Chapter 14: Configure Device Monitors 240

5. If there are no servers with completely healthy services, ClusterPulse

picks a server that has at least one service up and enabled. If

ClusterPulse finds a server meeting these conditions, it will use it,

preferring services earlier in the list of servers for this device monitor.

6. If ClusterPulse cannot locate a server meeting these conditions and the

monitor is configured with the Activity Type “Single-Always-Active,”

ClusterPulse will make the device monitor active on the first server in

the list of servers for this device monitor. If the Activity Type is

“Single-Active,” the device monitor will not be made active anywhere.
