Exchange issues Powershell
Check the Database availability groups cmdlet - use to find out if exchange server is the Primary or Secondary
- Get-DatabaseAvailabilityGroup
You can get all the details you need by using the following command:
- Get-DatabaseAvailabilityGroup | fl
- Get-DatabaseAvailabilityGroup -status
Sometimes the witness will fail, you can check the status of the witness by using the cluster resource cmdlet:
- ipmo failoverclusters
- Get-ClusterResource
This will tell you where the witness stores the file. If the DAG finds the resource unrelibale it might mark it as failed - you can restart this by using start-cluster resource:
- Get-ClusterResource | Start-ClusterResource
Get the log for the cluster
- Get-ClusterLog -Destination <File pathway>
