Description

The Add-NetworkControllerNode cmdlet adds a network controller node to an existing network controller deployment. If the existing computers in the deployment are not able to handle the load, this cmdlet can be used to scale up an existing deployment. A two node deployment is not supported. Therefore, if you are on a single node cluster and want to scale up, you must add at least two nodes to gain the benefits of high availability.

Examples

Example 1: Add network controller to an existing network controller deployment

PS C:\> Add-NetworkControllerNode -Name "Node1" -Server "NCNode1.contoso.com" -FaultDomain "fd:/rack1/host1" -RestInterface "Ethernet"                      
Name            : Node1
Server          : NCNode1.contoso.com
FaultDomain     : fd:/rack1/host1
RestInterface   : Ethernet
NodeCertificate : 
Status          : Up

This command adds a network controller node named Node1 to the existing network controller deployment. The FQDN of the computer is named NCNode1.contoso.com and the interface on the computer listening to REST requests is named Ethernet.

Parameters

-CertificateThumbprint

Specifies the digital public key X.509 certificate of a user account that has permission to perform this action. Specify this parameter only if you run this cmdlet on a computer that is not part of the network controller cluster.

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

-ComputerName

Specifies the name of the network controller node on which this cmdlet operates.

Type:	String
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

-Credential

Specifies a user credential that has permission to perform this action. The default is the current user. Specify this parameter only if you run this cmdlet on a computer that is not part of the network controller cluster.

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

-FaultDomain

Specifies the servers that are likely to experience failure at the same time due to shared physical dependencies such as power and networking sources.

Fault domains typically represent hierarchies that are related to these shared dependencies, with more servers likely to fail together from a higher point in the fault domain tree. During runtime, network controllers enumerate the fault domains in the cluster and attempt to spread out the network controller services so that they are in separate fault domains. This process helps ensure, in case of failure of any one fault domain, that the availability of that service and its state is not compromised.

Fault domains are specified in a hierarchical format. For example: /DC1/Rack1/Host1, where DC1 is the datacenter name, Rack1 is the rack name and Host1 is the name of the host where the node is placed.

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

-Force

Forces the command to run without asking for user confirmation.

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

-Name

Specifies the friendly name of the computer to be added to the deployment.

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

-NodeCertificate

Specifies the certificate used for authenticating the computer. You should only specify this parameter if the cluster is using certificate based authentication.

Type:	X509Certificate2
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

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

-RestInterface

Specifies the name of the interface on the node that will receive requests from Representational State Transfer (REST) clients.

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

-Server

Specifies the fully qualified domain name (FQDN), IP address, or hostname of the computer to be added to the deployment. If Kerberos is being used for cluster authentication, the FQDN must be provided.

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

-UseSsl

Indicates that the remote computer uses the Secure Sockets Layer (SSL) protocol to establish a connection to the Network Controller node. The default value of this parameter is false. Specify this parameter only if you run this cmdlet on a computer that is not part of the network controller cluster.

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.

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

Outputs

This cmdlet returns an object that contains the following fields:

• Name of the node
• Hostname, FQDN, or IP address of the node
• Fault domain of the node
• Name of interface to be used for REST operations on the node
• Node certificate
