CA Dynam for VSE User Guide

DYNCAT Commands
SERvice=
Optional parameter. Used only if the CA TLMS interface is active. Modifies the
status of the volume's service indicator.
IN
OUT
Changes the service indicator to inservice.
Changes the service indicator to out-of-service.
Note that an out-of-service tape is not allowed for output use. If an out-ofservice
tape is read as input, the service indicator is automatically changed to
inservice status.
Modifying File Sequence
To unchain all the datasets in a predefined multifile set, use the following
format:
ALTER 'data set name' UNCHAIN
UNCHAIN
All versions of all files in the multifile dataset will have their file sequence
updated to reflect the file sequence from the beginning of the tape the version
starts on.
UNCHAIN must be the only parameter specified on the ALTER command and it
must be specified for the first file in the predefined multifile dataset.
All datasets will no longer be predefined as multifile.
BACKUP Command
Use the BACKUP command to copy the contents of the CA Dynam Catalog to
tape or disk for security purposes. Use this command also to logically verify
the integrity of the Catalog so that, if an error has occurred, steps may be
taken immediately to correct it. You may run BACKUP with or without the
RECOVER operand.
The format of the command is shown below.
BACKUP [RECOVER]
[NODEQ ]
To create a normal backup file by using the Catalog directory for optimum
performance, specify BACKUP without an operand.
To create a backup file by sequentially reading the Catalog without accessing
the directory, specify BACKUP with the RECOVER operand. This file may later
be used to recover the contents of the Catalog if the directory has been
damaged.
