Object operational state: healthy vs. unhealthy
The operation state of an object can be healthy or unhealthy, depending on the type
of failure and number of failures in the cluster. If a full mirror is still available, and
more than 50% of the object’s components are available in Virtual SAN 5.5, (or 50%
of the object’s votes are available in Virtual SAN 6.0), the object’s Operational State
is said to be healthy. If no full mirror is available, or less than 50% of the
components are available (possibly due to multiple failures in the cluster when the
VM is configured to tolerate 1 failure only), then the object’s operational state is said
to be unhealthy.
If we take the example that there were two failures in the cluster, the Compliance
Status remains at Not Compliant, the Operation Status changes to Unhealthy, and the
reason for the unhealthy state is displayed. In this example, the reason for the
“Unhealthy” Operations State is “disk unavailable” as shown below:
