Description
The Disable-SqlAlwaysOn cmdlet disables the AlwaysOn vailability groups feature on a SQL Server instance. If the AlwaysOn availability groups feature is disabled while the SQL Server service is running, the database engine service must be restarted for the changes to complete. Unless you specify the Force parameter, the cmdlet prompts you to restart the service.
If the AlwaysOn availability groups feature is already disabled, this cmdlet makes no changes.
This cmdlet can run against a remote service.
You must have Administrator permissions to execute this cmdlet.
Examples
Example 1: Disable AlwaysOn availability groups at the specified path
PS C:\> Disable-SqlAlwaysOn -Path "SQLSERVER:\Sql\Computer\Instance"
This command disables AlwaysOn availability groups on the instance of SQL Server located at the specified path. This command requires restarting the server instance, and you will be prompted to confirm this restart.
Example 2: Disable AlwaysOn availability groups at the specified path and restart the server without confirmation
PS C:\> Disable-SqlAlwaysOn -Path "SQLSERVER:\Sql\Computer\Instance" -Force
This command disables AlwaysOn availability groups on the instance of SQL Server located at the specified path. The Force option causes the server instance to be restarted without prompting you for confirmation.
Example 3: Disable AlwaysOn availability groups for the specified server instance
PS C:\> Disable-SqlAlwaysOn -ServerInstance "Computer\Instance"
This command disables AlwaysOn availability groups on the instance of SQL Server named Computer\Instance. This command requires restarting the instance and you will be prompted to confirm this restart.
Example 4: Disable AlwaysOn availability groups for the specified server instance using Windows authentication
PS C:\> Disable-SqlAlwaysOn -ServerInstance "Computer\Instance" -Credential (Get-Credential "DOMAIN\Username")
This command disables AlwaysOn availability groups on the instance of SQL Server named Computer\Instance using Windows authentication. You will be prompted to enter the password for the specified account, DOMAIN\Username. This change requires restarting the instance and you will also be prompted to confirm this restart.
Example 5: Disable AlwaysOn availability groups at the specified path without restarting the server
PS C:\> Disable-SqlAlwaysOn -Path "SQLSERVER:\Sql\Computer\Instance" -NoServiceRestart
This command disables AlwaysOn availability groups on the instance of SQL Server located at the specified path, but the command does not restart the instance. The change will not take effect until you manually restart this server instance.
