Figure 2-3 Example of Alternate Path Setting
Figure 2-4 illustrates an example of setting an alternate path when a switch is
used. Two ports are specified in the local storage system, and connected to
the ports in the external storage system through the switch. In this case, two
ports of different clusters are specified in the local storage system. Therefore,
the setting of the alternate path is enabled.
