HP StorageWorks 2.140 Director Switch - Manual (Page 74)

Managing the HAFM application 72
Discovering a SAN
The application discovers products, fabrics, and connections in a SAN. Through discovery, you can
manage and monitor your SAN in real time, ensuring that any issues are resolved immediately. This
section provides instructions for configuring the discovery feature.
Understanding how discovery works
Discovery is the process by which the application contacts the devices in the SAN. The application
illustrates each product and its connections on the Physical Map. After you log in and configure and
turn on discovery, the application discovers products connected to the SAN.
When performing out-of-band discovery, the application connects to the switches through the IP
network, and product information is copied from the SNS database on the switch to the appliance.
Only fabrics that have HP switches as the principal switch are displayed. If a HP switch is being
directly managed, but exists in a fabric where the principal switch is a third-party device, another
appliance is not allowed to connect to and manage that device.
NOTE: Ensure that your SNMP communication parameters are set correctly in order to discover
switches. Otherwise, the discovery can fail.
Configuring discovery
To define the devices you want discovery to find:
1. Select Discover > Setup.
The Discover Setup dialog box is displayed (
