Sun Fire X4100 - Serial redirection is very unstable.
Dear all,
I am having new troubles with X4100 hardware.
I am setting up console serial redirection and it does not work properly. Here is what I am doing :
- I set up the SP serial port speed to 115200 and commitpending to true.
- I set up console redirection port speed accordingly in the BIOS.
When I do a start /SP/console I only get weird chars on screen (symptom of a speed configuration mismatch). Moreover, when I reboot the server if I have a serial console started , the BIOS does not boot successfully, only '033' is being printed on the bottom right of the screen. I can to stop serial console redirection and to reset the server...
I am using bios version 1.1.8.
Can anyone help ?
Many thanks.

Eric,
Generically (and generally, as well) CLI serial connections are done at 9600 baud.
That's the default that the serial ports have, out-of-the-box.
The ILOM manual for your system gives guidance how to configure such a connection.
( that's document # 820-0280 from Docs.Sun.Com )
( and the document is linked from the X4100 page in the SSH )
See section 2.1.2 in that document.

I hope that long link doesn't break as it wraps to two lines.

Thanks for your help.
I was using the same procedure. The fact is I didn't see that SP serial port speed was limited to 57600 bps. It is strange the BIOS console redirection speed can be up to 115200 bps although SP serial port max speed is limited to 57600 bps.
It is too bad this feature is not available as Sun Fire V40z SP, which is an older model, can have a serial port speed up to 115200.
