How HyperFabric Handles Adapter Failures
HyperFabric adapters are handled differently than other types of networking adapters
(such as Ethernet, FDDI, and Fibre Channel) in the MC/ServiceGuard environment. In
the non-HyperFabric cases, two network links are in a node, and one will be active and
one will be idle or in standby. In the case of an active link failure, MC/ServiceGuard is
notified and the network traffic is switched to the standby adapter (which then becomes
active).
However, in the case of HyperFabric, if two adapters are in a node, both will be active. If
one active HyperFabric adapter fails, its network traffic is switched to the other active
HyperFabric adapter in the node. (Throughput might be slower because only one active
