Figure 5 Example of Alternate Path Setting
Figure 6
on page 24 illustrates an example of setting an alternate path when a switch is used. In
Figure 6 on page 24, 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.
Figure 6 Example of Available Alternate Path Setting
In Figure 7 on page 25, two paths are also set between the internal volume and the external volume.
However, one port is specified in the local storage system, and two ports are specified in the external
storage systems over the switch. This configuration is not recommended because two ports of different
clusters need to be set in the local storage system for alternate path settings in External Storage.
