SCOM Failover Questions

Hi brentmattson,

The failover for the SCOM management servers happens automatically, so if management server 1 goes down, agents will automatically start communicating with management server 2, and management server 2 will start sending notifications.

However it works differently with gateway servers, you need to configure a failover gateway server for each agent, otherwise automatic failover will not happen.

How to set the primary and failover management / gateway server:

$PrimaryMS = Get-SCOMManagementServer | Where {$_.Name –match "MS1"} 
$FailoverMS = Get-SCOMManagementServer | Where {$_.Name –match "MS2"} 
$GatewayMS = Get-SCOMManagementServer | Where {$_.IsGateway -eq $True} 
Set-SCOMParentManagementServer -GatewayServer: $GatewayMS -PrimaryServer: $PrimaryMS 
Set-SCOMParentManagementServer -GatewayServer: $GatewayMS -FailoverServer: $FailoverMS

#Agents reporting to "Gateway 1" – Failover to "Gateway 2"

$PrimaryMS = Get-SCOMManagementServer | Where {$_.Name –eq "GW1"} 
$FailoverMS = Get-SCOMManagementServer | Where {$_.Name –eq "GW2"} 
$Agent = Get-SCOMAgent | Where {$_.PrimaryManagementServerName -eq "GW1"} 
Set-SCOMParentManagementServer -Agent: $Agent -PrimaryServer: $PrimaryMS 
Set-SCOMParentManagementServer -Agent: $Agent -FailoverServer: $FailoverMS

For the SCOM database and data warehouse, you should have a stretch cluster or use SQL Always On to provide high availability.

If you only have one SCOM database & data warehouse server, and it goes down, you will not receive any alerts.
