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.
Table 13 Troubleshooting Discovery and Discovery Data Collection/Get Details
Scenario Description What to do
The host appears discovered
and it is connected to the

host, but it cannot obtain
additional information about it.

installed on the host.
Discovery from HP SIM
Discover the host again in HP
Systems Insight Manager. Then,
run Discovery Data Collection.
Discovery from HP SE
