Interpreting AP Error and Informational Messages
The AP provides two classes of messages. A message that is followed by
(APERR XX) is an error message. "XX" indicates the error number. A
message that is followed by (APMSG XX) is an informational message,
although it can indicate a potential error. Error and informational
numbers may be duplicated; for example, there is both an APERR 01 and an
APMSG 01.
Error Codes and Error Messages
--------------------------------------------------------------------------------------
MESSAGE Unable to verify assertion of RESET SYS backplane signal (APERR
01)
CAUSE This message, displayed during execution of the RS command, means
that the backplane signal RESET_SYS- is not asserted when the AP
attempts to reset the SPU.
This error might be caused by any one or a combination of four
conditions.
Failure of the AP drive circuitry causes this error to be
detected, and the SPU is not reset.
The circuitry that permits the AP to read this line may have
failed. If this is the case, the error message is displayed, but
the SPU is reset in the proper manner.
The CIO backplane may contain a short between the RESET_SYS- line
and another low impedance line that is driving a high-logic level.
Some other device connected to the RESET_SYS- line may be driving
a high-logic level that the AP cannot overdrive.
--------------------------------------------------------------------------------------
MESSAGE RESET_SYS backplane signal asserted, but unable to verify SPU
deassertion of PPON backplane signal (APERR 02)
CAUSE This message, generated during execution of the RS command,
indicates that the PPON backplane signal is not deasserted within
2 seconds after the RESET_SYS- line is asserted.
This error may be caused by three conditions. If the receiver,
which senses this state of this line on the AP, has failed, the
system displays the message. The SPU resets normally. The AP
also resets itself as soon as the RS command has completed, if
this is the cause of the failure.
If the wiring between the assembly that receives RESET_SYS- and
the AP is defective, neither the SPU nor AP resets.
If the portion of the power system that generates PPON is
defective, the SPU does not reset, and the AP probably does not
reset.
--------------------------------------------------------------------------------------
MESSAGE PPON not reasserted by SPU after RESET_SYS deassertion (APERR 03)
CAUSE This message, displayed by the RS command, means that PPON has not
reasserted within 2 seconds after being deasserted. Once this
occurs, the AP becomes insensitive to being reset by the
deassertion of PPON.
This error is most likely the result of a fault in the assembly
that generates the PPON signal.
--------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------
MESSAGE Unable to verify assertion of TOC_SYS backplane signal (APERR 04)
CAUSE Information not currently available.
--------------------------------------------------------------------------------------
MESSAGE AP Self-Test failed subtest xx (APERR 05)
CAUSE This message is displayed when a failure occurs during the
execution of AP self-test. XX gives the decimal number of the
failing subtest.
--------------------------------------------------------------------------------------
MESSAGE AP failed subtest xx of idle Self-Test. (APERR 06)
CAUSE This message is displayed when the idle self-test fails.
Since idle self-test executes whenever the AP microprocessor has
idle time, this message may appear at any time, in any AP context,
including during console mode operation.
--------------------------------------------------------------------------------------
MESSAGE AP failed subtest xx of prior idle Self-Test. (APERR 07)
CAUSE This message is displayed when a switch in modes is made after
idle self-test has failed previously.
--------------------------------------------------------------------------------------
MESSAGE Permitted accesses to NVM exceeded. (APERR 08)
CAUSE This message is displayed each time that the AP accesses NVM after
the counter in NVM indicates that the permitted number of accesses
to the last block of NVM has been exhausted. The AP should be
replaced at the next visit by HP service personnel. The NVM may
survive for up to 20,000 more accesses after this message begins
to occur, or it may fail almost immediately.
--------------------------------------------------------------------------------------
MESSAGE CRC error on NVM. (APERR 09)
CAUSE This message is displayed when the AP has exhausted the permitted
number of accesses to all blocks of NVM. The default settings for
NVM parameters are used. Notify your HP service personnel. The
AP must be replaced.
--------------------------------------------------------------------------------------
MESSAGE Illegal command, type HE for help. (APERR 10)
CAUSE The first two characters entered in a command line for the AP
command interpreter are not an AP command. Help displays all
legal commands.
--------------------------------------------------------------------------------------
MESSAGE Expecting "Y" or "N" (APERR 11)
CAUSE The AP is expecting one of the letters Y or N, in either uppercase
or lowercase, as the reply to the query displayed on the screen.
