102 Configuring external LUs
Restoring volumes in a mapped external LU individually
1. In LU Operation pane, select an external LU group number in the Device tree. Information about the
external LUs in the selected external LU group appear in the Device list.
2. In the Device list, right-click the external LU you want to restore, and select LDEV Restore.
The selected external LU group number and external LU appear in blue italics in the Device tree and
Device list. The contents of the setting appears in the Preset list. To check 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.
3. Click Apply. A confirmation message appears.
4. Click OK.
For the external LUs of the selected external array, the Status column of the Device list changes to the
restored status, and the external LU can be used in the Command View XP or XP Remote Web Console.
When errors occur during the status change for the external LU, the failed setting and error code
appears in the Preset list. To check the error message, right-click the failed setting, and select Detail.
Stopping the use of paths to an external LU by specifying an external
array’s WWN (Disconnect Paths)
To stop using the path between the local array and the external array by specifying the WWN that
identifies the external array’s port, select the WWN tree to display the WWN list.
NOTE: The Disconnect Paths command is not for the actual disconnection of the path to the external LU.
You must confirm that some normal paths to the external LU are set, other than the path for which you plan
to execute the Disconnect Paths command.
1. In the LU Operation pane, select the WWN tab. The WWN tree and WWN list appear.
2. In the WWN tree, select the product name of the connected external array. The WWN of all ports that
are connected to the local array and are used appear in the WWN list.
3. In the WWN list, select WWN you want to stop using. When you select the WWN identifying the
external array’s port in the list, you can stop the use of all ports of the local array connected to the port
at one time.
4. Right-click, and select Disconnect Paths. 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.
5. Click Apply. A confirmation message appears.
6. Click OK.
Restoring paths to an external LU by specifying an external array’s
WWN (Check Paths)
To restore the path between the local array and external array by specifying the WWN that identifies the
external array’s port, select the WWN tree to display the WWN list.
NOTE: The path must be in a status that can be restored.
1. In the LU Operation pane, select the WWN tab. The WWN tree and WWN list appear.
2. In the WWN tree, select the product name of the connected external array or the WWN identifying the
external array’s port.
• If you select the product name of the connected external array, all WWNs that are connected to the
local array and are used appear in the WWN list.
