Use the Get-DatabaseAvailabilityGroup cmdlet to obtain the list of servers that are members of a database availability group (DAG).
Syntax
Get-DatabaseAvailabilityGroup [-Identity
<DatabaseAvailabilityGroupIdParameter>] [-DomainController
<Fqdn>] [-Status <SwitchParameter>]
|
Detailed Description
In addition to obtaining a list of DAG members, the Get-DatabaseAvailabilityGroup cmdlet can also be used to view real-time status information about a DAG, such as:
- OperationalServers
- PrimaryActiveManager
- ReplicationPort
- NetworkNames
Use the Status parameter with the command to include the values for these properties. Without the Status parameter, the values returned for these properties are blank.
You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the"database availability group" entry in the High Availability Permissions topic.

Identity |
Optional |
Microsoft.Exchange.Configuration.Tasks.DatabaseAvailabilityGroupIdParameter |
The Identity parameter specifies the name of the DAG to query. |

Errors
| Error | Description |
|---|---|
|
Specified database availability group does not exist. |
Indicates that the specified DAG couldn't be found. Verify the DAG name and try the task again. |
|
Status is not available for the specified database availability group. |
Indicates that status couldn't be retrieved from Active Directory. Verify that connectivity with Active Directory exists and try the task again. |
|
Insufficient authority to perform the task. |
Indicates that you don't have permissions. Verify proper permissions are granted and try the task again. |
|
Windows Failover Clustering is not currently installed. This task cannot be run remotely without Windows Failover Clustering Tools (RSAT-Clustering). |
Indicates that status information can only be obtained for a DAG when this command is run from a server that has the Windows Cluster service installed. Try the task again from a server that has the Windows Cluster service installed. |
Examples
EXAMPLE 1
This example displays the list of servers in a DAG named DAG1. It also displays real-time status information for DAG1. In addition, several properties of the DAG, such as the file share witness directory and share configuration information are also displayed. The output for the command is formatted as a list.
