Cluster Shared Volumes: How to mask/unmask disk??? RRS feed

All replies

  • The process varies according to the type of storage being used.  Basically it means that you make the storage invisible to the old cluster and visible to the new cluster.  Exact commands are dependent upon your storage - Fibre Channel, iSCSI, SMB, SAS, etc.

    Disconnect the storage from the old cluster or remove the storage from the old cluster.

  • Yes, I'm still waiting for the answer: how to mask LUN?

  • Can you offer some steps? How to do it in powershell/cmd?

  • Hi,

    How would you do it for iscsi and smb?

    Wednesday, November 27, 2019 4:52 PM
  • SMB - unmap the share.

    https://docs.microsoft.com/en-us/powershell/module/iscsi/disconnect-iscsitarget?view=win10-ps contains the Disconnect-IscsiTarget PowerShell documentation.

  • Thanks. I think this one is for ISCSI. For smb, maybe: Remove-SmbMapping?

  • Remember that you are dealing with a cluster resource.  If you read the documentation for Remove-SmbMapping you see that its purpose is to remove the mapping to a share.  In other words, it is removing the client access to the share.  You need to work from the server side to remove the cluster resource which contains the SMB share definition.  I would start with Remove-ClusterResource.

  • Ok. So what would be the exact steps 1-5?

  • It can be done from GUI or PowerShell.

    First step is to remove any file share resource defined to the cluster either via the cluster GUI or PowerShell.  If the CSV is defined on an SMB share coming from another server, you are ready to define the CSV to the new cluster.  If the CSV is defined on an iSCSI volume, after deleting the file share resource, you then use the GUI or PowerShell to remove the CSV from the cluster, making the disk just a cluster volume.  At this time you can disconnect the iSCSI target from each node of the cluster and present it to the nodes of the new cluster.
