Sounds to me like the NTFS volume inside the LUN is set to Hidden and/or Readonly. There's an old Veritas bug that would cause this.
Look for a utility called "vflag.exe" from Microsoft. Mount the LUN manually and run "vflag -display *" and look for one marked hidden/readonly.
Use vflag to clear it. You can also use Diskpart.exe to do the same thing.

Hi,
Another question - I have a datawarehouse box - has 4 luns -> SD 6.1 and Server 2k8 both 64bit.
I can't seem to reconnect the LUN's using the SD wizard - however they do end up appearing in the Server Disk Management MMC.
Catch is they will only mount read-only (but at least the data is fine).
In iSCSI session management it will see the connected LUN's related to the igroup.
One of two things tends to happen - if I try to use SD I either get a 120 sec time out or I get an error about the lun already being mapped (presumably by the built in iSCSI initiator).
As per a previous post - this box was fine until a controller/ontap upgrade.
I've tried zapping the igroup and mappings on the SAN and removing all traces from SD and the MS iSCSI initiator but I can't seem to overcome this problem.
Any ideas ? Worst case I can carve off a whole new set of LUN's and move the data but I really don't want to have to do that if I don't have to.
Thanks in advance, Raj.
