Figure 13 When the path mode is Multi mode
Examples of switching I/O execution paths to alternate paths (when the path mode is Single mode)
Figure 14 (page 28) 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.
