HP Medical Archive Solution manual CBSB-Object Send Begin Fields

Message Reference

This audit message means a node-to-node data transfer operation was completed. If the Transfer Result was successful, the operation trans- ferred data from “Start Sequence Count” to “Actual End Sequence Count”. Sending and receiving nodes are identified by their node IDs. This information can be used to track system data flow and to locate, tabulate, and analyze errors. When combined with storage audit mes- sages, it can also be used to verify replica counts.

CBSB—Object Send Begin

During normal system operations, content blocks are continuously transferred between different nodes as data is accessed, replicated and retained. When transfer of a content block from one node to another is initiated, this message is issued by the source entity.

Table 12: CBSB—Object Send Begin Fields

Code	Field	Description
CNID	Connection	The unique identifier of the node-to-node content block
	Identifier	transfer.
CBID	Content Block	The unique identifier of the content block being
	Identifier	transferred.
CTDR	Transfer Direction	Indicates if the CBID transfer was push-initiated or pull-
		initiated:
		PUSH—the transfer operation was requested by the
		sending entity.
		PULL—the transfer operation was requested by the
		receiving entity.
CTSR	Source Entity	The node ID of the source (sender) of the CBID transfer.
CTDS	Destination Entity	The node ID of the destination (receiver) of the CBID
		transfer.
CTSS	Start Sequence	Indicates the first sequence count requested. If success-
	Count	ful, the transfer begins from this sequence count.
CTES	Expected End	Indicates the last sequence count requested. If successful,
	Sequence Count	the transfer is considered complete when this sequence
		count has been received.
RSLT	Transfer Start	Status at the time the transfer was started:
