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..

tapeinfo
TAPEINFO(1) General Commands Manual TAPEINFO(1) NAME
tapeinfo - report SCSI tape device info SYNOPSIS
tapeinfo -f <scsi-generic-device> DESCRIPTION
The tapeinfo command reads various information from SCSI tape drives that is not generally available via most vendors' tape drivers. It issues raw commands directly to the tape drive, using either the operating system's SCSI generic device ( e.g. /dev/sg0 on Linux, /dev/pass0 on FreeBSD) or the raw SCSI I/O ioctl on a tape device on some operating systems. One good time to use 'tapeinfo' is immediately after a tape i/o operation has failed. On tape drives that support HP's 'tapealert' API, 'tapeinfo' will report a more exact description of what went wrong. Do be aware that 'tapeinfo' is not a substitute for your operating system's own 'mt' or similar tape driver control program. It is intended to supplement, not replace, programs like 'mt' that access your operating system's tape driver in order to report or set information. OPTIONS
The first argument, given following -f , is the SCSI generic device corresponding to your tape drive. Consult your operating system's doc- umentation for more information (for example, under Linux these are generally start at /dev/sg0 under FreeBSD these start at /dev/pass0). Under FreeBSD, 'camcontrol devlist' will tell you what SCSI devices you have, along with which 'pass' device controls them. Under Linux, "cat /proc/scsi/scsi" will tell you what SCSI devices you have. BUGS AND LIMITATIONS
This program has only been tested on Linux with a limited number of tape drives (HP DDS4, Seagate AIT). AVAILABILITY
tapeinfo is currently being maintained by Eric Lee Green <eric@badtux.org> formerly of Enhanced Software Technologies Inc. The 'mtx' home page is http://mtx.sourceforge.net and the actual code is currently available there and via CVS from http://sourceforge.net/projects/mtx/ . SEE ALSO
