Discovering a fabric and a host

Discovering a fabric and a host
You can discover, edit, and delete a fabric or a host in two ways:
• Using the SMIA extrinsic method
• Using the SMIA Configuration Tool
Fabric discovery using SMIA extrinsic method
The CIMOM fabric discovery process enables the user to discover and delete fabrics through an
extrinsic method implemented in the Brocade_DiscoveryService. It allows the user to edit the user
credentials and the Simple Network Management Protocol (SNMP) configurations so that a fabric
containing switches with different credentials and SNMP configurations can be managed
effectively.
Features supported
The following features are supported by the CIMOM fabric discovery:
• Option to discover all types of Storage Area Network (SAN) fabrics supported by the Brocade
Network Advisor.
• Option to edit the switch credentials and the SNMP configurations used to discover the fabric
after the fabric is discovered.
• Option to delete a fabric based on the fabric CIM Object Path (COP).
• If the discovery of one of the Virtual Fabric (VF) fails, the return parameter is set to
PARTIALLY_DISCOVERED and the out parameter contains the Fabric Identifier (FID) and the
error code of the fabric that failed to get discovered.
Limitations
The following are the limitations of the CIMOM fabric discovery:
• All the contexts are discovered by default in the VF. The user cannot select the contexts to be
discovered, but can delete the unwanted contexts through the DeleteFabric extrinsic method.
• Monitor and un-monitor operations are not supported.
• No provision to change the seed switch.
• No preset option available for discovering an Intrepid 10K.
Data model
• The Brocade_Fabric has two new additional properties, SeedSwitchWWN and SeedSwitchIP.
• The connection setting of each switch is associated to the discovery service.
• Every switch in the discovered fabric is represented with an instance of
Brocade_SwitchConnectionSettings. This instance gives the data to be provided in the discover
Fabric dialog box of the Brocade Network Advisor client, such as switch status, user ID, and so
on.
• The discovery service is hosted on the management server.
Figure 1 shows the data model of the fabric discovery through the SMIA extrinsic method.
