Attachment to another Virtual Tape System
Images of virtual tape volumes can be exchanged directly with a tier party Virtual
tape unit. The transfer is possible only from the tier-party to the BackBox system,
i.e. for virtualizations.
Like the BackBox, other Virtual tape systems are able to materialize/virtualize. In
addition the BackBox VTC is able to provide to the other system a device that
appears as a physical tape drive. This link allows a tier-party Virtual tape unit to
materialize on a side and the VTC to virtualize on the other side.
To install this connection:
• In the VTC, among the target-mode tape controllers, one FC port is
dedicated for the emulation for Unix or Windows hosts, and one or
several tape drives must be configured on this port.
• A cable connects the VTC (target-mode tape controller) to the tier-
party Virtual tape unit (host tape controller).
• In the tier-party Virtual tape unit, the tape devices are configured in
the Operating System.
VTC configuration
• The VTC is configured by editing the BBFcEmulPortCfg.xml file and
restarting the FC Emulator service (NonStop devices attached to the
VTC should be stopped before the service is restarted).
• To access the file, open the Start menu and expand up to reach the
VTC Configuration folder (All Programs – BackPak – Virtual Tape
