manually add tape drive in linux

Hi Guys..
Good day to all. This is my first time to install the OS, Red Hat. Anyway, the purpose of installing Linux is to see how tape drive works with this OS.
Now what i have done so far is to connect and install my scsi card but when i connected two different tape drives, the Linux system is not able to detect the tape drive.

By executing the command:

cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel:00 Id:00 Lun: 00
Vendor: Quantum Model: ATLAS IV 18 SCA Rev: 0808
Type: Direct-Access ANSI SCSI Revision:03

then when I tried:

lsmod | grep st ... it shows:

st 30768 0 (unused)
scsi_mod 107144 3 [st aic7xxx sd_mod]

so i think since the st driver is listed and my SCSI card is detected, i should not have a problem... but when i tried:

mt -f /dev/st0 status .. it resulted to:

/dev/st0: No such device

I tried from 0 until 6 but still no such device.

from constant research and forum search,

I tried to use the following commands:

modprobe st (to load st driver)
mknod /dev/st0 c 9 0 (to create a file /dev/st0)
insmod st.o (i think to invoke the st driver also)

and i also tried several commands from several resources but still cannot see my tape drive... I tried to use diff tape drive, LTO and DLT but same problem.. i really need to fix this issue today after working for several days now..

Thanks a lot for this forum and appreciate all insights.. :):):slight_smile:
