Configuring a NearStore VTL Appliance to Use ACSLS

Configuring a NearStore VTL Appliance to Use ACSLS
	Chapter 2. Configuring a NearStore VTL Appliance

This section provides the introductory information that you need to configure a NearStore VTL appliance to use ACSLS-controlled tape libraries—that is, an ACS.

The NearStore VTL appliance can use an ACS. The ACSLS server and the VTL appliance communicate over TCP/IP, so before configuring the NearStore VTL to use ACSLS make sure the ACSLS server and the NearStore VTL appliance can communicate over network. The ACS tape drives communicate with the NearStore VTL appliance over the SAN, and so the SAN must be configured to permit this communication, for example, you might need to modify zoning. NetApp recommends that zoning be set so that the NearStore VTL only sees the specific drives it is going to be using.

The NearStore VTL appliance does not communicate directly with ACS robot arms.

In addition to the networking and SAN requirements, before using an ACSLS with a NearStore VTL appliance, you must set the Advanced Option Use ACSLS to control physical libraries.

Note

You can attach a SCSI library, or an ACSLS-controlled library to a NearStore VTL appliance, but not both. Before trying to configure the VTL appliance to use an ACSLS-controlled library, make sure that you do not have a SCSI library attached to the appliance.

Note

The VTL appliance discovers and controls the ACSLS library through the ACSLS server, so you must first specify the ACSLS server before configuring the VTL appliance to use the ACSLS library.

The NearStore VTL supports the ACSLS as a Backend Library Manager. The NearStore VTL presents the ACS to the backup applications, and so the backup applications only see the ACSs configured on the VTL. Typically this arrangement requires a SCSI jukebox license for the back up application.
