Virtual TapeServer 6.04.02 Installation Guide

Creating Virtual Tape Drives

After Virtual TapeServer (VTS) is deployed, you must create virtual tape drives (VTDs). Up to

32 VTDs are supported per VTS server, and your VTD license determines how many VTDs

you can create. If you must modify a VTD after it is created, refer to the Virtual TapeServer

Operations and Administration Guide.

Creating a VTD

The following table describes the properties that you must set when defining the VTD. For

each property, this table provides a description and whether each property is presented to the

host server when VTS 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; the

host will see this bus numbered according to its numbering

scheme. 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 significance to the host.

Indirectly

Target ID The SCSI ID on which the VTD responds. This ID is not

presented to the host if the connection is over Fibre

Channel.

Yes, for

SCSI only

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 A unique identifier used by VTS to distinguish streams

originating from the same host.

Name A user-friendly name for the VTD. Yes

Media type The type of tape that the VTD emulates. Yes

Host type The type of host server. No

Serial number The serial number or other string describing the VTD. Only

alphanumeric characters should be used.

Yes
