process and maintains a database of the backup files including a list of physical tapes to
which the data was written. The backup management application server also controls the
tape library.
If VTS deletes or erases a virtual tape, the backup management application administrator
must restore the virtual tape, when necessary. If Tivoli Storage Manager is used, the
mount request is queued on VTS until the data is recovered by the backup management
application server from physical tape if the server requests access to a virtual tape that
was erased or deleted.
• VTS can request that the backup management application server perform a backup or
restore. This request is generated when you manually initiate a migration. This request is
issued using the backup management application command-line interface. VTS generates
the backup management application command request, executing it on the VTS server.
The backup management application client will request services from the backup
management application server, which may be located on the VTS server or on a remote
server. The backup management application server then identifies the tape to back up or
restore and instructs the tape library to perform the operation.
• A VTSPolicy command sent from the host server through EMS can initiate migration.
VTSPolicy can initiate many of the commands that are available on the backup
management application server. The command can be scheduled on the host server using
NetBatch or appended to a Tandem Advanced Command Language (TACL) backup script.
Be sure that the backup management application client is installed and configured on the
VTS server. Refer to the backup management application documentation for more
information. Then, modify the VTS configuration file to configure migration, which entails
configuring the hsm_ parameters, and then set the username and password.
Note A default configuration file is defined for each VTS server. To override the default
settings, you must define settings as described below.
