Errors and Reading Error Logs
The information provided by error logs is useful for troubleshooting HP Integrity rx3600 server
faults and failures.
Event Log Definitions
The cause of an MCA event can be captured by system or BMC firmware in both the System Event
Log (SEL) and Forward Progress Log ( FP). Match these errors with MCA events using their
timestamps. For example, the loss of a CPU VRM causes a CPU fault. The MCA log does not
provide definitive diagnosis of the problem. Following are features and limitations of events and
event logs:
• Event logs are the equivalent of chassis logs for status or error information output.
• Symbolic names are used in the source code; for example, MC_CACHE_CHECK
• The hex code for each event log is 128 bits long with an architected format:
Some enumerated fields can be mapped to defined text strings.◦
◦ All fields can be displayed in hex, keyword, or text mode.
• Events are created by firmware or OS code and are sent over the PDH bus to the BMC for
storage in either or both of the SEL and FP logs.
• The iLO 2 MP can display event logs. SEL events are sent from the BMC to the iLO 2 MP over
the IPMB.
• Event logs can also be read back over the PDH bus by software for storage on disk.
Using Event Logs
To access the event logs, follow these steps:
1. Connect to the system console.
2. Enter Control-B to access the MP Main Menu.
3. Enter the sl command to view event logs.