--------------------------------------------------------------------------------------
MESSAGE Expecting "H" or "L" (APERR 12)
CAUSE The AP is expecting one of the letters H or L, in either uppercase
or lowercase, as the reply to the query displayed on the screen.
H stands for high, and if chosen, causes the specified signal to
be set to the high voltage level, which is nominally +9 Volts
referenced to ground. L stands for low, and if chosen, causes the
specified signal to be set to the low voltage level, which is
nominally -9 volts referenced to ground.
--------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------
MESSAGE Command may not be executed by a remote user. (APERR 13)
CAUSE The command entered is a valid AP command, but is intended for use
from the local console port (port T0) only. No action has been
taken.
--------------------------------------------------------------------------------------
MESSAGE Your selection is outside of the legal range. (APERR 14)
CAUSE Either numeric data has been entered when alphabetic input is
expected (or vice versa), or the value of numeric data entered is
outside of the permissible range of values.
--------------------------------------------------------------------------------------
MESSAGE Command may not be executed by a local user. (APERR 15)
CAUSE This command is a valid AP command, but is intended for use from
the remote support modem port (port T1) only. No action has been
taken.
--------------------------------------------------------------------------------------
MESSAGE Expecting "S" or "M" (APERR 16)
CAUSE The only permissible input at this time is the letter S for single
or the letter M for multiple. They may be entered either in
uppercase or lowercase.
--------------------------------------------------------------------------------------
MESSAGE Syntax error. (APERR 17)
CAUSE Any error other than those covered by error messages APERR 18 and
APERR 19 when using the DM, AM, DD, or AD commands, causes this
error message.
--------------------------------------------------------------------------------------
MESSAGE Illegal hexadecimal entry. (APERR 18)
CAUSE If any of the hex parameters entered with the DM, AM, DD, or AD
commands are not valid hex numbers, this error message is be
output.
--------------------------------------------------------------------------------------
MESSAGE Illegal address or address range. (APERR 19)
CAUSE Attempting to address outside the legal range of addresses with
the DM, AM, DD, or AD commands causes this error message to be
given.
--------------------------------------------------------------------------------------
Informational Messages
--------------------------------------------------------------------------------------
MESSAGE AP self-test passed. (APMSG 01)
CAUSE AP self-test was executed, and it has passed. The message is
accurate in almost all cases; however, it is possible that the
message will appear without the test having executed to
completion. This case can be detected by observing whether the
full complement of subtests has been executed in the proper order.
AP self-test detects only approximately 70 percent of the faults
on the AP.
--------------------------------------------------------------------------------------
MESSAGE SPU hardware was successfully reset. (APMSG 02)
CAUSE This message indicates that the AP did not enter the three
possible error states. It does not mean that the AP has somehow
detected that the processor has restarted or that it was cleared,
for example. The AP has no way to determine the internal state of
any other assembly in the SPU.
--------------------------------------------------------------------------------------
MESSAGE Console terminal not set to 9600 bits per second. Console port
will operate at xxxx bits per second. (APMSG 03)
CAUSE The AP senses the setting of the console connected to local
console port using ENQ/ACK. The console should be operating at
9600 bits per second. If it is operating at 4800, 2400, 1200, 600
or 300 bits per second, the AP senses this and operates the port
at this baud rate.
If the above message appears on the terminal screen, the AP and
the terminal are both set for the same baud rate. If the terminal
is accidentally set for other than 9600, the above-referenced
procedure should be followed to reset the terminal and AP for
9600. If the terminal is set for 9600, the AP or the terminal is
defective.
--------------------------------------------------------------------------------------
MESSAGE String was truncated to 24 characters. (APMSG 04)
CAUSE You can enter only up to 24 displayable characters in the answer
to the query on the screen. All characters past the twenty-fourth
were discarded. No action is necessary if the resulting truncated
string is acceptable as the answer to the query. If the resulting
string is not acceptable, continue command execution until you are
again prompted for the string and enter the new string.
--------------------------------------------------------------------------------------
MESSAGE AP configuration lost. Use CA and ER commands to recover. (APMSG
05)
CAUSE If this message recurs after each reset, power on, or self-test
execution, the AP is defective.
