hi
use
#dmesg | grep tape

[UVK]

I would also check #cat /proc/scsi/scsi; to find out if system is seeing any tape drives and them #mt -f status;

-uvk

Determining the SCSI id (Linux)


Check the output of dmesg to find out what SCSI channel number is used for each connection.

To find out the SCSI IDs in use on each channel, execute
# cat /proc/scsi/scsi


Output show...Attached devices:

Host: SCSI0 Channel:00 Id:00 Lun:00
Vendor: HP Model ------------
Type: Direct-Access ANSI SCSI Revision 02



To see the device drivers loaded currently, execute an lsmod command
#lsmod

Module Size Usedby

st 28434 0 (This is the tape driver which shows that the tape driver is loaded. )

ncr53c8xx 52333 1 (This is a SCSI chipset driver for the LSI Logic family of HBAs)

aic7xxx 12312 2 (This is a SCSI chipset driver for the Adaptec 7xxx chipset family)

Assuming a tape driver is present
any drives will have associated devices:

/dev/st0
/dev/st1..

E.g. to test if a tape drive is online:

mt -f /dev/st3 status 2> /dev/null 1> /dev/null
if test $? -ne 0
then
echo "Drive is offline"
