The QLogic host bus adapters in one node must have the hard loop ID set to 125, and host bus adapters in the second node must be set to 124. The default setting for the hard loop ID on the QLogic card is 125, so you only need to change the hard loop IDs on one node.

To change the QLogic hard loop ID to 124 on one node from the default value, use the following procedure:

1.Start the node whose QLogic hard loop IDs you need to change.

2.Press <Alt><q> when the Press <Alt-Q> for Fast!UTIL message appears during the boot sequence.

3.In the Fast!UTIL utility, select the first adapter and press <Enter>.

4.Select Configuration Settings and press <Enter>.

5.Select Host Adapter Settings and press <Enter>.

6.Select Hard Loop ID and press <Enter>.
