performing a monitoring process on the network interface based on the virtualization zone type information, including performing, in a global zone, a network interface monitoring process when the network interface is in a local zone that does not otherwise make available or share information with the global zone, wherein the local zone and global zone are configured to be run by members of the cluster;

storing, on a first disk, zone data, IP data, and network interface controller data associated with a master node and a slave node within the local zone;

storing, on a second disk, the zone data, the IP data, and the network interface controller data associated with the master node and the slave node within the local zone; and

analyzing results of the monitoring process to determine the health of the network interface, wherein the monitoring process comprises:

checking the type of zone the network interface is assigned to; and

performing monitoring from the global zone if the network interface is assigned to a global zone.

8. The reprogrammable non-transitory computer readable medium of claim 7 wherein the network interface is included in an exclusive IP zone.
