The normal operating state for a slave host. In this state,
the host is exchanging heartbeats with a master over
the management network, and is thus connected to it. If
there is a management network partition, the slave will be
in this state only if it is in the same partition as the master.
This state is reported by the master of a slave host.
The Fault Domain Manager on the host has been initialized and
the host is either waiting to join the existing master or
is participating in an election for a new master. This state
is reported by vCenter Server or by the host itself.
The Fault Domain Manager (FDM) on the host cannot be reached. This
state is reported in two unlikley situations.
- First, it is reported by
a master if the host responds to ICMP pings sent by the master over the
management network but the FDM on the host cannot be reached by the master.
This situation will occur if the FDM is unable to run or exit the
- Second, it is reported by vCenter Server if it cannot connect to a
master nor the FDM for the host. This situation would occur if all hosts
in the cluster failed but vCenter Server is still running. It may also
occur if all FDMs are unable to run or exit the uninitialized state.
The slave host appears to be down. This state is reported by the
master of a slave host.
An error occurred when initilizating the Fault Domain Manager
on a host due to a problem with installing the
agent or configuring it. This condition can often be cleared by
reconfiguring HA for the host. This state is reported by vCenter
The Fault Domain Manager on the host has been elected a
master. This state is reported by the the host itself.
A host is alive but is isolated from the management network.
See ClusterDasVmSettingsIsolationResponse for the criteria
used to determine whether a host is isolated.
A slave host is alive and has management network connectivity, but
the management network has been partitioned. This state is reported
by masters that are in a partition other than the one containing the
slave host; the master in the slave's partition will report the slave state
An error occurred when unconfiguring the Fault Domain Manager
running on a host. In order to clear this condition the host might
need to be reconnected to the cluster and reconfigured first.
This state is reported by vCenter
The Fault Domain Manager for the host has not yet been
initialized. Hence the host is not part of a vSphere HA
fault domain. This state is reported by vCenter Server or
by the host itself.
