You may see output similar to: 

(scsi0)<Adaptec AHA-294XX Ultra2 SCSI host 
adapter> found at PCI 0/16/0

To find existing SCSI devices execute the command: 

You may see output similar to: 

Host: scsi0 Channel: 0 Id:6 Lun:00
Vendor: CERTANCE Model: ULTRIUM2
Type: SequentialAccess    ANSI SCSI
Revision 03

Use the output of these two commands to see which SCSI target id 

numbers are free. In the above example a tape drive is attached at target 

id 6. SCSI ID #7 is almost always dedicated to the SCSI controller. Never 

configure your target device for ID 7 unless you are absolutely sure that 

the controller is not addressed for ID 7.
The widely available distributions of Linux automatically install the 

proper SCSI and tape device drivers. If you executed the cat command 

above, you have ensured that the SCSI driver for your controller is 

installed. To view currently loaded modules, execute the 

 

command. Ensure that one of the entries is st. 
To view the st device number for your attached tape drive, execute the 

command: 

You should see output similar to: 

Detected SCSI tape st0 and scsi0 . . .

The LTO-2 Half-Height Tape Drive can be configured via the 

 

command options and a default configuration can be setup using the 

 command from within the mt command. See the man page 

for 

 for details. We suggest not using the erase command nor 

commands which attempt to partition the tape. Partitioning is not 

supported in the LTO format. 
For commands that use density and tape size settings, the tape density is 

124,000 bpi and the tape length is 1800 feet. For commands that use a 

blocking factor, we suggest a factor of 128.
