End-of-Volume
Processing
BIM-EPIC performs similar steps for end-of-volume (EOV) processing
as those performed for open processing. When performing EOV
processing, BIM-EPIC gains control and then passes control to VSE. To
perform EOV processing, BIM-EPIC carries out the following tasks:
BIM-EPIC releases the most recent drive assignment. If
Automatch is active, BIM-EPIC detaches the drive from the VSE
machine.
BIM-EPIC performs Automatic Volume Recognition (AVR) for
the next volume.
If BIM-EPIC cannot locate the next volume, it issues a message
to the operator.
When the tape is mounted on an available drive, BIM-EPIC
assigns and attaches the drive.
BIM-EPIC updates the DSN Catalog. On output, BIM-EPIC
writes another volume record for the version, places that volume
in open status, and places the previous volume into conditional
catalog status. On input, BIM-EPIC updates the date last
accessed, use count, and other statistical information.
BIM-EPIC passes final control to VSE.
Close
Processing
When BIM-EPIC is invoked for close processing, it passes instructions to
VSE for positioning the tape. In addition BIM-EPIC performs the
following tasks:
BIM-EPIC releases the drive assignments. If Autoattach is active,
BIM-EPIC detaches the drive from the VSE guest.
BIM-EPIC writes to the DSN Catalog, placing all volumes in a
closed status, if the version is an output version.
BIM-EPIC passes control to VSE.
Positioning options are: unload the tape, rewind the tape, or leave the tape
in place.
