Hi Guys
Thanks for the responses.
What I have found out so far is that the SCSI to Fibre Bridge we are
currently using (Compaq Fibre Channel Tape Controller II) does not allow
us to create persistent bindings.
We cannot implement persistent bindings from an HBA level as the DLT
drives do not have a WWN. 
The best we can do for now is bind the SCSI Bridge WWN to an HBA.
Does anyone know how else to implement persistent bindings from the
windows OS?
Thanks

Yes, but you can start there.  At the HBA level you can persistently
bind the WWN of the scsi-fiber bridge to a specific HBA "target".  You
shoud also be able to ask the bridge to persistently bind individual
SCSI targets on the bus to specific LUN addresses on the fabric side.

Those two settings, in combination with OS support, should be what you
need to keep things from moving around.
