Question

_{Wednesday, September 5, 2012 12:29 AM}

I am looking for a method to detect the status of a cluster resource from command line. This will be used as part of a script on all cluster nodes to determine where a specific group / resource is online before issuing further resource related commands. Unfortunately I do not have access to a cluster to try some commands. Can someone please give me the outputs for following commands or recomend a better command? I prefer to use the command line.

cluster group <group name> /status

cluster resource <resource name> /status

cluster node /status

Thanks

Hello Rama,

I suggest you can use cluster res command to know the status of all resources with corresponding groups & nodes. Moreover it is a single command to monitor cluster resources status.

BTW find the below info and your commands output will be like.

- C:\cluster group "Clust Group" /stat
  Listing status for resource group 'Group':
  Group Node Status
  
  Clust Group ABC Online
- C:\cluster res "resource-name" /stat
  Listing status for resource 'resource-name':
  Resource Group Node Status
  
  resource-name clust group ABC Online
- C:\cluster node "ABC" /stat
  Listing status for node 'node-name':
  Node Node ID Status
  
  ABC 2 Up

It will work as long as the cluster service is running on this node.

C:\Documents and Settings\Administrator.WIN2K3CLUSTER>cluster resource /status

Listing status for all available resources:

Resource Group Node Status

Disk Q: Cluster Group WIN2K3R2-1-SW Online

Cluster IP Address Cluster Group WIN2K3R2-1-SW Online

Cluster Name Cluster Group WIN2K3R2-1-SW Online

Disk Q: (lost) Cluster Group WIN2K3R2-1-SW Online

Private 2 Cluster Group WIN2K3R2-1-SW Online

C:\Documents and Settings\Administrator.WIN2K3CLUSTER>cluster node /status

Listing status for all available nodes:

Node Node ID Status

WIN2K3R2-1-SW 2 Up

WIN2K3R2-2-SW 1 Up

C:\Documents and Settings\Administrator.WIN2K3CLUSTER>cluster group /status

Listing status for all available resource groups:

Group Node Status

Cluster Group test WIN2K3R2-1-SW Online

Cluster Group WIN2K3R2-1-SW Online

If this is something you plan on using for a while, I would suggest that you look at PowerShell instead of cluster.exe. Cluster.exe is deprecated in 2012. PowerShell is available for both 2008 and 2012.

Here is the output from the PowerShell Get-ClusterResource showing both online and offline resources.

Thanks for your reply. But those links do not show the command output / format.

_{Wednesday, September 5, 2012 3:38 AM}

Ramassh, consider using power shell.

Thanks Ravi. Do these commands work on passive nodes too? I would like to see the result on a more than 2 node cluster too with 'Offline' nodes. Can you please help?

Yes you can run from passive node but you can't run it from offline node.

_{Wednesday, September 5, 2012 8:56 AM}

Thanks Leon. I believe this is a 2 node cluster.

I don't see the offline details reported in these outputs. So anything not reported here are considered 'Offline'? For example, if you run the follwoing command on both online and offline nodes will they show whether the group is offline on the passive node?

cluster group "Cluster Group" /status

_{Wednesday, September 5, 2012 1:13 PM}

Hi Ramassh,

It will show as "Offline" if the group or resource is currently in offline status.

Both nodes will show the same result becasue they are in one cluster.

Thanks,
Leon

Hi Leon, Ravi

Thanks for your replies, much appreciated. I am still not convinced that command reports offline groups. Do you have online/offline state group in a 2 node cluster? If so can you please run the following command on both nodes and paste the results?

cluster group <online/offline group name> /status

For me it looks like the offline group nodes are never reported. Only the online ones are reported, even from the offline group node.

Thanks :)

Thanks Tim. Is there a replacement for cluster.exe in 2012? I need to use a command line as I may not have access to the file system to store a script. Is this info available in WMI?

_{Thursday, September 6, 2012 2:18 PM}

PowerShell is the replacement, and it is a command line. And, PowerShell V3 is remotable, so you can execute commands from a management system against a remote, managed system, such as a cluster. That's the way I tend to do it a lot of the time.

My guess is that you can also find the information in WMI, but I am not a programmer, and trying to find what I need in WMI takes too long for me. Since PowerShell exposes everything you need, it is much faster. (Often, what a PowerShell cmdlet does is read the WMI information.)

Hi All,

I am trying to use WMI query check the status of the nodes in a cluster group. Can you please give me the output of the following powershell commands? Please replace the groupname to suit a online/offline group in your system:

$Query = "select * from MSCluster_NodeToActiveGroup where PartComponent=`"MSCluster_ResourceGroup.Name='GroupName'`""
Get-WmiObject -namespace root\mscluster -query $Query

If that fails, please try:

$Query = "select * from MSCluster_NodeToActiveGroup"
Get-WmiObject -namespace root\mscluster -query $Query

I will be using a VB script to run this query. I need to know the output fields to read the node status. Please correct or suggest better commands!

Thanks

Hello Rama,

I suggest you set-up a test lab for practice.This forum is dedicated for the issues occur in real time environment.

Alternatively use Technet virtual labs.
