Virtual TapeServer 6.03.42 Installation Guide

Reconfiguring and Validating Virtual Tape Connections

Virtual TapeServer (VTS) is preconfigured with virtual tape connections. Edit the virtual tape

connections, if necessary, to reflect exact connections between the hosts and virtual tape

drives in your environment. You can then validate that the host server(s) in the environment

can back up data to all virtual tape drives configured in VTS.

Modifying virtual tape connections

When modifying a virtual tape connection in VTS, you must define a virtual tape’s properties.

The following table describes the properties and specifies whether each property is presented

to the host server when the virtual tape responds to a host’s query:

Property Description

Presented

to Host?

Bus ID The ID of the bus on the VTS server to which the host is

connected. This ID is not presented directly to the host. If

the connection is over Fibre Channel, the bus ID is

associated with a port WWN that is used by the host to

identify the VTS server. If the connection is over SCSI, the

bus ID on the VTS server has no special significance to the

host.

Indirectly

Target ID The SCSI ID on which the virtual tape device responds.

This ID is meaningless to the host if the connection is over

Fibre Channel.

Yes

Logical unit

number (LUN)

The sub-ID on the bus. This ID is used by the host for SCSI

and Fibre Channel connections.

Yes

Initiator ID The SCSI ID of the host. This ID is meaningless to the host

if the connection is over Fibre Channel.

Yes

Name A user-friendly name for the virtual tape device Yes

Media type The type of tape drive that the virtual tape device emulates Yes

Host type The type of host (NonStop S-series server, NonStop

Integrity server, or UNIX server)

Serial number The serial number or other string describing the virtual

tape device

Yes
