The following terms are specific to this document:

characteristic: A read-only, intrinsic attribute associated with a cluster object.

cluster network: A distinct communication path between a set of nodes that typically represents a subnet in the underlying network infrastructure.

cluster network interface: An instance of a connection point on a cluster network that is associated with a specific node.

cluster object: An entity that can be accessed or managed via the ClusAPI Protocol. A cluster object is either a cluster, node, resource, group, cluster network, cluster network interface, or cluster registry key.

cluster registry: A hierarchical data store that has lightly typed elements and that is stored by and accessed through the cluster. The abstraction that is presented to clients is similar to that presented by the Windows registry.

cluster registry root key: The root key of the cluster registry. The root key is described in [MS-RRP] section 3.1.1.1.1.

cluster security descriptor: A security descriptor that is associated with the management of a cluster.

common property: A named element of a schema defined by the server and specific to a cluster object. A schema element has at least one value consisting of a type and a format. Each object instance maintains its own set of values, which is part of the object's nonvolatile configuration data. All cluster objects, with the exception of a cluster registry key, have common properties.

disk number: An integer value that can be used to identify a device in the system device namespace.<1>

group: A cluster group is a container for zero or more clusterresources, when referring to cluster groups. Groups enable resources to be combined into larger logical units and are owned by only one node in the cluster at a time.

network: A communications infrastructure over which two or more nodes in the cluster can communicate with one another. A cluster network represents a subnet on which a network interface is connected.

network interface: An interface on a cluster network that is connected to a node and is used to communicate with other nodes on the same network.

notification port: An event creation mechanism, subscribed to by applications, that provides information about changes in the state and configuration of one or more objects in the cluster state.

private property: A named element of a schema defined by and specific to a cluster object. A schema element has at least one value consisting of a type and a format. Not all objects define private schemas and an object can define the private schema for another object. If a schema is defined, each object instance maintains its own set of values, which are part of the object's nonvolatile configuration data.

protocol server state: A status that is local to a server and that indicates the server's ability to accept ClusAPI Protocol requests that operate on the cluster state.

resource: Any physical or logical component that can be managed by a cluster. A resource is owned by a single node at any one time.

resource class: A collection of resources that share a similar trait.

resource dependency: A relationship between two resources in which one resource cannot be online unless the other is online.

resource persistent state: A resource state to which the resource was most recently commanded to transition by a client.

resource private property: The part of a resource's nonvolatile configuration data whose schema is specific to the resource type.

resource type: A clusterresource type that uniquely categorizes clusterresources and codifies the functionality that is required for a node to own that resource in a cluster.

resource type private property: The part of a resource type's nonvolatile configuration data whose schema is specific to the resource type. The private properties of a resource type and its resources can be identical, can intersect, or can be mutually exclusive.

storage pool: A group of disks where all of the storage space on all of the disks is aggregated and managed as a single unit.

storage pool drive: A disk that is part of a storage pool.

top-level resource: A resource that no resource depends on.

MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as specified in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
