.NAME
Cluster .DESCRIPTION Used to configure a failover cluster. If the cluster does not exist, it will be created in the domain and the static IP address will be assigned to the cluster. When the cluster exist (either it was created or already existed), it will add the target node ($env:COMPUTERNAME) to the cluster. ## Requirements * Target machine must be running Windows Server 2008 R2 or later. .PARAMETER Name Key - String Name of the Cluster .PARAMETER StaticIPAddress Write - String StaticIPAddress of the Cluster .PARAMETER DomainAdministratorCredential Write - Instance Credential to create the cluster .PARAMETER IgnoreNetwork Write - StringArray One or more networks to ignore when creating the cluster. Only networks using Static IP can be ignored, networks that are assigned an IP address through DHCP cannot be ignored, and are added for cluster communication. To remove networks assigned an IP address through DHCP use the resource ClusterNetwork to change the role of the network. This parameter is only used during the creation of the cluster and is not monitored after. .PARAMETER KeepDownedNodesInCluster Write - Boolean Remove nodes in down state from cluster. .EXAMPLE 1 This example shows how to create the failover cluster on the first node.

NOTE! Please remove comment from this row to be able to use your certificate.

THIS IS NOT RECOMMENDED IN PRODUCTION. This is added so that AppVeyor automatic tests can pass, otherwise the tests will fail on passwords being in plain text and not being encrypted.

Please note that if the CNO is prestaged, then the computer object must be disabled for the resource Cluster to be able to create the cluster.
