How to Failover the ‘Cluster Group’ and ‘Available Storage” Cluster Groups
One question I get asked a lot working with our customers is how to failover the ‘Cluster Group’ and ‘Available Storage’ groups?
Under the covers, those two groups are still just groups like any other you’d see under ‘Services and Applications’ in Failover Cluster Manager. We just didn’t expose through the GUI, a way to fail those groups between nodes when you want to move say ‘Available Storage’ to a node you are working on so you can copy data to a cluster shared disk.
The resources in the ‘Cluster Group’ are located in the middle pane in Failover Cluster Manager when you highlight the name of the cluster underneath ‘Failover Cluster Manager’ in the left-hand pane.
Note in the above screenshot, in the top ‘Summary of Cluster’ box, the ‘Current Host Server: shows as JH-W2K8-R2SP1-2. That’s the node that currently owns the ‘Cluster Group’ or ‘Core Cluster Resources.
The below screenshot shows the ‘Available Storage’ group. This is a group containing cluster shared disks that have not yet been added to a ‘Services and applications’ group.
Note also that the current owner of the ‘Available Storage’ group shows as JH-W2K8-R2SP1-2.
So, there are two ways we can move either the ‘Cluster Group’ or the ‘Available Storage’ groups between nodes of the cluster.
The first way is with the cluster PowerShell cmdlet Move-ClusterGroup
Move-ClusterGroup “Cluster Group”
or
Move-ClusterGroup “Available Storage”
The second way is a cluster.exe command line
cluster group “Cluster Group” /move
or
cluster group “Available Storage” /move
If you have more than two nodes in the cluster, you can specify the destination node with the following syntax:
PowerShell:
move-ClusterGroup –node NodeName
where NodeName is where you want to move the group.
Command Line:
cluster group “Cluster Group” /Move:NodeName
where NodeName is where you want to move the group.

No, you do not have to run Cluster Validation if you move the Cluster Group to another node - Anonymous

The same approach applies to Cluster Shared Volumes (CSVs). Each of them is essentially a hidden cluster group as well.Currently, neither the group nor resource names for CSVs are exposed in PowerShell when listing. Cluster.exe doesn't show the group as well. So the only way to learn the group name is to list the resources. You filter the list by the friendly name of the CSV or a part of it (as seen in Failover Cluster Manager).PS C:Windowssystem32> .cluster.exe /cluster:"MyCluster.contoso.com" resource | findstr /i Disk-01Cluster Disk 1 - Disk-01 53f2937f-feb2-4dd4-ac20-7e2531023455 Node02 OnlineThe GUID is actually the Group name. (And it is not the same as internal object GUID). Knowing this name you can now use it either with Cluster.exe or with PowerShell.Get-Cluster -Name "MyCluster.contoso.com" | Get-ClusterGroup -Name "53f2937f-feb2-4dd4-ac20-7e2531023455" | Move-ClusterGroup - Anonymous

In 2012 and above, it was added to the GUI so you cam do failovers of these two groups more easily. - Anonymous

You cannot copy and paste the command and expect it to work. Oddly enough, I deleted both of the " and typed it out manually and the command worked. Guess copy and paste is not always the best. :)- Anonymous

why does paste not work, it's all text so why does this not work unless you type this out?

I'm curious. I see Available Storage when I list the cluster groups via powershell (get-clustergroup) but when I look at Failover Cluster Manger there is no group listed in the Storage Summary. Also, the Storage Summary header lists Available Capacity as: Total: 0 Bytes, Free Space: 0 Bytes, Percent Free: 0%Why is there an Available Storage group if there is no available capacity?Thanks - Anonymous

Is ther any different in using the GUI and Powershell and the Cluster.exe command ? - Anonymous

This article helped me solve a problem bringing online some disks that were not yet a part of a group in the cluster. I'm setting up a "geo-cluster" and these disks would try to come online on the node they haven't been added to yet. I thought it was a problem with the disks themselves, rather than an ownership issue with the "Available Storage" group. It all makes sense now....thanks! - Anonymous

Hi, do you need to run cluster validation after moving the cluster group?
Thanks for the info presented here,

WHY didn't you put it in the GUI? It was there in all previous versions of the OS that supported clustering. This sort of stuff is just frustrating... - Anonymous

Hello Jeff,
Kindly share the step by step document for Cluster setup. I want to setup the SQL Cluster.

Hi All, Greetings for the day!
I have an issue- There is a need to use clustered nodes for my application because of volume. A 3rd party vendor did clustering for us. First they had some issues using Quorum for sharing application resources. So, they have created a clustered disk which uses our App resources. So now we have one Active and one Passive node for our application.
Now, whenever user is running his session, it remains active and does not get disturbed on switching nodes from Active to Passive. But, it becomes inactive and of no use when switching from Passive to Active.
We ran the Failover Cluster Validation. In the wizard 'Review Storage Status' , I selected the clustered disk and not the Quorum volume. Here are the category results:
Cluster Configuration - Success
Inventory - Success
Network - Warning
Storage - Warning
System Configuration - Failed
Now, here are the results for 'System Configuration' :
Validate Active Directory Configuration - Failed
Validate All Drivers Signed - Success
Validate Cluster Service and Driver Settings - Success
Validate Memory Dump Settings - Success
Validate Operating System Edition - Success
Validate Operating System Installation Option - Success
Validate Operating System Version - Success
Validate Required Services - Success
Validate Same Processor Architecture - Success
Validate Service Pack Levels - Success
Validate Software Update Levels - Success
Validate System Drive Variable - Success
The Overall Result is:
Overall Result
Testing has completed, but one or more tests indicate that the configuration is not suitable for clustering.
Details for Failed section 'Validate Active Directory Configuration' is as below:
The distinguished name of node A could not be determined because of this error: There was an error getting information about the organization unit for node 'A' from the domain 'company.com'.
The organizational unit of node A could not be determined because of this error: Did not find an Organization Unit (OU) in the Active Directory
The distinguished name of node JDAPRDWMPS.sophiemartin.com could not be determined because of this error: There was an error getting information about the organization unit for node 'JDAPRDWMPS.sophiemartin.com' from the domain 'company.com'.
The organizational unit of node A could not be determined because of this error: Did not find an Organization Unit (OU) in the Active Directory
Connectivity to a writable domain controller from node A could not be determined because of this error: Could not get domain controller name from machine.
Node(s) JDAPRDWMAC.sophiemartin.com can reach a writable domain controller.
Node(s) JDAPRDWMPS.sophiemartin.com cannot reach a writable domain controller. Please check connectivity of these nodes to the domain controllers. - Anonymous

The Available Storage group will always be there whether there are any disks in it or not. When you first add a disk to Failover Cluster, it goes into the Available Storage group. From there, you can then add it to an Application Group such as SQL or a File Server.

Thanks. What I'm trying to do is create scripts to move ALL resources to 1 node so that node can be patched, then after patching run the same script on the other node to move all resources to the 1st node that was patched. Then I'll need another script to manually rebalance the cluster since it's active-active.
