6-6 Server Priority Manager Operation

If Many-to-Many Connections Link HBAs and Ports
Figure 6-4 gives an example of a network in which a production server and a
development server are connected to the storage system (Henceforth, this
network is referred to as network B). The host bus adapter (wwn01) in the
production server is connected to four ports (1A, 1C, 2A and 2C). The host bus
adapters (wwn02 and wwn03) in the development server are also connected
to the four ports.

Figure 6-4 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 host bus adapters. Before using Server Priority Manager, you
must find the WWN (Worldwide Name) of each host bus adapter in host
servers. WWNs are 16-digit hexadecimal numbers used to identify host bus
adapters. For details on how to find WWNs, see the LUN Manager User's
Guide.
2. Ensure that all host bus adapters connected to ports in the storage system
are monitored. Use the WWN tab of the Server Priority Manager window
to define which port is connected to which host bus adapter. Place host bus
adapters connected to each port below the Monitor icons.
In network B, each of the four ports is connected to three host bus
adapters (wwn01, wwn02, and wwn03). Place the host bus adapter icons of
wwn01, wwn02, and wwn03 below the Monitor icons for all the four port
icons.
