About the ServerNet II Switch Firmware and Configuration
To understand the role of firmware and configuration in a ServerNet cluster, you must
understand the ServerNet II Switch subcomponent of the cluster switch. The ServerNet
II Switch contains:
•
Router-2 ASIC
•
Microprocessor
•
Flash memory
•
Random access memory (RAM)
Firmware is software that processes and replies to in-band control (IBC) manageability
commands sent by the external ServerNet SAN manager process (SANMAN). The
firmware configures the router-2 ASIC according to the configuration.
The configuration defines the ServerNet node numbers assigned by the cluster switch
and the router-2 ASIC routing table. The configuration determines the position of the
switch in the topology and the ServerNet node numbers that the switch supports.
Table 4-30 shows the cluster switch positions and ServerNet node numbers.
Caution. HP recommends that you have a spare cluster switch on site or have ready access
to a spare cluster switch before starting any upgrade procedure that includes a firmware or
configuration change.
