.NAME
SqlAGListener .DESCRIPTION The `SqlAGListener` DSC resource is used to configure the listener for an Always On Availability Group. ## Requirements * Target machine must be running Windows Server 2012 or later. * Target machine must be running SQL Server Database Engine 2012 or later. * Target machine must have access to the SQLPS PowerShell module or the SqlServer PowerShell module. * Requires that the Cluster name Object (CNO) has been delegated the right _Create Computer Object_ in the organizational unit (OU) in which the Cluster Name Object (CNO) resides. ## Known issues All issues are not listed here, see [here for all open issues](https://github.com/dsccommunity/SqlServerDsc/issues?q=is%3Aissue+is%3Aopen+in%3Atitle+SqlAGListener). .PARAMETER InstanceName Key - String The SQL Server instance name of the primary replica. .PARAMETER ServerName Required - String The host name or fully qualified domain name (FQDN) of the primary replica. .PARAMETER Name Required - String The name of the availability group listener, max 15 characters. This name will be used as the Virtual Computer Object (VCO). .PARAMETER Ensure Write - String Allowed values: Present, Absent If the availability group listener should be present or absent. Default value is 'Present'. .PARAMETER AvailabilityGroup Key - String The name of the availability group to which the availability group listener is or will be connected. .PARAMETER IpAddress Write - StringArray The IP address used for the availability group listener, in the format '192.168.10.45/255.255.252.0'. If using DHCP, set to the first IP-address of the DHCP subnet, in the format '192.168.8.1/255.255.252.0'. Must be valid in the cluster-allowed IP range. .PARAMETER Port Write - UInt16 The port used for the availability group listener. .PARAMETER DHCP Write - Boolean If DHCP should be used for the availability group listener instead of static IP address. .EXAMPLE 1 This example will add an Availability Group listener with the same name as the cluster role VCO. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName 'SqlServerDsc' node localhost { SqlAGListener 'AvailabilityGroupListenerWithSameNameAsVCO' { Ensure = 'Present' ServerName = 'SQLNODE01.company.local' InstanceName = 'MSSQLSERVER' AvailabilityGroup = 'AG-01' Name = 'AG-01' IpAddress = '192.168.0.73/255.255.255.0' Port = 5301 PsDscRunAsCredential = $SqlAdministratorCredential } } } .EXAMPLE 2 This example will add an Availability Group listener with a different than the cluster role VCO. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName 'SqlServerDsc' node localhost { SqlAGListener 'AvailabilityGroupListenerWithDifferentNameAsVCO' { Ensure = 'Present' ServerName = 'SQLNODE01.company.local' InstanceName = 'MSSQLSERVER' AvailabilityGroup = 'AvailabilityGroup-01' Name = 'AG-01' IpAddress = '192.168.0.74/255.255.255.0' Port = 5302 PsDscRunAsCredential = $SqlAdministratorCredential } } } .EXAMPLE 3 This example will remove an Availability Group listener with a different name than cluster role VCO. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName 'SqlServerDsc' node localhost { SqlAGListener 'RemoveAvailabilityGroupListenerWithDifferentNameAsVCO' { Ensure = 'Absent' ServerName = 'SQLNODE01.company.local' InstanceName = 'MSSQLSERVER' AvailabilityGroup = 'AvailabilityGroup-01' Name = 'AG-01' PsDscRunAsCredential = $SqlAdministratorCredential } } } .EXAMPLE 4 This example will remove an Availability Group listener with the same name as the cluster role VCO. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName 'SqlServerDsc' node localhost { SqlAGListener 'RemoveAvailabilityGroupListenerWithSameNameAsVCO' { Ensure = 'Absent' ServerName = 'SQLNODE01.company.local' InstanceName = 'MSSQLSERVER' AvailabilityGroup = 'AG-01' Name = "AG-01" PsDscRunAsCredential = $SqlAdministratorCredential } } } .EXAMPLE 5 This example will add an Availability Group listener using DHCP on the default server subnet. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName 'SqlServerDsc' node localhost { SqlAGListener 'AvailabilityGroupListenerWithSameNameAsVCO' { Ensure = 'Present' ServerName = 'SQLNODE01.company.local' InstanceName = 'MSSQLSERVER' AvailabilityGroup = 'AG-01' Name = 'AG-01' <# If not specifying parameter DHCP, then the default will be DHCP with the default server subnet. #> DHCP = $true Port = 5301 PsDscRunAsCredential = $SqlAdministratorCredential } } } .EXAMPLE 6 This example will add an Availability Group listener using DHCP with a specific subnet. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName 'SqlServerDsc' node localhost { SqlAGListener 'AvailabilityGroupListenerWithSameNameAsVCO' { Ensure = 'Present' ServerName = 'SQLNODE01.company.local' InstanceName = 'MSSQLSERVER' AvailabilityGroup = 'AG-01' Name = 'AG-01' DHCP = $true IpAddress = '192.168.0.1/255.255.252.0' Port = 5301 PsDscRunAsCredential = $SqlAdministratorCredential } } } |
