Blank iSCSI targets but targets still active

    Question

  • Hi All,
    I have a Windows server 2012 R2 core server running Hyper-v with iSCSI attachments. Many months ago I configured the iSCSI connections and everything was working fine. I recently went to add an additional connection however when i opened the iSCSI initiator interface i noticed under the 'Targets' tab the 'Discovered Targets' section was completely empty. The 'Discovery' tab had a portal pointing to our san, both the 'Favourite Targets' and 'Volumes & Devices' tabs were also blank.

    I attempted to use the quick connect to connect to our SAN to see if this might resolve the issue however i received the following in the progress report section:

    'The GUID passed was not recognized as valid by a WMI data provider.'

    All existing iSCSI disk attachments are still present and all VM's are working fine. I am at a loss as to where to go from here, any help would be greatly appreciated.

  • Hi Justdave,

    Did you make any changes before the issue happen?

    Have you tried to restart iSCSI Initiator Service?

    If possible, try to remove it and re-connect the target.

    Besides, authentication cache may cause connection failure, check the following path in registry:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\iSCSI\discovery

    Note: Please backup the key before modifying.

  • It's not an authentication issue, all the iSCSI targets are still connected. The iSCSI initiator is simply not displaying any of the connections.

  • Hi Justdave,

    I'm afraid I could not find muck information on the issue.

    If possible, recreate the targets to see if the issue still exists.

    Also check if the SAN is certified:

  • No sorry.

    My company has since upgraded away from our old SAN and since then we have had not issues. Sorry mate.
