Get-ClusterGroup

  • Reference
Module:
FailoverClusters

Gets information about one or more clustered roles (resource groups) in a failover cluster.

Syntax

Get-ClusterGroup
   [[-Name] <StringCollection>]
   [-VMId <Guid>]
   [-InputObject <PSObject>]
   [-Cluster <String>]
   [<CommonParameters>]

Description

The Get-ClusterGroup cmdlet gets information about one or more clustered roles (resource groups) in a failover cluster.

A resource group is the unit of failover. During failover, all resources in the resource group move together.

Examples

Example 1

PS C:\> Get-ClusterGroup
Name                       OwnerNode                                      State 
----                       ---------                                      ----- 
Available Storage          node1                                         Online 
Cluster Group              node2                                         Online 
cluster1FS                 node1                                         Online 
cluster1FS-Other           node1                                         Online

This example lists the state and owner node of each clustered role, or resource group, in the local cluster.

Example 2

PS C:\> Get-ClusterGroup -Name "Cluster Group" | Get-ClusterResource
Name                State               Group               ResourceType 
----                -----               -----               ------------ 
Cluster Disk 1      Online              Cluster Group       Physical Disk 
Cluster IP Address  Online              Cluster Group       IP Address 
Cluster IP Addre... Online              Cluster Group       IPv6 Address 
Cluster Name        Online              Cluster Group       Network Name

This example lists the resources in Cluster Group on the local cluster.

Example 3

PS C:\> Get-ClusterNode -Name node1 | Get-ClusterGroup
Name                       OwnerNode                                      State 
----                       ---------                                      ----- 
Cluster Group              node1                                         Online

This example lists the clustered services and applications, or resource groups, that are currently owned by node1 in the local cluster.

Example 4

PS C:\> Get-ClusterGroup -Name FileServer1 | Format-List -Property *
Cluster                :  Cluster1 
IsCoreGroup            : False 
OwnerNode              :  node1 
State                  : Online 
Name                   :  FileServer1 
Description            : 
PersistentState        : 0 
FailoverThreshold      : 4294967295 
FailoverPeriod         : 6 
AutoFailbackType       : 0 
FailbackWindowStart    : 4294967295 
FailbackWindowEnd      : 4294967295 
AntiAffinityClassNames : {} 
Id                     :  189ec8ad-1831-4f57-9bb0-3ffb9cbb9227

This example displays the properties of a clustered file server, or resource group, called FileServer1, in the form of a list.
