9. Click OK. The change in the alternate path defined in the Path Setting window is applied to the local
array, and specified contents appear in the Device list.
If errors occur during alternate path operations, failed settings and error codes appear in the Preset list.
To check error messages, right-click the failed setting, and select Detail.
Canceling alternate path definitions
Use the Path Setting pane to cancel an alternate path definition.
1. Follow step 1 to step 3 in ”Defining alternate paths” on page 89.
2. In the Configured Paths table, right-click the row of the alternate path, and select Delete.
The selected alternate path’s definition is canceled, and detailed information about the path is deleted
from the Configured Paths table.
3. Follow step 6 to step 8 in ”Defining alternate paths” on page 89.
Changing alternate paths
To change an alternate path, cancel the current alternate path, and then define another path as a new
alternate path.
1. Follow step 1 to step 3 in ”Defining alternate paths” on page 89.
2. In the Configured Paths table, right-click the row of the path currently defined as the alternate path, and
select Delete.
The selected alternate path’s definition is canceled, and detailed information about the path is deleted
from the Configured Paths table.
3. In the Available Paths table, right-click the row of the path to be defined as the new alternate path, and
select Add.
The specified alternate path is defined, and detailed information about the path is displayed in the
Configured Paths table.
4. Follow step 6 to step 8 in ”Defining alternate paths” on page 89.
Adding alternate paths by selecting multiple external LUs (Add Paths)
To add paths other than the alternate paths you set when you mapped the volume, add paths at one time
by selecting multiple external LUs belonging to the same external LU group. To do this, set the alternate
path in the Add Paths window (Figure 53), check the setting in the Path Setting window (Figure 51), and
apply the setting to the array.
CAUTION: After adding paths using the Add Paths window, you can change the path setting for each
external LU in the Path Setting window. However, you cannot delete all current paths to completely
interchange them with the newly added paths. At least one current path setting must remain, even if you
added new paths using the Add Paths window.
