About the Topology
The software determines the topology by looking at the following:
• Fibre channel switch The fibre channel switch contains a list of all elements within the fabric.
The software obtains a detailed listing of all elements connected to the switch fabric.
• A host containing a Host Bus Adapter (HBA) All fibre channel host adapters look for
available elements attached to the HBA. This information is gathered by CIM Extensions and
sent to the management server.
