Relabeling a Tape and Removing a Tape Label
Examples
This MEDIACOM example shows how to display brief format label information for an
IBM-MVS labeled tape that is mounted on the tape drive named $TAP06:
MC> INFO TAPELABELS, TAPEDRIVE $TAP06
Relabeling a Tape and Removing a Tape Label
When an application writes data to a tape, an expiration date is recorded on the tape.
When this date has passed, you can relabel the tape or remove the existing label.
To Relabel a Tape
1. Log on as a super-group user (255,n).
2. Write the intended label on the tape reel.
3. Enter this MEDIACOM command:
MC> ADD TAPELABEL old-tape-name, NEWNAME new-tape-name,
TAPEDRIVE $tape
new-tape-name is the name you want to use in the relabel operation.
4. Mount the tape on the selected tape drive.
5. Ready the drive and press Return.
When the relabeling process is complete, this message is displayed:
The relabeling operation changes the volume serial identification number of standard
labeled tapes.
Examples: Relabeling Standard Labeled Tapes

Caution. When you relabel or unlabel a tape, all existing data on that tape becomes
