This section provides information about unconfiguring a CVM cluster using the GUI-based SFW Configuration Wizard for Microsoft Failover Cluster and the CLI-based ffconfigcli.exe utility. The section provides information about unconfiguring the entire cluster as well as about removing one or more nodes from the CVM cluster.
Please note the following important information before unconfiguring a CVM cluster using the wizard or utility:
While unconfiguring a CVM cluster, none of the CVM resources should be online on any of the cluster nodes. Similarly, while removing a node, no resources should be online on the node that you want to remove.
To run the wizard on a node, the CLUSSVC service must be running irrespective of the operation being carried out. However, if you are running the wizard on a node that is not going to be removed, then the CLUSSVC service can be stopped on the node being removed.
On the other hand, the CLI utility functions differently from the wizard. For adding a node and configuring a cluster, the utility requires that the CLUSSVC service is running. However, for removing a node and unconfiguring a cluster, it does not matter if the CLUSSVC service is running or stopped on any node.
Unconfiguring a CVM cluster does not delete any CVM link information that the wizard (or utility) automatically populates or the administrative user manually creates.
For information about configuring a CVM cluster,
Using the SFW Configuration Wizard for Microsoft Failover Cluster
