For detailed information on the port block and setting the Initiator/External MIX mode, see the HP StorageWorks XP24000/XP20000 LUN Manager User Guide.

Figure 42 Difference between Standard Mode and Initiator/External MIX Mode

Figure 43 (page 124) shows an example of using XP Continuous Access or XP Continuous Access Journal with remote command device. The System 1 functions as MCU of XP Continuous Access or XP Continuous Access Journal, and at the same time it functions as the local storage system of the remote command device. The System 2 functions as RCU of XP Continuous Access or XP Continuous Access Journal, and at the same time it functions as the external storage system of the remote command device. In this case, the setting of XP Continuous Access pair or XP Continuous Access Journal pair and setting of the remote command device are both made using the port of the Initiator/External MIX mode. As this example shows, you only need to connect one cable to one of the ports that are set to the Initiator/External MIX mode, which means that you do not need to connect cables to each port of different port attributes.
