On Windows Server 2012, the Microsoft Failover Cluster Manager UI tool has a defect. When a “right-click” is performed on a DataKeeper Volume resource from the Available Storage group, the drop-down action list does not appear. That action list would normally include the “Delete” command (among other actions) to delete the resource from the cluster.

Unfortunately, when the Admin is finished using a DataKeeper Volume storage resource, the resource cannot be removed from the cluster with the Failover Cluster Manager UI tool. This appears to affect only non-Microsoft storage resources. Microsoft is working on a correction for this.

Suggested Action

Microsoft has released a Server 2012 Hotfix for this defect. Microsoft Article 2804526 provides a high level overview of several WSFC Server 2012 issues including this problem. This article will refer you to several hotfixes for Server 2012. Installing Microsoft Hotfix 2795997 will correct this particular problem. Windows Update KB2803748 must also be installed (this normally occurs automatically). If KB2803748 is not installed, the cluster will become unstable

When requesting this hotfix, click on “Show hotfixes for all platforms and languages” and check the x64 selection. Be sure to also update your 2012 Server with all Windows Updates after installing this hotfix.

The workaround for this issue without installing the Microsoft hotfix is to delete the “DataKeeper Volume” resource using Windows PowerShell. To remove a DataKeeper Volume resource from a cluster with PowerShell, perform the following command:

remove-clusterResource “<DataKeeper Resource Name>”

For example:

In the above example, replace “New DataKeeper Volume” with the actual name of your DataKeeper Volume resource.
