It is important to check the health of the Hyper-V hosts.

You can perform this tasks using powershell on the machine with Virtual Machine Manager powershell modules installed (Included with Microsoft SCVMM Console).

1 - Connect to the SCVMM server , example:

Get-SCVMMServer -ComputerName "SCVMMSERVER.DOMAIN.COM"

 2 - Check the health of Hyper-v hosts, example:

Get-SCVMHost | Select Name, OverallState

In environments with large number of hosts, you can filter the output, in the example beloe we check the hosts from one cluster only:

$Cluster = Get-SCVMHostCluster -Name "NAME OF THE CLUSTER"
Get-SCVMHost -VMHostCluster $Cluster | Select Name, OverallState

The expected state is "OK".

If you see the OverallState: "Needs Attention", this indicates that the host is not healthy.

3 - You can check Health Monitors and get more details. In the example below, we check the Health of hosts in the cluster:

$Cluster = Get-SCVMHostCluster -Name "NAME OF THE CLUSTER"
$Hosts = Get-SCVMHost -VMHostCluster $Cluster

foreach ($x in $Hosts) { $x.HealthMonitors }

You can see the state of monitor. In the example below, the agent version on the Hyper-v host required attention:

 

 

You can also perform similar health checks from SCVMM Console. You can select Hyper-V host in the console and select View State.

Example:

 

Usually PowerShell / Console show the recommended actions / remediation.

Problem Cause

All Hyper-V hosts were not healthy - there was Agent update pending .
