Solution
Determine if vCenter Server is reporting the host as not responding. If so, there is a networking problem,
an ESXi host agent failure, or a total cluster failure. After the condition is resolved, vSphere HA should
work correctly. If not, reconfigure vSphere HA on the host. Similarly, if vCenter Server reports the hosts
are responding but a host's state is Agent Unreachable, reconfigure vSphere HA on that host.
vSphere HA Agent is in the Uninitialized State
The vSphere HA agent on a host is in the Uninitialized state for a minute or more. User intervention might
be required to resolve this situation.
Problem
vSphere HA reports that an agent is in the Uninitialized state when the agent for the host is unable to
enter the run state and become the master host or to connect to the master host. Consequently, vSphere
HA is not able to monitor the virtual machines on the host and might not restart them after a failure.
Cause
A vSphere HA agent can be in the Uninitialized state for one or more reasons. This condition most often
indicates that the host does not have access to any datastores. Less frequently, this condition indicates
that the host does not have access to its local datastore on which vSphere HA caches state information,
the agent on the host is inaccessible, or the vSphere HA agent is unable to open required firewall ports. It
is also possible that the ESXi host agent has stopped.
Solution
Search the list of the host's events for recent occurrences of the event vSphere HA Agent for the
host has an error. This event indicates the reason for the host being in the uninitialized state. If the
condition exists because of a datastore problem, resolve whatever is preventing the host from accessing
the affected datastores. If the ESXi host agent has stopped, you must restart it. After the problem has
been resolved, if the agent does not return to an operational state, reconfigure vSphere HA on the host.
Note If the condition exists because of a firewall problem, check if there is another service on the host
that is using port 8182. If so, shut down that service, and reconfigure vSphere HA.
vSphere HA Agent is in the Initialization Error State
The vSphere HA agent on a host is in the Initialization Error state for a minute or more. User intervention
is required to resolve this situation.
Problem
vSphere HA reports that an agent is in the Initialization Error state when the last attempt to configure
vSphere HA for the host failed. vSphere HA does not monitor the virtual machines on such a host and
might not restart them after a failure.
