Goal

SL8500 - ACSLS Support for Dual TCP/IP Connections.

Solution

Dual TCP/IP is an option that can be purchased for the SL8500. It provides two TCP/IP connections to the
SL8500. However, you can continue to use the SL8500 with only one of the two connections operational.
For more information on this feature, refer to the StreamLine SL8500 Modular Library System Dual TCP/IP
Feature document.
The purpose of dual TCP/IP is to automatically recognize and avoid a failing communication path. Since
this is automated, there is no need for you to manually switch from an inoperative connection.
In order to take full advantage of dual TCP/IP support on the SL8500, the routing tables on the ACSLS
server must be managed using the ârouteâ command. This forces a route to the defined network interfaces
on the SL8500 which in essence, creates a one to one relationship between interfaces. For further
information on the UNIX ârouteâ command, please refer to the manpages on your ACSLS server.

The ACSLS Administrator Guides, 8.0 and 7.3 show 5 different Dual TCP/IP connection scenarios in the "ACSLS Dual TCP/IP Support" sections of the "Installing Connections to Your Library Hardware" chapters. There are physical diagrams and route table examples for each.

The Dual TCP/IP configuration information for the SL8500 and SL3000 interfaces can be found in the SL Installation guides and more detailed information is contained in the Dual TCP/IP Technical Brief TT0019-Rev-C available at http://download-adc.oracle.com/archive/cd_ns/E21096_01/CRCM2359/CRCM2359.pdf
