Use the EAC to remove a database availability group

Use the Shell to remove a database availability group

This example removes the DAG DAG1.

	Copy Code
Remove-DatabaseAvailabilityGroup -Identity DAG1

To verify that you've successfully removed the DAG, do one of the following:

• In the EAC, go to Servers > Database Availability Groups, and see if the DAG is still displayed.
  
  
• In the Shell, run the following command to see if the DAG still exists:
  
  

  	Copy Code
  Get-DatabaseAvailabilityGroup <DAGName>

  If the DAG was successfully deleted, the preceding command will produce an error message indicating the object could not be found.
