SymptomsYou are able to successfully add NetApp storage to System Center 2012 Virtual Machine Manager (VMM) and create the LUN’s but when trying to assign the available storage to a Hyper-V cluster, the job fails with the error below:
Error (20400)
1 parallel subtasks failed during execution.
Error (26184)
The Storage Group existing for <Cluster Name> doesn’t match storage group setting at array <Storage>.
Recommended Action - Make sure storage group setting set at storage array matches storage groups created for cluster.

This can occur if there is more than one Storage initiator group assigned per Cluster node.
ResolutionTo resolve this issue follow the steps below:
1. Reduce the Storage initiator groups to one per cluster node in NetApp storage.
2. To get the changes reflected in the VMM server, we need to Remove and re-add the storage device in the VMM console.
3. In the VMM console, from the
Fabric
pane, remove the storage device.
4. Verify the Storage removal job completed successfully.
5. On the Home tab, in the Add group, click Add Resources and then click Storage Devices. The Add Storage Devices Wizard starts.
6. Provided the required details and add the storage device.
Now you need to configure the storage classification and storage pools again. After that you should be able to assign the available to storage to a Hyper-V cluster in the VMM console.
