104 Configuring external LUs
4. Right click, and select Change Parameter. The Change Parameter pane appears (Figure 59).
5. Change the selected port’s parameter.
6. Click OK. The Change Parameter pane closes, and the LU Operation pane appears. Selected items
appear in blue italics in the WWN tree and WWN list. The contents of the setting appears in the Preset
list.
To check the setting details, right-click the setting in the Preset list, and select Detail. To cancel the
setting, right-click the setting in the Preset list, and select Delete.
7. Click Apply. A confirmation message appears.
8. Click OK.
Stopping the use of paths to an external LU by specifying a local array’s
port (Disconnect Paths)
To stop using the path between the local array and external array by specifying the port of the local array,
select the Port Operation tree. The Port Operation list appears.
1. In the LU Operation pane, select the Port Operation tab. The Port Operation tree and Port Operation list
appear.
2. In the Port Operation tree, select External (the port attribute for the external array connection). The local
array’s external ports appear in the Port Operation list.
3. In the Port Operation list, right-click the port of the local array you want to stop using, and select
Disconnect Paths.
Selected items appear in blue italics in the Port tree and Port list. The contents of the setting appear in
the Preset list. To check the setting details, right-click the setting in the Preset list, and select Detail. To
cancel the setting, right-click the setting in the Preset list, and select Delete.
4. Click Apply. A confirmation message appears.
5. Click OK.
Restoring paths to an external LU by specifying a local array’s port
(Check Paths)
To restore the path between the local array and external array by specifying the local array’s port, select
the Port Operation tree. The Port Operation list appears.
NOTE: The path must be in a status that can be restored.
1. In the LU Operation pane, select the Port tab. The Port Operation tree and Port Operation list appear.
2. In the Port tree, select External (the port attribute for the external array connection) or the local array
port.
•If you select External, the local array port setting with the External attribute appears in the Port
Operation list.
• If you select the local array port, connection information about the path between the selected port
and external array appears.
3. In the Port Operation list, right-click the port of the local array for which you want to restore the path,
and select Check Paths.
Selected items appear in blue italics in the Port Operation tree and Port Operation list. The contents of
the setting appear in the Preset list. To check the setting details, right-click the setting in the Preset list,
and select Detail. To cancel the setting, right-click the setting in the Preset list, and select Delete.
4. Click Apply. A confirmation message appears.
5. Click OK.
Deleting external LU mappings (Delete LU)
You can start deleting external LU mappings from the LU Operation pane. To delete the external LU
mapping, select Delete LU from the shortcut menu displayed in the LU Operation pane. Although you can
