Shutting Down a Clustered Configuration (CLI)
a transport for inter-controller communication within the cluster and are responsible for
monitoring the peer's state. This transport is used by the resource manager, which allows data
service providers and other management subsystems to interface with the clustering system.
Finally, the cluster management user interfaces provide the setup task, resource allocation and
assignment, monitoring, and takeover and failback operations. Each of these building blocks is
described in detail in the following sections.

Unconfiguring Clustering
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).
Because of the possibility of data loss to unconfigure clustering, contact Oracle support.
