NetWare 3.12 doesn't recognize the Tape Drive that attaced to onboard SCSI channel

[Ayman Altounji]

We have acquired a ML370 with controller Raid, two 18.2 SCSI HDs and a DDS2 Tape drive.
The tape Can be seen both on P.O.S.T and with the system configuration utility.
The OS bootup successfully.
When I use the LIST DEVICES command, it return a Unbound Device Object.
I've installed Arcserve6, it fail to load and return an error EA000:Failed Host Adapter Initialization. ASPIBD.NLM reported a critical error.
We try to load the Arcserve utility,it fail to load also, by this command
LOAD SYS:ARCSERVE.6\UTILITY\SCSISCAN
We have apply both the lastest patches for NetWare 3.12
and Compaq Server NSSD V6.4
