This behavior is an expected cosmetic issue. The alerts can be ignored and cleared once the HA configuration has finished resetting.
To avoid generating alerts, you can increase the monitor period (but this is usually unnecessary):
Notes:
Starting with vCenter Server 7.0 Update 1, the property name for fdm.policy.unknownStateMonitorPeriod has changed to fdm.unknownStateMonitorPeriod.
In vCenter, right-click the cluster and select Edit Settings.
Click vSphere HA and then Advanced Options.
Add a new option (if not already present)
Default Option is 10:
vCenter version |
Option |
Value |
---|---|---|
8.0 Update 2 onwards |
das.config.fdm.policy.unknownStateMonitorPeriod |
10 |
7.0 Update 1 to 8.0 Update1 |
das.config.fdm.unknownStateMonitorPeriod |
10 |
Pre-7.0 Update 1 |
das.config.fdm.policy.unknownStateMonitorPeriod |
10 |
For this issue, change the value from 10 to 30:
vCenter version |
Option |
Value |
8.0 Update 2 onwards |
das.config.fdm.policy.unknownStateMonitorPeriod |
30 |
7.0 Update 1 to 8.0 Update1 |
das.config.fdm.unknownStateMonitorPeriod |
30 |
Pre-7.0 Update 1 |
das.config.fdm.policy.unknownStateMonitorPeriod |
30 |
Disable and re-enable the HA settings of the cluster.
