CLUS_STARTING_PARAMS (clusapi.h) |
Indicates whether a node's attempt to start the Cluster service represents an attempt to form or join a cluster, and whether the node has attempted to start this version of the Cluster service before. |

Indicates whether a node's attempt to start the Cluster service represents an attempt to form or join a cluster, and whether the node has attempted to start this version of the Cluster service before. Resource DLLs receive the CLUS_STARTING_PARAMS structure with the CLUSCTL_RESOURCE_TYPE_STARTING_PHASE1 and CLUSCTL_RESOURCE_TYPE_STARTING_PHASE2 control codes.
Byte size of the structure.
Indicates whether this particular start of the Cluster service represents a form or a join operation.
The node starting the Cluster service is attempting to form a cluster. No other nodes are currently active.
The node starting the Cluster service is attempting to join an existing cluster. At least one other node is currently active.
Indicates whether this version of the Cluster service has ever started on the node.
The node is starting a version of the Cluster service for the first time.
The node has started this version of the Cluster service previously.
The CLUS_STARTING_PARAMS structure allows resource DLLs to respond to the CLUSCTL_RESOURCE_TYPE_STARTING_PHASE1 and CLUSCTL_RESOURCE_TYPE_STARTING_PHASE2 control codes based on the circumstances of the start. For example, a DLL might perform special initialization steps when the cluster forms, and perform another set of operations in response to joins.
The following example illustrates an abbreviated implementation of ResourceTypeControl. For more information, see Implementing ResourceTypeControl.
