New-Cluster

  • Reference
Module:
FailoverClusters

Creates a new failover cluster.

Syntax

New-Cluster
   [-Name] <String>
   [-Node <StringCollection>]
   [-StaticAddress <StringCollection>]
   [-IgnoreNetwork <StringCollection>]
   [-NoStorage]
   [-S2D]
   [-ManagementPointNetworkType <AdminAccessPointResType>]
   [-AdministrativeAccessPoint <AdminAccessPoint>]
   [-Force]
   [<CommonParameters>]

Description

The New-Cluster cmdlet creates a new failover cluster. Before creating a cluster, the hardware (servers, networks, and storage) must be connected, and the validation tests must be run.

Use Test-Cluster to run the validation tests. The tests will confirm that the hardware and settings are compatible with failover clustering. There are multiple types of tests, including Inventory, System Configuration, Network, Storage, and other types of tests.

Tip

You should run the New-Cluster command from a cluster node or client that is the same version as the cluster nodes. Running New-Cluster from a lower-level (down-level) client computer may require Update-ClusterFunctionalLevel to be run after New-Cluster has been run.

Examples

Example 1

New-Cluster -Name cluster1 -Node node1,node2,node3,node4

This example creates a four-node cluster named cluster1, using default settings for IP addressing.

Example 2

New-Cluster -Name cluster1 -Node node1,node2 -NoStorage

This example creates a two-node cluster named cluster1. The cluster will not have any clustered storage, or disk resources. Storage can be added using the Get-ClusterAvailableDisk cmdlet with the Add-ClusterDisk cmdlet.

Example 3

New-Cluster -Name cluster1 -Node node1,node2,node3,node4 -StaticAddress 2.0.0.123

This example creates a four-node cluster named cluster1 that uses the static IP address 2.0.0.123.

Example 4

New-Cluster -Name cluster1 -Node node1,node2,node3,node4 -StaticAddress 2.0.0.123,3.0.0.123

This example creates a four-node cluster named cluster1 that uses the static IP addresses 2.0.0.123 and 3.0.0.123.

Example 5

New-Cluster -Name cluster1 -Node node1,node2,node3,node4 -IgnoreNetwork 2.0.0.0/8

This example creates a four-node cluster named cluster1. The cluster uses default settings for IP addressing, and doesn't use the network 2.0.0.0/8.

Example 6

$parameters = @{
    Name = 'cluster1'
    Node = 'node1','node2','node3','node4'
    StaticAddress = '2.0.0.123'
    IgnoreNetwork = '3.0.0.0/8'
}
New-Cluster @parameters

This example creates a four-node cluster named cluster1. The cluster uses the static IP address 2.0.0.123, and doesn't use the network 3.0.0.0/8.

This example uses splatting to pass parameter values from the $Parameters variable to the command. Learn more about Splatting.

Parameters

-AdministrativeAccessPoint

Specifies the type of administrative access point that the cmdlet creates for the cluster. The acceptable values for this parameter are:

  • ActiveDirectoryAndDns. The cmdlet creates an administrative access point for the cluster. The administrative access point is registered in DNS and enabled in Active Directory Domain Services.

  • Dns. The cmdlet creates an administrative access point for the cluster. The administrative access point is registered in DNS but isn't enabled in Active Directory Domain Services.

  • None.

The cmdlet doesn't create an administrative access point for the cluster. Some clustered roles and functionality might not be available for a cluster that doesn't have an administrative access point. Also, you cannot use Failover Cluster Manager to manage a cluster that doesn't have an administrative access point.

Type:AdminAccessPoint
Aliases:aap
Accepted values:None, ActiveDirectoryAndDns, Dns, ActiveDirectory
Position:Named
Default value:None
Required:False
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

-IgnoreNetwork

Specifies one or more networks to ignore when running the cmdlet. Networks with DHCP enabled are always included, but other networks need a static address to be specified using the StaticAddress parameter or should be explicitly ignored with this IgnoreNetwork parameter.

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

-ManagementPointNetworkType

Specifies the network configuration used to determine IP address settings.

The acceptable values for this parameter are:

  • Automatic: Automatically detects the appropriate setting. If SQL Server is running in Azure, uses Distributed. If SQL Server is running on-premises, uses Singleton. (Default setting)
  • Singleton: The traditional method of DHCP or static IP address.
  • Distributed: Uses a Distributed Network Name by using Node IP addresses.
Type:AdminAccessPointResType
Position:Named
Default value:Automatic
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Name

Specifies the name of the cluster to create.

Type:String
Position:0
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-Node

Specifies a comma-separated list of cluster node names, or server names, on which to create the cluster. If this parameter isn't specified, then a one node cluster is created on the local physical computer.

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

-NoStorage

Specifies that shared storage is ignored during the cluster creation. The cluster created at the end of the operation will not have shared storage. Shared storage can later be added by piping the ClusterDiskInfo object from the Get-ClusterAvailableDisk cmdlet into the Add-ClusterDisk cmdlet.

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

-S2D

Specifies whether to enable Storage Spaces Direct when creating the cluster.

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

-StaticAddress

Specifies one or more static addresses to use when running the cmdlet. Networks with DHCP enabled are always included, but other networks need a static address to be specified using the StaticAddress parameter or should be explicitly ignored with this IgnoreNetwork parameter.

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

Inputs

None

Outputs

Microsoft.FailoverClusters.PowerShell.Cluster

Notes

  • This cmdlet cannot be run remotely without Credential Security Service Provider (CredSSP) authentication on the server computer.
