Virtual TapeServer 6.03.41 Installation Guide

84 | Enabling Enterprise Integration and Migration
If VTS deletes or erases a virtual tape, the BMA administrator must restore the virtual
tape, when necessary. If the NonStop server requests access to a virtual tape that was
erased or deleted, the mount request is queued on VTS until the data is recovered by the
BMA server from physical tape.
• 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 and sends it directly
to the BMA server. The BMA 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 NonStop server through EMS can initiate migration.
VTSPolicy can initiate many of the commands that are available on the BMA server. The
command can be scheduled on the NonStop server using NetBatch or appended to a
Tandem Advanced Command Language (TACL) backup script.
This chapter describes how to configure VTS for enterprise integration and migration. It also
includes information about adding a physical tape drive, which may be necessary for
migration. Refer to the Virtual TapeServer Operations and Administration Guide for
instructions to manually initiate migrating virtual tapes, encrypt data during migration, and
automate migration using the VTSPolicy command.
