6.7.4.6 Error Logging and Event Log Entry Format

The Tru64 UNIX and OpenVMS error handlers generate several entry types. Error entries,
except for correctable memory errors, are logged immediately. Entries can be of variable length
based on the number of registers within the entry. Each entry consists of an operating system
header, several device frames, and an end frame. Most entries have a PAL-generated logout
frame, and may contain frames for CPU, memory, and I/O.
Figure 6-2 shows an error log event structure map for a Tru64 UNIX or OpenVMS system
uncorrectable PCI target abort error.
