.EXAMPLE This example shows how to ensure that the Availability Group 'TestAG' exists. In the event this is applied to a Failover Cluster Instance (FCI), the ProcessOnlyOnActiveNode property will tell the Test-TargetResource function to evaluate if any changes are needed if the node is actively hosting the SQL Server Instance. #> $ConfigurationData = @{ AllNodes = @( @{ NodeName = '*' SQLInstanceName = 'MSSQLSERVER' ProcessOnlyOnActiveNode = $true AutomatedBackupPreference = 'Primary' AvailabilityMode = 'SynchronousCommit' BackupPriority = 50 ConnectionModeInPrimaryRole = 'AllowAllConnections' ConnectionModeInSecondaryRole = 'AllowNoConnections' FailoverMode = 'Automatic' HealthCheckTimeout = 15000 BasicAvailabilityGroup = $False DatabaseHealthTrigger = $True DtcSupportEnabled = $True }, @{ NodeName = 'SP23-VM-SQL1' Role = 'PrimaryReplica' } ) } Configuration Example { param( [Parameter(Mandatory = $true)] [PSCredential] $SysAdminAccount ) Import-DscResource -ModuleName xSqlServer Node $AllNodes.NodeName { # Adding the required service account to allow the cluster to log into SQL xSQLServerLogin AddNTServiceClusSvc { Ensure = 'Present' Name = 'NT SERVICE\ClusSvc' LoginType = 'WindowsUser' SQLServer = $Node.NodeName SQLInstanceName = $Node.SQLInstanceName PsDscRunAsCredential = $SysAdminAccount } # Add the required permissions to the cluster service login xSQLServerPermission AddNTServiceClusSvcPermissions { DependsOn = '[xSQLServerLogin]AddNTServiceClusSvc' Ensure = 'Present' NodeName = $Node.NodeName InstanceName = $Node.SqlInstanceName Principal = 'NT SERVICE\ClusSvc' Permission = 'AlterAnyAvailabilityGroup', 'ViewServerState' PsDscRunAsCredential = $SysAdminAccount } # Create a DatabaseMirroring endpoint xSQLServerEndpoint HADREndpoint { EndPointName = 'HADR' Ensure = 'Present' Port = 5022 SQLServer = $Node.NodeName SQLInstanceName = $Node.SQLInstanceName PsDscRunAsCredential = $SysAdminAccount } if ( $Node.Role -eq 'PrimaryReplica' ) { # Create the availability group on the instance tagged as the primary replica xSQLServerAlwaysOnAvailabilityGroup AddTestAG { Ensure = 'Present' Name = 'TestAG' SQLInstanceName = $Node.SQLInstanceName SQLServer = $Node.NodeName ProcessOnlyOnActiveNode = $Node.ProcessOnlyOnActiveNode AutomatedBackupPreference = $Node.AutomatedBackupPreference AvailabilityMode = $Node.AvailabilityMode BackupPriority = $Node.BackupPriority ConnectionModeInPrimaryRole = $Node.ConnectionModeInPrimaryRole ConnectionModeInSecondaryRole = $Node.ConnectionModeInSecondaryRole FailoverMode = $Node.FailoverMode HealthCheckTimeout = $Node.HealthCheckTimeout # sql server 2016 or later only BasicAvailabilityGroup = $Node.BasicAvailabilityGroup DatabaseHealthTrigger = $Node.DatabaseHealthTrigger DtcSupportEnabled = $Node.DtcSupportEnabled DependsOn = '[xSQLServerEndpoint]HADREndpoint', '[xSQLServerPermission]AddNTServiceClusSvcPermissions' PsDscRunAsCredential = $SysAdminAccount } } } } |
