Scratching a Labeled Tape
•
If there is no error message, use the MEDIACOM STATUS TAPEDRIVE
command. If the drive is no longer “in use,” the application has been terminated
and you need not recover.
•
If you use a blank tape for a backup operation, the “unknown tape” message is
displayed. Accept the request to use that tape drive with the MEDIACOM ACCEPT
TAPEMOUNT command.
Scratching a Labeled Tape
A scratch tape is a labeled tape with an expired date. Because users often request
standard labeled scratch tapes for output, you might want to keep scratch tapes apart
from other tapes in your tape racks or tape library.
To create a scratch tape:
1. Log on as a super-group user (255, n ).
2. Enter this MEDIACOM command:
MC> ADD TAPELABEL ( tape-name [ , tape-name ] ) , SCRATCH
The ADD TAPELABEL command is not intended for tapes cataloged in a DSM/TC
system.
3. Mount the tape that has the specified vid on the selected tape drive.
4. Ready the drive and press Return.
Example
In this example, three tapes that contain unexpired files are changed to scratch tapes.
Each tape is mounted on the default tape drive for this session.
MC> ADD TAPELABEL (V11233, V11244, V20055), SCRATCH
When the ADD TAPELABEL, SCRATCH operation successfully ends, MEDIACOM
responds with a message such as:
Note. Before you scratch an unexpired labeled tape, check with your operations management
to ensure that this operation is allowed.
TAPE VOLUME V11233 SCRATCHED
TAPE VOLUME V11244 SCRATCHED
TAPE VOLUME V20055 SCRATCHED
