I installed OpenServer 5.0.6 on a new System with EIDE Harddisk, IDE
CDROM and an HP DATStreamer on Adaptec 2940

The DAT drive is the only attached SCSI Deviceand is shown correct
on ID 3 from the Adaptec Bios functions.

each access to tape gets:

tape: unable to do 'status' command on '/dev/xct0' : No such device or
address

hwconfig -h shows:

adapter 0x5800-0x58ff 9 - type=alad ha=0 bus=0 id=7 fts=sto

hwconfig .scsi shows:

Whats wrong with this configuration ?
