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.
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 Storage Navigator, and open the Path Operation window.
2. Make sure that Storage Navigator 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.
6. Click Disconnect Paths in the pop-up menu.
The settings are displayed in blue and italics.
