Utility Functions

While field-specific updates are possible, CA 1 provides the following special utility functions to reduce the amount of manual input required for common TMC update functions:

ADD

Marks an inactive (deleted) volume record as active.

CHECKIN

Checks in a tape that has been marked out-of-area.

CHECKOUT

Marks volumes out-of-area (CA 1 ISPF only).

CLEAN

Resets fields in the TMC to reflect that a tape has been cleaned (used when a tape is cleaned prior to being identified as needing cleaning by TMSCLEAN).

DELETE

Marks an active, scratch status volume record as inactive (deleted).

ERASE

Indicates volume has gone through physical degauss.

EXPIRE

Changes the expiration date to the current date.

EXTEND

Extends the expiration date for x number of days from the current expiration date.

LABEL

Generates an external tape label request for a volume.

RETAIN

Sets the expiration date to x number of days from the creation date.

SCRATCH

Scratches a volume set immediately.

Note: ERASE and SCRATCH are available only through the ISPF interface.
