Virtual TapeServer 8.3 Configuration Guide

Creating and Managing VTLs and VTDs | 37

Validating access to VTDs from the NonStop server

To validate that the NonStop server can back up to configured VTDs in VTS, you must configure the

NonStop server to add the VTD. Then, you can start the virtual tape drive from the NonStop server.

Issue the following command on Integrity series servers to configure the virtual tape drive:

SCF ADD TAPE $VTD, SENDTO STORAGE, LOCATION (x,y,z), LUN #, SAC #, PORTNAME

WWN#, COMPRESSION OFF

where

$VTD — The virtual tape drive name, such as $TAPE00. The name specified here must match the

value specified when configuring the host device on the EMS Configuration page in the VTS web

interface.

LOCATION (x,y,z) — The location of the Fibre Channel ServerNet adapter (FCSA) in the Integrity

server, such as (110,3,2). This value depends on where the Fibre Channel cable is plugged into the

NonStop server.

LUN # — Where the virtual tape drive is defined on VTS. This parameter is specified for Fibre

Channel connections only.

SAC # — The Fibre Channel port on the FCSA. Valid values include 1-4. This parameter is specified for

Fibre Channel connections only.

PORTNAME WWN# — The World Wide Name (WWN) of the Fibre Channel port on VTS to which the

virtual tape drive is cabled. You can view the WWPN on the VTS web interface, on the Manage

Devices page. An example value is 210000E08B1AC519. Each Fibre Channel port has a unique WWN.

This parameter is specified for Fibre Channel connections only.

On NonStop S-series servers, issue the following command:

SCF ADD TAPE $VTD, BACKUPCPU #, COMPRESSION OFF, DENSITY 6250, DEVICEID

#, HIGHPIN ON, LOCATION (x,y,z), LUN 0, MAXOPENS 4, PRIMARYCPU

#, PROGRAM $SYSTEM.SYSTEM.OTPPROCP, RECSIZE 2048, SAC #, SENDTO STORAGE,

STARTSTATE STARTED

This command should return messages similar to the following if successful:

SCF - T9082G02 - (06JAN06) (31OCT05) - 01/19/2007 08:42:02 System \DEV3(C)

Total Errors = 0 Total Warnings = 0

Then, make sure no virtual tapes are mounted and start the virtual tape drive. To verify that no

virtual tapes are mounted, click Administration > Virtual Tapes on the navigation bar of the VTS

interface. Confirm that no virtual tapes are mounted.

To start the virtual tape drive, enter the following command on the NonStop server:

SCF START TAPE $VTD

This command should return messages similar to the following if successful:

SCF - T9082G02 - (06JAN06) (31OCT05) - 01/19/2007 08:42:11 System \DEV3(C)
