Description

The Remove-SqlAvailabilityGroup cmdlet removes an availability group in Always On Availability Groups. You can run this cmdlet on any instance of SQL Server that has Always On Availability Groups enabled on a Windows Server Failover Cluster (WSFC) node that has security credentials for the availability group.

Examples

Example 1: Remove an availabity group

PS C:\> Remove-SqlAvailabilityGroup -Path "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups\MainAG"

This command removes the availability group named MainAG. You can run this command on any server instance that hosts an availability replica for the availability group.

Example 2: Remove all availability groups

PS C:\> Get-ChildItem "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups" | Remove-SqlAvailabilityGroup

This command gets all availability groups that have availability replicas in the specified location in the SQLSERVER: provider. The command passes them to the current cmdlet by using the pipeline operator. That cmdlet deletes each availability group.

Example 3: Create a script to remove an availability group

PS C:\> Remove-SqlAvailabilityGroup -Path "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups\MainAG" -Script

This command creates a Transact-SQL script that removes the availability group named MainAG. The command does not perform this action.

Parameters

-AccessToken

The access token used to authenticate to SQL Server, as an alternative to user/password or Windows Authentication.

This can be used, for example, to connect to SQL Azure DB and SQL Azure Managed Instance using a Service Principal or a Managed Identity.

The parameter to use can be either a string representing the token or a PSAccessToken object as returned by running Get-AzAccessToken -ResourceUrl https://database.windows.net.

This parameter is new in v22 of the module.

Type:PSObject
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Encrypt

The encryption type to use when connecting to SQL Server.

This value maps to the Encrypt property SqlConnectionEncryptOption on the SqlConnection object of the Microsoft.Data.SqlClient driver.

In v22 of the module, the default is Optional (for compatibility with v21). In v23+ of the module, the default value will be 'Mandatory', which may create a breaking change for existing scripts.

This parameter is new in v22 of the module.

Type:String
Accepted values:Mandatory, Optional, Strict
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-HostNameInCertificate

The host name to be used in validating the SQL Server TLS/SSL certificate. You must pass this parameter if your SQL Server instance is enabled for Force Encryption and you want to connect to an instance using hostname/shortname. If this parameter is omitted then passing the Fully Qualified Domain Name (FQDN) to -ServerInstance is necessary to connect to a SQL Server instance enabled for Force Encryption.

This parameter is new in v22 of the module.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-InputObject
