Use the Remove-DatabaseAvailabilityGroup cmdlet to delete a database availability group (DAG). A DAG is a set of Mailbox servers that provide automatic database-level recovery from a database, server, or network failure. Before you can delete a DAG, you must first remove all servers from the DAG.


Remove-DatabaseAvailabilityGroup -Identity <DatabaseAvailabilityGroupIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

Detailed Description

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.


Parameter Required Type Description




The Identity parameter specifies the name of the DAG to be removed.




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
