Figure 8 When the Path Mode is Multi Mode
• When the path mode is Single mode
Figure 9 on page 27 shows an example of the case when the path mode is Single mode. When
an error occurs in the path that is being used for I/Os, the I/O execution path is switched to the
path with the second highest priority.
Note: As you restore the path with the priority higher than the currently used path, the I/O
execution path is automatically switched to the restored path that has the highest priority.
