Thread: Open-E DSS and Microsoft iSCSI Initiator

  1. #1

    Default Open-E DSS and Microsoft iSCSI Initiator

    Hi,

    I am trying to access an iSCSI Target on Open-E DSS. With a Windows 2003 Server and the MS iSCSI Initiator this is no problem. Trying to acces the target from a Windows 2000 Server this does not work correctly. I see the iSCSI Partition in the Windows Disk Manager, I can create and format Partitions, but I get an error "F:\ Das System kann das angegebene Gerät nicht finden" (means: "The system cannot find the given device.") when I try to open the new drive. There are no errors messages in the event viewer.
    I have tried nearly all versions of MS iSCSI Initiator between 1.06 and 2.08, but with all of them it's the same behaviour. I did not find anything to this error in the net.

    Thanks in advance for any hints

    I 've forgot: I tried the MS iSCSI Iniatiator on two different Windows 2000 Server Machines. There are no Firewalls/TCP-IP Filters installed.

    Was the iSCSI Volume created in Block IO or File IO ? Try File IO w/ Initialization. Is this on a separate Target and LUN from the Windows 2003 LUN?

    Hi nasenmann72

    Is your 2000 server updated to the latest service pack ?

    Here is a link for remote storage and some iSCSI issues:

    Hi,

    thanks for your replies!

    @To-M:
    Yes, the iSCSI volume is on a seperate Target and LUN. I've tried both Block IO and Try File IO w/ Initialization, but it ends in the same error.

    @To-L:
    Yes, the windows 2000 is up to date via Windows Update Services. The links you posted unfortunately did not fix the issue. But here are some additional infos:

    - the iSCSI volume is formatted with Windows 2000 version of NTFS
    - the iSCSI Initiator service is running
    - I additionally installed MS Remote Storage, but it did not recognise the iSCSI volume

    Here's a screenshot of the device manager which shows, that the iSCSI volume (F should be ok...

    Just a thought, try with a smaller size like 10GB. Also when at the format partition wizard in windows try to use the "Allocation unit size of 4096 (don’t use the default).
    All the best,

    To-L will try to find a Windows 2000 server and test, he hopes he has this and let us know.

    If anyone has a Windows 2000 server can you test this and let us know. It should work!
    All the best,

    Hi nasenmann72

    I just completed a fresh install of Windows Server 2000, I updated to service pack 4
    and downloaded the Microsoft iSCSI initiator-2.04-build3273-x86fre
    There are 3 different versions of the iSCSI initiator-2.04, do you have the correct one installed?
    It looks as it depends on the CPU.

    I was able to connect and mount to both a file I/O and Block I/O Lun
    I also copied files to both lun's.

    It looks as you did add the Lun to the target.
    Configuration-> iscsi target manager->target volume manager

    For the block I/O did you get message to format it first?

    I would double check your network, if possible make small network with only the DSS and the win 2000 server with a switch to test.

    Also check your NIC's could be a setting somewhere that is blocking you.

    Do you have any firewall applications on the Win 2000 server ?

    Also check for a firewall in you network.
