40 | Reconfiguring and Validating Virtual Tape Connections
Validating backups from the NonStop server to the VTS server
To validate that the NonStop server can back up to configured virtual tape drives in VTS, you
must configure the NonStop server to add the virtual tape drive. 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 assigned to the ems_hostdevs_NSserver parameter in the VTS
configuration file.
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, which is provided in the documentation shipped with VTS. 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) 1986 Tandem (C) 2006 Hewlett Packard Development Company, L.P.
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 Virtual Media 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
