hyper-V Server Core 2008 R2 does not recognize EMC SAN drives

    Soru

  • Hi, I am looking at Hyper-V as an alternative to the other option, I have installed Hyper-V Server core on a server with 2 HBAs, configured the fiber switches made sure virtualization was enabled on the server, configured the EMC Clariion to connect to the host, created the storage goup, and the LUNS, they are connected to the host. Unfortunately the only drives I see through the management console are C: and D:. This is a standalone machine. What do I need to do to get this to recognize the EMC drives? Thanks in advance, Peter

  • Hello,

    Is Multipath IO feature installed?

    Also you can install EMC Powerpath for multipath drivers.

    Sincerely,

  • Which "management console" are you talking about when you say you can only see drives C: and D:?  Since Windows core does not have a console, I'm not sure what you are looking at.  Are you using RSAT from another system?  Or are you using Server Manager from another system? 

    MPIO is a feature that would need to be installed in the core system.

    You can run MPIO within a command window.

    MPIO -h will show you the storage devices that the MPIO DSM is claiming.

    You need to tell MPIO what it should be looking for.  Not sure if you mean EMC VNX when you say EMC Clariion, as that is what they named it to.  But, you should issue a series of MPIO  commands to let MPIO know what you are looking for from the array.  The VNX device ID is specific to the RAID type used in the RAID Group or Storage Pool.  It's recommended to add all these device strings to MPIO.  Note, there are exactly five (5) spaces after the DGC that must be included.

    DGC     DISK

    DGC     LUNZ

    DGC     RAID 0

    DGC     RAID 1

    DGC     RAID 10

    DGC     RAID 5

    DGC     VRAID

    The command to add the first id is:

    c:\> mpclaim -n -i -d "DGC     DISK"

    You should get a response of "Success, reboot required."  You don't have to reboot immediately.  You can add all the other device IDs and then reboot at the end.  But you have to let MPIO know what to look for.

    After the system reboots, enter:

    c:\> mpclaim -s -d

    You should now see a disk identified if you have your zoning and masking set correctly.

  • Thanks, I followed those steps and I can see the discs when I open disc manager on the management server, now I just have to get past the "RPC server is unavailable" error when I try to initialize them.  Peter

  • Hello,

    I've found that if I properly install the EMC drivers straight from EMC, similar to any other Windows Server, this works fine.  This would include PowerPath and any other drivers.  This is used by your SAN to gain visability into the systems communicating with it, as well as for providing connectivity from your server to the SAN.
