There should be a switch on the card, the one in the middle. It has a few positions. the documentation should point to this. If you want to go the hard set route, there is a jumper on the board that if enabled creates a "forced joined" config. Although this is mainly used for clustering an array.
Split-Bus Module
Your system supports three SCSI bus modes controlled by the split-bus module:
Cluster mode
Split-bus mode
Joined-bus mode
These modes are controlled by the position of the bus configuration switch when the system is turned on. Figure 1-6 illustrates the switch position for each mode.
Figure 1-6. Bus Configuration Switch Modes
The only difference between cluster mode and joined-bus mode is the SCSI ID occupied by the enclosure services processor. When cluster mode is detected, the processor SCSI ID changes from 6 to 15, allowing a second initiator to occupy SCSI ID 6. As a result, hard-drive slot 13 (normally occupying SCSI ID 15) is disabled, leaving 13 available hard-drive slots in cluster mode. For more information on SCSI ID assignments and cluster mode operation, see your Installation and Troubleshooting Guide. See Table 1-4 for a description of the split-bus module modes and functions.
NOTE: To change the SCSI bus mode, you must change the position of the bus configuration switch
before turning on the system. Using the bus configuration switch while the system is on will not affect system operation.
