Error Log Analysis

This chapter provides information on how to interpret error logs reported by the

operating system.

• Section 4.1 describes machine check/interrupts and how these errors are

detected and reported.

• Section 4.2 describes the entry format used by the error formatters.

• Section 4.3 describes how to generate a formatted error log using the

DECevent Translation and Reporting Utility available with OpenVMS and

Digital UNIX.

4.1 Fault Detection and Reporting

Table 4–1 provides a summary of the fault detection and correction components of

AlphaServer 1000A systems.

Generally, PALcode handles exceptions as follows:

• The PALcode determines the cause of the exception.

• If possible, it corrects the problem and passes control to the operating system

for reporting before returning the system to normal operation.

• If error/event logging is required, control is passed through the system control

block (SCB) to the appropriate exception handler.
