Reading the Message and Code Display

Three types of messages (informational/run time, error, and warning) may occur during the reset, startup, or shutdown process.

Informational messages indicate which component the self-test is testing at any given time.
Error messages indicate a hardware failure or operating system error. Class errors are grouped into 14 classes ( 1-CE). They are hexidecimal messages that appear on the front panel LED display and access port status line. All other errors are considered non-class, and can appear on the panel or on the system console itself.
If a class error is encountered (see Table 8-1 “Class Error Descriptions” for the types of classes), the self-test halts and error messages are displayed.
Warning messages identify noncritical failures that do not prevent the system from booting or halt the self-test.

Information messages, error codes, and warnings are displayed (in hexadecimal) on the front panel LEDs, the access port status line during bootup, and the system console. English language messages can also appear in addition to or in place of a hexadecimal message at the console.




	NOTE: Some console messages are also logged to the system log file.

Interpreting Class Errors

Fifteen classes of codes comprise the informational, error, and warning messages. The class number is the leftmost hexadecimal value for the singular display and for the second multiplexed (alternating) display. Table 8-1 “Class Error Descriptions” lists the class error number, its hexadecimal code, and the cause of the error. To determine an error's class, check its numeric code in the table. Then locate the subsection in this chapter which addresses that class.

Table 8-1 Class Error Descriptions

Err.	Code	Description
1	11xx	Faulty register file.
1	14xx	Execution unit failure.
1	15xx	Instruction unit failure.
2	26xx	Translation look-aside buffer (TLB) failure.
2	27xx	Cache failure.
3	30xx	Faulty system monitor card.
4	42xx	Faulty assist processor.
5	5sxx	Bus protocol error.
6		Reserved.
7	7sxx	Faulty memory.
8	8sxx	Faulty I/O card.
9	01xx and 9xxx	Console test error.
A	01xx and Axxx	Boot device error.
B	Bxxx	Operating system software error.
C		Initialization messages.
CA	CAxx	Power fail.
CB	CBxx	Transfer of control.
CE	CExx	ISL messages and error codes.

Categories of "nonclass" errors appear on the following page.

Interpreting "Nonclass" Errors

Besides class errors, the system console also displays the following types of errors:

Run-time codes
DCC error
High priority machine check (HPMC) detailed errors (XXF0-XXFF)
Log file errors
SYSGEN messages (I/O, MISC, LOG, SYSFILE)
Outerblock messages
SERVE messages
Other messages
Scanner messages
Boot tape messages
LANGINST messages

* Multiprocessor errors

These error messages appear after the class errors in this chapter, in the same order shown in the list above. If unlisted errors occur, call your Hewlett-Packard support representative.
