Description

The Disable-SqlAlwaysOn cmdlet disables the Always On vailability groups feature on a SQL Server instance.

If the Always On 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 Always On 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.

Module requirements: version 21+ on PowerShell 5.1; version 22+ on PowerShell 7.x.

Examples

Example 1: Disable Always On Availability Groups at the specified path

PS C:\> Disable-SqlAlwaysOn -Path "SQLSERVER:\Sql\Computer\Instance"

This command disables Always On 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 Always On 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 Always On 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 Always On Availability Groups for the specified server instance

PS C:\> Disable-SqlAlwaysOn -ServerInstance "Computer\Instance"

This command disables Always On 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 Always On 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 Always On 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 Always On Availability Groups at the specified path without restarting the server

PS C:\> Disable-SqlAlwaysOn -Path "SQLSERVER:\Sql\Computer\Instance" -NoServiceRestart

This command disables Always On 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.
