Switch-AzSqlDatabaseFailoverGroup

  • Reference
Module:
Az.Sql

Executes a failover of an Azure SQL Database Failover Group.

Syntax

Switch-AzSqlDatabaseFailoverGroup
      [-ServerName] <String>
      [[-FailoverGroupName] <String>]
      [-AllowDataLoss]
      [-TryPlannedBeforeForcedFailover]
      [-AsJob]
      [-ResourceGroupName] <String>
      [-DefaultProfile <IAzureContextContainer>]
      [-WhatIf]
      [-Confirm]
      [<CommonParameters>]

Description

This command swaps the roles of the servers in a Failover Group and switches all secondary databases to the primary role. All new TDS sessions are automatically re-routed to the secondary server after the DNS client cache is refreshed. When the original primary server is back online, all formerly primary databases in it will switch to the secondary role. The Failover Group's secondary server must be used to execute this command. If the AllowDataLoss parameter is not specified, this command waits until both roles are switched. If the AllowDataLoss parameter is specified, the command only waits until the new primary assumes its role.

Examples

Example 1

Get-AzSqlDatabaseFailoverGroup -ResourceGroupName rg -ServerName secondaryserver -FailoverGroupName fg | Switch-AzSqlDatabaseFailoverGroup -AllowDataLoss

Issue a failover operation allowing data loss by piping in the Failover Group.

Example 2

Switch-AzSqlDatabaseFailoverGroup -ResourceGroupName rg -ServerName secondaryserver -FailoverGroupName fg

Issue a best effort failover operation that will either succeed without losing data or fail and roll back.

Parameters

-AllowDataLoss

Complete the failover even if doing so may result in data loss. This will allow the failover to proceed even if a primary database is unavailable.
