4. To confirm that the physical tape device(s) was created and communicating in the
operating system, go to the Linux text console and enter the following command:
sg_map –x
Here is an example of the output from this command:
/dev/sg0 0 0 3 0 1 /dev/nst0
/dev/sg1 6 0 0 0 5 /dev/scd0
/dev/sg2 6 0 0 1 5 /dev/scd1
/dev/sg3 6 0 0 2 5 /dev/scd2
/dev/sg4 6 0 0 3 5 /dev/scd3
/dev/sg5 6 0 0 4 5 /dev/scd4
/dev/sg6 6 0 0 5 5 /dev/scd5
/dev/sg7 6 0 0 6 5 /dev/scd6
Then, find the nst0 entry (tape drive) attached and then enter this command:
sg_inq /dev/sgn
where sgn is the number that matches the /dev/nstn device. For the output listed above,
you would enter sg_inq /dev/sg0. Here is an example of the output from this command:
