Cannot setup HP Storage Works Ultrium 448 Tape Drive on ESXI 4.1 for VM Access

I have a Dell Poweredge 2900 with a HP Storage Works Ultrium 448 Tape drive, connected via an dedicated Adaptec AHA-39320A controller.
I want to get the Tape Drive working in a P2V Windows 2003 Server I just converted successfully. It was working ok before the p2v, and  I reseated the cables when I was cleaning out the case during maintenance.
I installed Esxi 4.1 onto the same server hardware,and am running the new VM great, execpt for the Seagate Backup Exec, which I am trying to setup next.

In Esxi, Configuration > Storage Adapters I can see the controller AHA-39230A, with vmhba3, which has no devices showing, but in the PATH says vmhba2:C0:T3:L0  LUN0 and the status is DEAD (!) and as a test I moved the TapeDrive to vmhba3 and it showed the change - so I know its being detected.

However, Its not showing under CONFIGURATION > STORAGE - DEVICES and I dont know if it should be.

When I goto add a SCSI device to the VM using Edit settings , I add SCSI Device, It doesn't show up in the Connection - SCSI Device drop down list to add.

When I goto CONFIGURATION > ADVANCED SETTINGS, I am told Host does not support passthrough configuration.
