Using Labeled and Unlabeled Tapes on
NonStop Himalaya K-Series Servers
You should use labeled tapes with the modular tape subsystem because they can be
cataloged and offer security features for protecting data. For an introduction to labeled
and unlabeled tapes, see Labeled and Unlabeled Tapes on page 1-5.
Using the MEDIACOM Utility for Labeled-Tape Operations
MEDIACOM is the utility for managing labeled-tape operations. MEDIACOM replaces
TAPECOM and provides the operator interface to the Distributed Systems
Management/Tape Catalog (DSM/TC). Use MEDIACOM commands to do the
following:
•
Label new tapes and catalog them
•
Handle tape mount requests
•
Manage the use of uncataloged tapes
•
Create scratch tapes
Refer to the DSM/Tape Catalog Operator Interface (MEDIACOM) Manual for more
information about using MEDIACOM.
How to Enable Labeled-Tape Processing
To use MEDIACOM, you must enable labeled-tape processing on your system. This is
done by specifying the following entry in the ALLPROCESSORS paragraph of the
CONFTEXT configuration file:
TAPE_LABEL_PROCESSING ENABLED;
This entry routes all tape requests through the tape server process, $ZSVR. If you do
not specify this entry, SYSGENR assumes that labeled-tape processing is disabled.
