Using Transact-SQL

To remove an availability group listener

  1. Connect to the server instance that hosts the primary replica.

  2. Use the ALTER AVAILABILITY GROUP statement, as follows:

    ALTER AVAILABILITY GROUP group_name REMOVE LISTENER ‘dns_name’

    where group_name is the name of the availability group and dns_name is the DNS name of the availability group listener.

    The following example deletes the listener of the AccountsAG availability group. The DNS name is AccountsAG_Listener.

    ALTER AVAILABILITY GROUP AccountsAG REMOVE LISTENER ‘AccountsAG_Listener’;

Using PowerShell

To remove an availability group listener

  1. Set default (cd) to the server instance that hosts the primary replica.

  2. Use the built in Remove-Item cmdlet to remove a listener. For example, the following command removes a listener named MyListener from an availability group named MyAg.

    Remove-Item ` 
SQLSERVER:\Sql\PrimaryServer\InstanceName\AvailabilityGroups\MyAg\AGListeners\MyListener

    [!UWAGA]

    To view the syntax of a cmdlet, use the Get-Help cmdlet in the SQL Server PowerShell environment. For more information, see Get Help SQL Server PowerShell.
