Virtual TapeServer 6.04.01 Operations and Administration Guide

16 | Modifying Virtual Tape Drives
The first four properties are collectively referred to as the BTLI of the virtual tape drive. The
BTLI enables the host server to precisely identify the virtual tape connection; it provides an
exact address of the virtual tape’s location on the bus. Remember that the host is connected to
VTS by a single cable. The BTLI thereby enables you to multiplex the cable (for hosts
connected to VTS by a Fibre Channel cable), to identify multiple (virtual) tapes over a single
Fibre Channel cable.

To modify the properties of a virtual tape connection
1. Separate the virtual tape drive from its logical and physical counterparts. You cannot
reconfigure a virtual tape drive while it is connected to logical and physical drives.
On the System Overview page, the relationship between each virtual tape drive and the
logical and physical drives it emulates is shown:
For example, the $VTAPE01 virtual tape drive is associated with the LTAPE01 logical
drive and the PTAPE01 physical hard drive:
