can try to update firmware and try then. Or just try to contact your storage vendor and ask them if it is supported (Probably it is if your storage is newer). For example on some HP storage Windows LH also is not shown but you can choose custom field and then type following HEX number 00000004198009A8.

      Cheers
