How to access tape drive ?

[Liu Chung Him <eg_lchaa@stu.ust.hk>]

Dear all,

	I have a scsi tape drive and want to use it to backup. From the
output of dmesg, i know that the tape drive is detected. However, I don't
know the device file name of the drive. 

The output of "dmesg" command :

scsi : 1 host.
