When a checkstop or machine check occurs, it is indicated by an LCD of 45800001. Firmware routines are automatically invoked, which result in one of two AIX error log entries:
Error data is encoded with these logs in accordance with RPA. Run the Error Log Analysis (ELA) to get AIX to process the error log data.
During boot, a processor may fail diagnostic tests and be deleted from the system. This could cause a decrease in the node's performance. When this occurs, an AIX error log entry is written.
