If you have RHEL 5, you can use the "lsscsi" command to see a listing of all SCSI and SCSI-like devices (FibreChannel, USB, Firewire, SATA...). It's very useful.
The "lsscsi" command is not installed by default; use "yum install lsscsi" if you don't have it installed yet.
With older versions, run "dmesg | less" to look at the kernel message buffer: when the kernel detects the tape drive, it prints out a message that includes the device name.
Most likely the "base" device name is /dev/st0. There is typically also /dev/nst0, the "no-auto-rewind" version of the device.
If you use /dev/st0, the tape is automatically rewound back to the beginning after each tape-access command is completed. Depending on what you're doing, you may or may not want that.
On the use of the tar command: use the command "man tar" to read the manual. The "tar" command has a *lot* of options.
