Cluster Configuration Using the BUI

To configure or unconfigure a cluster, use the following procedures.

Unconfiguring clustering is a destructive operation that returns one of the clustered storage controllers to its factory default configuration and reassigns ownership of all resources to the surviving peer. There are two reasons to unconfiguring clustering. You no longer wish to use clustering; instead, you wish to configure two independent storage appliances. You are replacing a failed storage controller with new hardware or a storage controller with factory-fresh appliance software (typically this replacement is performed by your service provider).
