Figure 7 Example of Unavailable Alternate Path Setting

Examples of Switching I/O Execution Paths to Alternate Paths

This section describes examples of the performance when the I/O execution path is switched to

the alternate path for each path mode as follows:

• When the path mode is Multi mode

• When the path mode is Single mode

• When the path mode is Single mode and there is at least one alternate path in the Standby

status

For the description about the path status, see “Mapping Path Information Dialog Box” (page 86).

• When the path mode is Multi mode

Figure 8 (page 22) shows an example of when the path mode is Multi mode. When an error

occurs in one path, I/Os are executed using the paths other than the error path.

As you restore the error path, the use of the restored path is automatically resumed.
