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" -ScriptThis 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.
