Figure 7 Example of Unavailable Alternate Path Setting

Examples of Switching I/O Execution Paths to Alternate Paths

This section describes the case 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 thepathmodeis Singlemode.

• 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” on page 84.

• When the path mode is Multi mode

Figure 8 on page 26 shows an example of the case 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.

Note:

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