Troubleshooting 7-19 G You can distribute eight LUNs across all four array controller ports. For example, assign LUNs 0 and 1 to array controller A port 1, LUNS 2 and 3 to array controller A port 2, LUNS 4 and 5 to array controller B port 1, and LUNs 6 and 7 to array controller B port 2. In this configuration, a single controller port can access all eight LUNs in the event of a path failure on the other three ports. I If you do install the optional Large LUN utility on your cluster, then you must follow these guidelines: G Do not assign unit offsets to any connections.
