HP XP20000, XP24000 manual Performing XP External Storage Operations

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

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.
