Description

The Remove-SqlAvailabilityReplica cmdlet removes the secondary replica that is specified by the InputObject or Path parameters. This cmdlet must be executed at the server instance that hosts the primary replica.

Examples

Example 1: Remove an availability replica

PS C:\> Remove-SqlAvailabilityReplica -Path "SQLSERVER:\SQL\PrimaryServer\InstanceName\AvailabilityGroups\MainAg\AvailabilityReplicas\MainReplica"

This command removes the availability replica named MainReplica from the availability group named MainAg. This command must be run on the server instance that hosts the primary replica of the availability group.

Example 2: Generate a TransactSQL script that removes an availability replica

PS C:\> Remove-SqlAvailabilityReplica -Path "SQLSERVER:\SQL\PrimaryServer\InstanceName\AvailabilityGroups\MainAg\AvailabilityReplicas\MainReplica" -Script

This command outputs the Transact-SQL script that removes the availability replica named MainReplica from the availability group named MainAg. This command does not remove the replica.

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.

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf

-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.

-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
