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.
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 and encrypt data during migration.
This guide also describes how to automate migration using the VTSPolicy command.
