Figure 34 (page 84) shows the overview of the operation and the status of the cross-subsystem
paths. When you delete the current cross-subsystem paths (A and B) and add new cross-subsystem
paths (C and D), you cannot delete both the current cross-subsystem paths (A and B) in one operation
because at least one current path that functions normally has to be configured. In this case, you
need to delete the cross-subsystem path A and add the cross-subsystem path C, and then apply
the setting. After that, you need to delete the cross-subsystem path B and add the cross-subsystem
path D.
Figure 34 Overview of Operation to Replace All the Current Cross-subsystem Paths with Newly-added
Cross-subsystem Paths
To replace all the current cross-subsystem paths (A and B) with newly added cross-subsystem paths
(C and D):
1. Execute the Disconnect Paths command on the cross-subsystem path A.
2. Disconnect the cable that the cross-subsystem path A uses, and connect the cable that the
cross-subsystem path C uses.
3. Cancel the configuration of the cross-subsystem path A, and add the cross-subsystem path C.
4. Click Apply to apply the settings of the cross-subsystem paths A and C.
5. Make sure the status of the cross-subsystem path C is Normal.
At this point, the cross-subsystem paths B and C are configured as normal paths.
Take the following steps to delete the cross-subsystem path B and add the cross-subsystem
path D.
6. Execute the Disconnect Paths command on the cross-subsystem path B.
