4.7.1 Logical Drive Presentation after
Controller Failure
Figure 4- 10: Sample Configuration: Controller Failure
When a controller fails (as shown in Figure 4- 10), IDs presented
through the failed controller's host ports will fail over to the
surviving controller. These IDs will then be presented through the
existing FC links. See the diagram above.
Referring to the original configuration in the previous discussions,
ID presentation after a controller failure should look like this:
