If Many-to-Many Connections Link HBAs and Ports
Figure 8 is an example of a network on which a production server and a development server are
connected to the storage system. (Henceforth, this network is referred to as network B). The HBA
(wwn01) in the production server is connected to four ports (1A, 1C, 2A and 2C). The HBAs (wwn02
and wwn03) in the development server are also connected to the four ports.
Figure 8 Network B (many-to-many connections are established between HBAs and ports)
.
If many-to-many connections are established between HBAs and ports, take the following major steps:
1. Find WWNs of HBAs. Before using XP Performance Control, you must find the WWN of each
HBA for each host server. WWNs are 16-digit hexadecimal numbers used to identify HBAs. For
details on how to find WWNs, see the HP StorageWorks XP24000/XP20000 LUN Manager
User Guide.
2. Ensure that all HBAs connected to ports in the storage system are monitored. Use the WWN tab
of the Performance Control window to define which port is connected to which HBA. Place icons
for HBAs connected to each port below the Monitor icons.
In network B, each of the four ports is connected to three HBAs (wwn01, wwn02, and wwn03).
Place the HBA icons of wwn01, wwn02, and wwn03 below the Monitor icons for all the four
port icons (shown in
Figure 9 ).
The resulting definitions on the window are as follows:
