Conﬁguring HMP for Transparent Local Failover Support

Chapter 4100

Case 2: Switch Failure (see Figure 4-8)

Consider the following illustration where node A is connected to node D

with trafﬁc being routed through the HF adapter 1 on both the nodes (A

and D), and the HF switch 1 fails. HMP transparently fails over trafﬁc

through the other available switch (HF switch 0). This is possible only if

at least one adapter of the card pairs on both the nodes (HF adapter 0 of

the Card Pair 0 on nodes A and D) is physically reachable (through the

HF switch 0).
