52 Viper 200 Installation Manual
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. See figure 1 to view how
to set the SCSI ID address jumpers for the Viper 200.
The widely available distributions of Linux will automatically
install the proper SCSI and tape device drivers. If you
executed the cat command above you are already ensured
that the SCSI driver for your controller is installed. To view
currently loaded modules execute the command.
lsmod
Ensure that one of the entries is
st.
To view the st device number for your attached tape drive
execute the command:
dmesg | grep tape
You should see output similar to:
Detected SCSI tape st0 and scsi0 . . .
Using the Viper 200
The Viper 200 can be configured via the mt command options
and a default configuration can be setup using the
'stsetoptions' command from within the mt command. Refer
to the man page for mt 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.
