Administrative Network Failover An administrative network failure occurs when the interface on a particular server is no longer receiving HP Clustered File System administrative traffic. Some possible causes of the failure are a bad cable or network interface - HP ProLiant DL380G5-WSS | HP StorageWorks Clustered File System 3.6.1 Windows St - Page 72

The monitor remains active on the same set of servers. Device Monitor Activeness Policy ClusterPulse uses - HP ProLiant DL380G5-WSS | HP StorageWorks Clustered File System 3.6.1 Windows St - Page 251
monitor activeness policy decision is made as follows: 1. If the device monitor on a specific server is disabled, then the device monitor will not be made active on that server. 2. ClusterPulse considers the list of servers that are both up and enabled and that are configured for the device monitor - HP ProLiant DL380G5-WSS | HP StorageWorks Clustered File System 3.6.1 Windows St - Page 252

You can use the Probe Severity attribute to change this behavior.
