Exchange : Active Health Monitoring Inactive?
After applying update or patches on Exchange 2013 and bringing back to out of maintenance you notice that server components are still Inactive as shown below. In a situation like this you need to go extra mile to bring the server as is before maintenance. Below is the set of cmdlet when you put the server on maintenance where requester is calling for maintenance.
Set-ServerComponentState $Server -Component ServerWideOffline -State Active -Requester Maintenance
Set-ServerComponentState $Server -Component UMCallRouter -State Active -Requester Maintenance
Set-MailboxServer $Server -DatabaseCopyActivationDisabledAndMoveNow $False
Set-MailboxServer $Server -DatabaseCopyAutoActivationPolicy Unrestricted
Set-ServerComponentState $Server -Component HubTransport -State Active -Requester Maintenance
In addition to the single components which can be managed individually, there's also a component called "ServerWideOffline", which is used to manage the state of all components together, with the exception of "Monitoring" and "RecoveryActionsEnabled". For this purpose, "ServerWideOffline" overrides individual settings for all other components. It doesn't touch "Monitoring" and "RecoveryActionsEnabled" because these two components need to stay active in order to keep MA going. Without them, no "OnlineResponder" could bring "ServerWideOffline" back to "Active" automatically.
So the server is not 100% functional even though you took it out of maintenance. You will need to perform the following cmdlet to bring the server in ACTIVE State
Set-ServerComponentState -Component ServerWideOffline -State Active -Requester Functional
Set-ServerComponentState -Component Monitoring -State Active -Requester Functional
Set-ServerComponentState -Component RecoveryActionsEnabled -State Active -Requester Functional
You can also get the Get-ServerComponentState cmdlet from the Shell to retrieve these settings along with timestamp.
You can also use the script to bring the component state back to active state
