# Enum - ClusterDasFdmAvailabilityState(vim.cluster.DasFdmAvailabilityState)

Since
  vSphere API 5.0

## Enum Description

The ClusterDasFdmAvailabilityState enumeration describes the availability states of hosts in a vSphere HA cluster. In the HA architecture, a agent called the Fault Domain Manager runs on each active host. These agents elect a master and the others become its slaves. The availability state assigned to a given host is determined from information reported by the Fault Domain Manager running on the host, by a Fault Domain Manager that has been elected master, and by vCenter Server. See ClusterDasFdmHostState for more information about the vSphere HA architecture.
