A system, method and computer program product for intelligent discovery of network information from multiple information gathering agents adapted to discover information concerning the network. The discovery agents each have an associated discovery capability. Based on consideration of the agent discovery capabilities, discovery assignments are computed and network discovery is performed according to the assignments so as to reduce discovery poll overhead.

Techniques for identifying and selecting equivalent sets of agents with defined capabilities to perform certain actions are disclosed herein. In one embodiment, determining agents to gather information for a storage area network fabric may be performed through the use of fabric discovery operations which identify agents capable of performing various actions within the fabric. From the determined capabilities of the agents, a dynamic capability grid may be populated to assist with the generation of a list of equivalent subsets to perform the various actions. The most efficient set of agents from each equivalent subset may then be selected to perform actions, with other sets of agents in the equivalent subset available as secondary choices in case of an unexpected failure. For example, a fabric probe may be executed in a storage area network using discovered agents from a list of equivalent subsets to most efficiently accomplish network operations such as zoning and topology.

Novel storage area networks (SANs) and methods of operation thereof utilize a plurality of hosts coupled via an interconnect with one or more storage units. A manager device, process or other functionality in communication with a plurality of agent processes, devices or other functionality, each of which is associated with a host. The agents identify attributes of (i) their associated hosts, (ii) interconnect to which that host is coupled, and/or (iii) storage units to which that host is coupled via the interconnect. The manager responds to these attributes identified by the agents to manage the SAN. The manager can be implemented on a first digital data processor and the hosts on further digital data processors. These digital data processors can be coupled via a first network, e.g., an IP or other network, to support communications between the manager and the agents. A second network, e.g., SCSI and/or fiber channel based fabric, separate from the first network, can be utilized as the interconnect between the hosts and the storage devices.

The present disclosure provides techniques for updating fabric alert definitions defined for a fiber channel or other fabric-based network within a storage management system. One embodiment provides techniques for detecting fabric merges, fabric segmentations, and principal switch changes of the fabric and modifying fabric alert definitions as a result of these changes. Thus, any alert definitions scoped by fabric will remain relevant even after fabric structural changes, and duplicate and/or redundant alerts may be reduced within the storage management system. In a further embodiment, detection of fabric changes is performed by first storing relationships between fabrics and switches, and comparing the current relationships between the fabrics and the switches against the stored relationships. Upon recognition of changes within the fabrics, the fabric alert definitions may be automatically analyzed and updated.
摘要:
A detectibility service for a storage infrastructure manager (SIM) operating on a storage area network (SAN) is disclosed directed to addressing a situation where there may be multiple sources of duplicate or contradictory information to the SIM about the presence and condition of an element in the SAN. The service can account for both authoritative as well as nonauthoritative sources of information in a SAN, which participate in the discovery process scanning for SAN elements. Both authoritative and nonauthoritative sources of information can be used to report a given SAN element during a probe, taking advantage of the more efficient processing of information from authoritative sources to override information from nonauthoritative sources regardless of the order in which the various scans may occur.
