Resuming an Individual External Volume (Check Paths & Restore Volume)
To resume an individual external volume:
1. Start Remote Web Console, and open the Volume Operation window.
2. Make sure that Remote Web Console is in Modify mode.
3. Click the path group in the Volume Operation tree.
4. Right-click the external volume that you want to resume connection in the Volume Operation list.
A pop-up menu is displayed.

The settings are displayed in blue and italics.
6. Verify the settings in the Preview dialog box (see “ Preview Dialog Box ” on page 57).
7. Click Apply in the Volume Operation window.
The Ext. VOL Status in the Volume Operation window changes to Checking. When the checking
processing of mapping path status is completed, and the external volume can be resumed,
the Ext. VOL Status changes to Normal. If the external volume can not be resumed, the Ext.
VOL Status changes to Blockade.
Stopping the Use of Paths to the External Volume (Disconnect
Paths)
You use the Disconnect Paths command to prepare for stopping the use of the cross-subsystem path. For
example, when you want to maintain one of the cross-subsystem paths, you can stop the specified
cross-subsystem path while the local storage system is still connected to the external volume. To resume
the use of the cross-subsystem path which is stopped by the Disconnect Paths command, use the Check
Paths command (see “ Restoring the Paths to the External Volume (Check Paths) ” on page 93).
Note: The Disconnect Paths command is not for the actual disconnection of the cross-subsystem path to
the external volume. You need to confirm that some normal cross-subsystem paths to the external volume
is set, other than the cross-subsystem path for which you plan to execute the Disconnect Paths command.
To stop the use of the paths to the external volume:
1. Start Remote Web Console, and open the Path Operation window.
2. Make sure that Remote Web Console is in Modify mode.
3. Select one of the following from the drop-down list above the Path Operation tree.
• Fibre - Local Subsystem: Displays the ports in the local storage system. Select Fibre - Local
Subsystem to stop the use of all the cross-subsystem paths connected to the specified port in
the local storage system.
• Fibre - External Subsystem: Displays the WWNs in the external storage system. Select Fibre ­
External Subsystem to stop the use of all the cross-subsystem paths connected to the specified
WWNs (ports) in the external storage system.
4. Click Subsystem or the product name in the Path Operation tree.
5. Right-click the port or WWN that you want to stop the use of in the Path Operation list.
A pop-up menu is displayed.
6. Click Disconnect Paths in the pop-up menu.
The settings are displayed in blue and italics.
7. Verify the settings in the Preview dialog box (see “ Preview Dialog Box ” on page 57).
8. Click Apply in the Path Operation window.
The settings are applied to the local storage system and the Path Operation window is displayed
normally. When an error occurs, an error message is displayed. Verify the details in the
Preview dialog box.
