Enabling BMA Integration and Migration
Through integration with a backup management application server, you can read and write files to
and from Virtual TapeServer (VTS). You can then enable VTS to export, or “migrate”, virtual tapes to
physical tapes using an attached external tape device. On upgraded servers, you can configure the
hsm_ parameters in the configuration file to enable migration, which is described in this chapter.
Note You can also configure stacked export jobs if capacity is licensed, which is described in the
Configuration Guide.
To enable migration, you must install a backup management application (BMA) client on the VTS
server, which runs the Linux operating system. The BMA treats VTS as a UNIX host on the enterprise
network. Virtual tapes are then exported to the tape library managed by the BMA server according
to policies set by the BMA administrator. Refer to BMA documentation for instructions and more
information.
After installing and configuring the BMA, you must configure the Event Management Service (EMS)
on VTS. This is done using the VTS web interface. And you must configure the hsm_ parameters as
described in this chapter.
To automatically migrate tapes, you can configure the VTSPolicy command on the VTS server to
automatically export tapes. You can also manually initiate stacked exports by clicking the Migrate
button on the Virtual Media - Operation page. A BMA client must be installed and configured on the
VTS server to enable manual migration. You can use an external tape device attached during
installation, or you can attach a device as described in the Configuration Guide.
The BMA server can migrate virtual tapes using the following methods:
l The BMA administrator creates a backup job on the BMA server and schedules it to run on the
BMA client. The BMA server manages the entire process and maintains a database of the
backup files including a list of physical tapes to which the data was written. The BMA server
also controls the tape library.
If VTS deletes or erases a virtual tape, the BMA 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 BMA server from physical tape if the server requests access to a
virtual tape that was erased or deleted.
l VTS can request that the BMA server perform a backup or restore. This request is generated
when you manually initiate a migration. This request is issued using the BMA command-line
interface. VTS generates the BMA command request, executing it on the VTS server. The BMA
