I have installed AHA-2940UW Dual SCSI adapter and external HP SureStore DAT 24 Tape drive
on my linux box running RedHat 9.
On the next boot RedHat detected the new hardware.
When using RedHat Hardware browser I see it in the list of hardware devices :
SCSI devices:
---AHA-2940UW/AHA-38XX/AIC-7895
---AHA-2940UW/AHA-38XX/AIC-7895
-------------Manufecturer : Adaptec
-------------Driver: aic7xxx
Tape Drives:
---HP C1537A
-------------Manufecturer : Unknown
-------------Driver: none or buil-in
-------------Device : /dev/st
The problems - cannot access tape drive: Here are the commands and the error messages:
#mt status
#/dev/tape: No such file or directory
# mt -f /dev/st status
#/dev/st: No such file or directory
# mt -f /dev/st0 status
#/dev/st0: No such device or address
How can I check/prove if AHA 2940 driver is working properly ? Any ideas how to solve the problem and make the tape drive work?
Thank you for the help in advance! Milen ====================================================== P.S. I'm posting the ouput of lsmod and dmesg commands bellow:
