Configuring HyperFabric

Configuring HyperFabric with MC/ServiceGuard

Example 3:

This final example, illustrated by Figure 4-5 below, shows a situation in which all of the

HyperFabric adapters on node A fail. The HyperFabric Resource Monitor reports to the

Event Monitoring Service (EMS). The EMS then notifies the MC/ServiceGuard cmcld

daemon that the HyperFabric resource on node A is unavailable. Because HyperFabric is

configured as a package dependency for Packages A and B, MC/ServiceGuard causes the

packages to failover to node B. In a four-node configuration (note that only two nodes are

shown in Figure 4-5 below), Packages A and B can continue to communicate through the

HyperFabric network with the other active nodes in the MC/ServiceGuard cluster.

Configuring HyperFabric with the MC/ServiceGuard Resource Monitor

You can configure the HyperFabric Resource Monitor with MC/ServiceGuard in either of

these ways:

• Editing an ASCII file.

• Using the SAM GUI.

For more details, please see the manual Using EMS HA Monitors.
