diag ouput to RSC on V880 ?
I've just spent a week getting all our Sun boxen hooked up to a private network for the RSC/SC ports and redirecting console I/O to these RSC ports. All appeared to be working fine - telnet into the RSC, halt, diddle the OBP, printenv, reboot - true console access via this RSC card.
Then we lost a CPU board on the V880. The FE shows up and proceeds to hook his laptop up to serial A. I explain that the RSC is accessible from this "console server" workstation in the corner. He says that diag output will come out only on serial A. And, sure enough, that appears to be the case.
Nothing I can do will make those initial diag messages come to the RSC. It's only after several minutes after power on that it hits some point in the OBP that it starts sending to the RSC attached console session.
Yes, we tried "diag-out-console=true", input & output-device=rsc-console,
nothing gets the hardware diag output to the RSC.
Am I missing something here ? If diag output bypasses the RSC card, what's the use of having a remote system controller ? A sizeable percent of the times that you'll need remote console access will be for hardware related issues where diagnostic output is indispensable.
The Sun documentation for the RSC/SC leaves a lot to be desired.
Can someone clarify, please ?
thanks,

Hello Don,
I just tried if the diag messages are redirected to the RSC port. My system is a E250, which uses a less advanced RSC card (no battery backup or modem port).
Yes, the messages appeared on the ethernet port of the RSC. The system is located in the basement, using the network instead of a serial connection is just more convenient for me. I'm sure that the serial port of the RSC works in the same way.
<i>Yes, we tried "diag-out-console=true", input & output-device=rsc-console, nothing gets the hardware diag output to the RSC.</i>
According to the Online Help (RSC 2.2.3), the settings are
<b>diag-console rsc</b>
setenv input-device rsc-console
setenv output-device rsc-console
(The settings for the E250 are slightly different).
This is from the User's Guide (Part No. 816-3314-12)
<table border="0" align="center" width="90%" cellpadding="3" cellspacing="1"><tr><td class="SmallText"><b>Quote:</b></td></tr><tr>& lt;td class="quote">
diag-console rsc|ttya
This command directs power-on self-test (POST) output to either RSC (1) or ttya (0).
This command takes effect after the next server reset.
</td></tr></table>

Hello,
Have same kind of problem with sunfire 480. I am able to connect to system console via ethernet rsc port. But not with modem port.<img src="images/smiley_icons/icon_sad.gif" border=0 alt="Sad"> Dialing in works, i can see login prompt but it is all i can do.
Oboot variables are changed to (as stated in SunFire V480 Server Administration guide):
output-device=rsc-console
input-device=rsc-console
diag-out-console=true
With keyboard/screen/false settings i had been able to use modem rsc (login in, run cli commands) - but without console redirection (i'm not interested in serial rsc port).
RSC manual gives uncorrect settings in comparison to sunfire 480 adminguide - its really annoying.
The best thing is 2 years before it WAS working. Unfortunately noone remember how to setup it again:(
UPDATE: it was tricky:] i've just needed to change ascii terminal charasters to 7-bit instead of default (8bit i guess). And the funny thing is that winhyperterminal gives me different settings almost every time i run it:)
So i've solved it myself but... i'm curious if i can see POST messages via modem. Enyone tried it?
