Error Analysis with RMC
6.7.1 RMC and Error Information
The remote management console (RMC) manages an extensive network of FRU I

EEPROMs. Information from these EEPROMs is stored in dual-port RAM (DPR) and can be
accessed to diagnose hardware failures.
At system power-up, the RMC reads 256 bytes of data from each FRU EEPROM and stores it
in the dual-port RAM, a shared RAM that facilitates interaction between the RMC and the
system. The EEPROM data contains information on configuration and errors. The data is
accessible through the TIG chip on the system motherboard.
As one of its functions, the TIG provides interfaces for the firmware and the operating system
to communicate with the server management logic. The data accessed from DPR provides
configuration information to the firmware during start-up. Remote or local applications can
read the error log and configuration information. The error log information is written to the
dual-port RAM by an error handling agent and then written back to the EEPROMs by the
RMC. This arrangement ensures that the error log is available on a FRU after power has been
lost.
The RMC provides several commands for accessing error information in the shared RAM.
Compaq Analyze, described in Section 6.7.2, can also access the FRU EEPROM error logs to
diagnose hardware failures.
