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.

Select one of the following from the drop-down list above the Path
Operation tree.

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.

Operation list.
