If a particular driver module is not listed as above use the
modprobe
utility to load it. For example
if the
st
driver is missing, execute:
modprobe st
NOTE:
Loading of the
st
driver should happen naturally if your system is rebooted after attaching the drive.
Determining the attached devices
HBAs which use the
cciss
driver may require an explicit scan procedure to allow the attached tape
drive to be discovered after each reboot; execute the following from the command line (or from a
shell script):
for x in /proc/driver*/cciss/c*;do echo engage scsi > $x; done; dmesg
Check the contents of the file
/proc/scsi/scsi
to determine whether the system discovered the
tape drive at module load time:
cat /proc/scsi/scsi
Examine the contents for something like:
Host: SCSI0 Channel: 00 Id:00 Lun:00
Vendor: HP
Model: Ultrium 5-SCSI Rev: ZxxD
Type: Sequential-Access ANSI SCSI Revision 06
Look through the output of
dmesg
to discover which tape drive instance is used (
st0
in the example
below) and to review the SCSI HBA driver (
cciss
in the extract below).
NOTE:
The exact format and style of the listing may vary with different Linux distributions and versions.
TIP:
You may prefer to redirect a lengthy
dmesg
output to a file for browsing at your convenience:
dmseg > my_boot_messages.txt
or pipe the output of
dmesg
to a page scrolling utility
dmesg | more
Extract from
dmesg
output:
