Strange Characters from ILOM

Hello,

I have an x86 server with an ILOM connection that produces strange characters when I perform a start /SP/console, see below:

Code:
Oracle(R) Integrated Lights Out Manager


Version 3.0.16.10.a r68533

Copyright (c) 2011, Oracle and/or its affiliates. All rights reserved.

-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y

Serial console started.  To stop, type ESC (

 rootÀððóteótcóîít0±*£*
                        rootÀððóteótcóîít0±*£*
                                               rootÀððóteótcóîít0±*£*

So every time I press enter, rootÀððóteótcóîít0±*£ appears.
This is actually the has prompt and I can if i enter ls for example, I DO get an output:

Code:
rootÀððóteótcóîít0±*£*ló

                                                                                                                                        äeöiceó*************liâ*****************óùóteí
                          rootÀððóteótcóîít0±*£*

Its just that the output seems to be in the wrong characters.
Has anyone experienced this with ILOM (or ALOM even) and can provide some assistance?
From the public IP, I can telnet to the node and do not experience this problem.

Here is the output of eeprom from the public ip if it helps:
Code:
# eeprom
ata-dma-enabled=1
atapi-cd-dma-enabled=0
ttyb-rts-dtr-off=false
ttyb-ignore-cd=true
ttya-rts-dtr-off=false
ttya-ignore-cd=true
ttyb-mode=9600,8,n,1,-
ttya-mode=9600,8,n,1,-
lba-access-ok=1
prealloc-chunk-size=0x2000
boot-args=
nvramrc=." ChassisSerialNumber USM72106D8 " cr 
keyboard-layout=US-English
console=ttya

Please let me know.

how are you connectetd to the server (serial or ssh)? which OS is running on your server? have you tried to use the virtual KVM from the web-gui to see the system console?

Hi DukeNuke,

Thanks for the reply and the questions!
I get the error when connected directly to the serial port and when connected connected to the network management port over the internal network via ssh.

If I try to connect via the remote console web gui however, I get an error message saying :
Code:
/boot/solaris/bootenv.rc: syntax error on line 20

My OS is SunOS 5.10 Generic_144501-19 i86pc i386 i86pc
The server is an x4270_M2.

Any thoughts?
/Kerry

I'd suggest looking at the baud rate and parity setting of the ILOM and/or your serial terminal device. The output that you posted typically looks like either a baud rate or parity bit mismatch.

I don't know this server hardware but perhaps when you switch from talking to the console to talking to the ILOM the baud rate or parity bit changes.

Once connected to the ILOM try a different baud rate and/or parity setting on your serial device to see if you can suddenly make sense of it.

if it is the same output (even in a ssh session) i don't think it is the terminal settings... to me it looks like the OS is not bootet clean and is giving strange output... i would monitor a complete powercycle over the virtual KVM from the ILOM to check for errors during startup... there is clearly an error in your bootenv.rc file, so you should check this file also (if the os is not booting you've to use a DVD to boot the server).

Hi Guys,

Thanks for your help and suggestions!
I've checked and double checked, but I dont see any strange messages or errors during a power cycle (maybe human error and I keep missing it?) and the reset /SP/console does not help.

The bootenv.rc file shows no strange characters when I check it with vi:
Code:
# vi /boot/solaris/bootenv.rc
"/boot/solaris/bootenv.rc" 23 lines, 645 characters

Do you think there is some parameter missing from like 20? i.e.:
Code:
setprop boot-args

The only information I have on this parameter is from the manpage on eeprom:
Quote:
boot-args

Holds a string of arguments that are passed to the boot
subsystem. For example, you can use boot-args=' -
install dhcp' to request a customer jumpstart installa-
tion. See boot(1M), kadb(1M) and kernel(1M).
Do you know of something further I can try?

BR,
Kerry
