6.5.1

Problem
vSphere HA reports that an agent is in the Uninitialization Error state when vCenter Server is unable to
unconfigure the agent on the host during the Unconfigure HA task. An agent left in this state can interfere
with the operation of the cluster. For example, the agent on the host might elect itself as master host and
lock a datastore. Locking a datastore prevents the valid cluster master host from managing the virtual
machines with configuration files on that datastore.
Cause
This condition usually indicates that vCenter Server lost the connection to the host while the agent was
being unconfigured.
Solution
Add the host back to vCenter Server (version 5.0 or later). The host can be added as a stand-alone host
or added to any cluster.
vSphere HA Agent is in the Host Failed State
The vSphere HA agent on a host is in the Host Failed state. User intervention is required to resolve the
situation.
Problem
Usually, such reports indicate that a host has actually failed, but failure reports can sometimes be
incorrect. A failed host reduces the available capacity in the cluster and, in the case of an incorrect report,
prevents vSphere HA from protecting the virtual machines running on the host.
Cause
This host state is reported when the vSphere HA master host to which vCenter Server is connected is
unable to communicate with the host and with the heartbeat datastores that are in use for the host. Any
storage failure that makes the datastores inaccessible to hosts can cause this condition if accompanied
by a network failure.
Solution
Check for the noted failure conditions and resolve any that are found.
vSphere HA Agent is in the Network Partitioned State
The vSphere HA agent on a host is in the Network Partitioned state. User intervention might be required
to resolve this situation.
