iSCSI connection not showing volume as mapped drive on my laptop

This question is not answered

Hi All,

I have three volumes(volSQL, volData, volLogs) that I replicated from a production SAN to a DR SAN. volSQL is essentially the C:\ drive on my SQL server. volData is the data drive and volLogs drive.

I cloned all 3 replications as volumes on the DR SAN and then made an iSCSI connection to each. Now I can see the volSQL and volDATA as mapped drives on My Computer but the volData doesn't appear. I can however see it in Disk Management(along with volData and volLogs).

Does anybody have any idea what the cause of this might be? volSQL is bootable? Could that somehow be the reason? The only other difference I noticed with it when compared with the other two was that the disk drives associated with volData and volLogs had a name assigned to them but volSQL didn't.

Any help would be appreciated.

Cheers

Paul

  • When you try to assign a drive letter to the volSQL, what error are you getting (popup, system log, etc.)?

  • I don't even have an option to assign a drive letter.

  • Ok, since the volSQL is a system disk (boot disk) you most likely will need to change one or both (attributes disk and/or attributes volume) listed here:

    technet.microsoft.com/.../cc732970(v=ws.10).aspx

    For the volume, you might have to do all 4 attributes (hidden | readonly | nodefaultdriveletter | shadowcopy)

    Do the detail disk and detail volume command first to see what needs to be changed.

    DISKPART>list disk

    DISKPART>list volume

    DISKPART> select disk #

    DISKPART>detail disk

    DISKPART> select volume #

    DISKPART> Detail volume

    Diskpart is a bit confusing, so follow the instruction on the link.  The link is part of the Diskpart commands that are available, to see the rest, just click the diskpart heading in the left tree structure.

  • Thanks for the reply DELL-Joe S.

    OK. I tried that.

    What I found is as follows:

    DISKPART> list disk

     Disk ###  Status         Size     Free     Dyn  Gpt

     --------  -------------  -------  -------  ---  ---

     Disk 0    Online          298 GB  1024 KB

     Disk 1    Online         2037 GB  1024 KB

     Disk 2    Online         1024 GB  2048 KB

     Disk 3    Online          500 GB  7168 KB

     Disk 4    Online         2037 GB  1024 KB

     Disk 5    Online         1536 GB  5120 KB

    The disks I am concerned with are Disk 2, Disk 3  and Disk 5

    Their details are:

    DISKPART>  select disk 2

    Disk 2 is now the selected disk.

    DISKPART> detail disk

    There are no volumes.

    For the volumes I found the following:

    DISKPART> list volume

     Volume ###  Ltr  Label        Fs     Type        Size     Status     Info

     ----------  ---  -----------  -----  ----------  -------  ---------  --------

     Volume 6         SAMSUNG_REC  NTFS   Partition     22 GB  Healthy    Hidden

     Volume 7     E   SQLDATA_New  NTFS   Partition   1024 GB  Healthy

     Volume 8     H   SQLLOGS_New  NTFS   Partition    500 GB  Healthy

    Disk 5 is the one I can't see in My Computer. It appears to have the same settings as Disk 2 and Disk 3 except that it doesn't have a volume. Could this be why I can't see it?

  • Check the following, in the EqualLogic Group manager: ensure that the clone is not set to “read only”.

    Then In DiskPart

    DISKPART>List disk

    DISKPART>Select disk 5

    DISKPART>List partition

    Do you see any partitions?

    Is you see the partition

    DISKPART>Select partition #

    DISKPART>Detail partition

    You should see the volume

    Once you see the volume you can assign it a drive letter
