To read the label on a tape, do the following:
1. If it is not already running, start the Tape Coordinator for the tape drive that you want to use with the operation. (See Starting a Tape Coordinator for information on using the butc command to start a Tape Coordinator.)
2. Verify that you are included in the appropriate administrative lists. If necessary, issue the bos lsadmin command to check.
3. Place the tape in the drive, and issue the bak readlabel command to read the label on the tape.
$ bak readlabel [-tcid tc_number]
