Shalom,

Most lsmod

cat /etc/redhat-release
uname -a

Check that the tape drive is not set to scsi-id zero. The scsi card needs that.

Don't hang it off the smart card scsi interface it won't work with that.

Hi Sir,

The Tape drive is internal.

On a Linux system, the scsi tape drives are accessed through /dev/st0, /dev/st1...

Just a test : insert a tape into the device, then try to read/write data on it :

cd /tmp
tar cvf /dev/st0 .
tar tvf /dev/st0

Note one important thing : the driver for the scsi card used for your tape device normally should be loaded automatically. If this is not the case, you may configure your system to do so :

=> edit /etc/modules.conf and add :

alias scsi_hostadapter aic7xxx

(replace aic7xxx by the driver that best matches your scsi card).

=> type "depmod" -a to check the kernel module dependency graph
