Add iSCSI storage to Cluster / VMM

    Question

  • Hello,

    I've a Hyper-V 2016 cluster with two nodes and also using VMM 2016.
    There is a storage spaces direct pool with cluster shared volumes.
    Now I want to add iSCSI storage to the cluster. This iSCSI storage is om a Linux server and I already have configured iSCSI initiators on both hosts. I can also see the disk within Disk Manager.

    But I can't see the disk in Cluster Manager and when I try to add the storage with VMM I can't add it as CSV. It seems I cannot create a Storage Pool.

    Does somebody has some tips? Am I missing some steps?

    Thanks

    Marcel

  • Hi!

    Can you see the disks showing as primordial in the Storage Console?

    Best regards,

  • Hello Leo, I am not sure what you mean with primordial and which storage console you mean.

    DISKPART> list disk

      Disk ###  Status         Size     Free     Dyn  Gpt
      --------  -------------  -------  -------  ---  ---
      Disk 0    Online          223 GB      0 B
      Disk 5    Online        1900 GB  1899 GB        *
      Disk 6    Reserved       1400 GB      0 B        *

  • Have you tried creating a partition and then add the disk to the cluster?

  • Hi

    I understand that the disk is visible in disk manager on both nodes but not on the cluster manager

    To add the disk to the cluster there are some more steps to be followed

    In the failover cluster manager console expand storage --> Add storage --> pop up windows will appear and the disk(s) will be listed. Select check box against the disk that are to be configured as the CSV. Now it will be visible on the failover cluster manager console

    Right click on the newly added disk (Available Disk) --> Add to cluster shared volume

    Now the said disks should show as cluster shared volume in FCM

  • Hello Bala,

    The disks does not appear within the Add Storage section, that is the problem.

  • As I mentioned earlier, try creating a partition, format the drives before that.

  • Hello Bala, I already had done that but the disk was not available. I removed the partition and tried again. Now I've formatted the disk, but still not available to add.

    Disk is visible at Physical Disks:

  • Try running the cluster validation wizard to see what it says, the wizard gives you the option to select which disks on which to run the tests, just select the disks you want to add.

    This help us to pinpoint any issues that may prevent you from adding the disks to the cluster.

  • Leon,

    I've done that:

    Disk partition style is GPT. Disk type is BASIC. The required inquiry data (SCSI page 83h VPD descriptor) was reported as not being supported.

    It seems I have to look at the iSCSI target configuration, do you agree?

  • Then there's the problem yes, double check the iSCSI target configuration.
