New-AzSqlDatabaseFailoverGroup

  • Reference
Module:
Az.Sql

This command creates a new Azure SQL Database Failover Group.

Syntax

New-AzSqlDatabaseFailoverGroup
   [-ServerName] <String>
   -FailoverGroupName <String>
   [-PartnerSubscriptionId <String>]
   [-PartnerResourceGroupName <String>]
   -PartnerServerName <String>
   [-FailoverPolicy <FailoverPolicy>]
   [-GracePeriodWithDataLossHours <Int32>]
   [-AllowReadOnlyFailoverToPrimary <AllowReadOnlyFailoverToPrimary>]
   [-PartnerServerList <System.Collections.Generic.List`1[System.String]>]
   [-ReadOnlyEndpointTargetServer <String>]
   [-ResourceGroupName] <String>
   [-DefaultProfile <IAzureContextContainer>]
   [<CommonParameters>]

Description

Creates a new Azure SQL Database Failover Group for the specified servers. Two Azure SQL Database TDS endpoints are created at FailoverGroupName.SqlDatabaseDnsSuffix (for example, FailoverGroupName.database.windows.net) and FailoverGroupName.secondary.SqlDatabaseDnsSuffix. These endpoints may be used to connect to the primary and secondary servers in the Failover Group, respectively. If the primary server is affected by an outage, automatic failover of the endpoints and databases will be triggered as dictated by the Failover Group's failover policy and grace period. Newly created Failover Groups do not contain any databases. To control the set of databases in a Failover Group, use the 'Add-AzSqlDatabaseToFailoverGroup' and 'Remove-AzSqlDatabaseFromFailoverGroup' cmdlets. Only values greater than or equal to 1 hour are supported for the '-GracePeriodWithDataLossHours' parameter.

[!NOTE] It's possible to deploy your auto-failover group across subscriptions by using the -PartnerSubscriptionId parameter in Azure Powershell starting with Az.SQL 3.11.0.

Examples

Example 1

$failoverGroup = New-AzSqlDatabaseFailoverGroup -ResourceGroupName rg -ServerName primaryserver -PartnerServerName secondaryserver -FailoverGroupName fg -FailoverPolicy Automatic -GracePeriodWithDataLossHours 1

This command creates a new Failover Group with failover policy 'Automatic' for two servers in the same resource group.

Example 2

$failoverGroup = New-AzSqlDatabaseFailoverGroup -ResourceGroupName rg1 -ServerName primaryserver -PartnerResourceGroupName rg2 -PartnerServerName secondaryserver1 -FailoverGroupName fg -FailoverPolicy Manual

This command creates a new Failover Group with failover policy 'Manual' for two servers in different resource groups.

Example 3

$sub2 = 'b3c40cd6-024f-428c-921b-cda6c6834c34'
$failoverGroup = New-AzSqlDatabaseFailoverGroup -ServerName primaryserver -FailoverGroupName fg -PartnerSubscriptionId $sub2 -PartnerResourceGroupName rg2 -PartnerServerName secondaryserver1 -FailoverPolicy Manual -ResourceGroupName rg1

FailoverGroupName                    : fg
Location                             : East US
ResourceGroupName                    : rg1
ServerName                           : primaryserver
PartnerLocation                      : West US 2
PartnerResourceGroupName             : rg2
PartnerServerName                    : secondaryserver1
ReplicationRole                      : Primary
ReplicationState                     : CATCH_UP
ReadWriteFailoverPolicy              : Manual
FailoverWithDataLossGracePeriodHours :
DatabaseNames                        : {}

This command creates a new Failover Group with failover policy 'Manual' for two servers in different subscriptions.
