Description

The New-SqlAvailabilityGroupListener cmdlet creates an availability group listener, and attaches it to an availability group. Run this cmdlet on the server instance that hosts the primary replica.

Examples

Example 1: Create a listener for an availability group

PS C:\> New-SqlAvailabilityGroupListener -Name "MainListener" -Path "SQLSERVER:\SQL\PrimaryServer\InstanceName\AvailabilityGroups\MainAG"

This command creates an availability group listener named 'MainListener' for the availability group named 'MainAG'. This listener acquires a virtual IP address by using DHCP. Run this command on the server instance that hosts the primary replica.

Example 2: Create a listener for an availability group that has a nondefault port

PS C:\> New-SqlAvailabilityGroupListener -Name "MainListener" -Path "SQLSERVER:\SQL\PrimaryServer\InstanceName\AvailabilityGroups\MainAG" -Port 1434

This command creates an availability group listener named 'MainListener' for the availability group named 'MainAG'. As in the previous example, this listener acquires a virtual IP address by using DHCP. This example assigns the port 1434 on which it listens.

Example 3: Create a listener for an availability group that uses DHCP

PS C:\> New-SqlAvailabilityGroupListener -Name "MainListener" -DhcpSubnet "192.169.0.1/255.255.252.0" -Path "SQLSERVER:\SQL\PrimaryServer\InstanceName\AvailabilityGroups\MainAG"

This command creates an availability group listener named 'MainListener' for the availability group named 'MainAG'. This listener acquires a virtual IP address in the specified subnet by using DHCP.

Example 4: Create a listener for an availability group that uses a static address

PS C:\> New-SqlAvailabilityGroupListener -Name "MainListener" -StaticIp "192.168.3.1/255.255.252.0" -Path "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAG"

This command creates an availability group listener named 'MainListener' for the availability group named 'MainAG'. This listener uses the IPv4 address specified by the StaticIp parameter as its virtual IP address.

Example 5: Create a script that creates a listener

PS C:\> New-SqlAvailabilityGroupListener -Name "MainListener" -Path "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAG" -Script

This command creates a Transact-SQL script that creates an availability group listener named 'MainListener' for the availability group named 'MainAG'. The command does not create a listener.

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.

This parameter is new in v22 of the module.

Type:PSObject
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-DhcpSubnet

Specifies an IPv4 address and subnet mask of a network. The listener determines the address on this network by using DHCP. Specify the address in for following format: 192.168.0.1/255.255.255.0.

If you specify this parameter, do not specify the StaticIp parameter.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Encrypt

The encryption type to use when connecting to SQL Server.

This value maps to the Encrypt property SqlConnectionEncryptOption on the SqlConnection object of the Microsoft.Data.SqlClient driver.

In v22 of the module, the default is Optional (for compatibility with v21). In v23+ of the module, the default value will be 'Mandatory', which may create a breaking change for existing scripts.

This parameter is new in v22 of the module.

Type:String
Accepted values:Mandatory, Optional, Strict
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-HostNameInCertificate

The host name to be used in validating the SQL Server TLS/SSL certificate. You must pass this parameter if your SQL Server instance is enabled for Force Encryption and you want to connect to an instance using hostname/shortname. If this parameter is omitted then passing the Fully Qualified Domain Name (FQDN) to -ServerInstance is necessary to connect to a SQL Server instance enabled for Force Encryption.

This parameter is new in v22 of the module.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-InputObject

Specifies the availability group, as an AvailabilityGroup object, to which this cmdlet attaches the listener.

Type:AvailabilityGroup
Position:2
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Name

Specifies a name for the listener.

Type:String
Position:1
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-Path

Specifies the path of the availability group to which this cmdlet attaches a listener. If you do not specify this parameter, this cmdlet uses current working location.

Type:String
Position:2
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Port

Specifies the port on which the listener listens for connections. The default port is TCP port 1433.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ProgressAction

Determines how PowerShell responds to progress updates generated by a script, cmdlet, or provider, such as the progress bars generated by the Write-Progress cmdlet. The Write-Progress cmdlet creates progress bars that show a command's status.

Type:ActionPreference
Aliases:proga
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Script

Indicates that this cmdlet returns a Transact-SQL script that performs the task that this cmdlet performs.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-StaticIp

Specifies an array of addresses. Each address entry is either an IPv4 address and subnet mask or an IPv6 address. The listener listens on the addresses that this parameter specifies.

If you specify this parameter, do not specify the DhcpSubnet parameter.

Type:String[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-TrustServerCertificate

Indicates whether the channel will be encrypted while bypassing walking the certificate chain to validate trust.

In v22 of the module, the default is $true (for compatibility with v21). In v23+ of the module, the default value will be '$false', which may create a breaking change for existing scripts.

This parameter is new in v22 of the module.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.
