Serial console configured ... break to DDB still doesn't work ..
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 so, I'm still missing a step here somewhere ... First, this is an HP Proliant Server ... I've tried using ssh and telnet to connect to iLO, and used 'vsp' for the virtual serial port ... Here's what I have so far ... kernel is built so that it uses COM2 (0x2F8) as comconsole, and I have the following in my /boot/loader.conf: hint.sio.0.flags="0x30" hint.sio.0.port="0x2F8" hint.sio.0.irq="3" console="comconsole vidconsole" comconsole_speed="115200" boot_multicons="yes" Now, I had missed a step from the handbook, and that was to configure my boot blocks for the change in com port ... or, rather, I added the settings to /etc/make.conf, 'cd /sys/boot; ...' and installed them, just forgot to do the bsdlabel ... type'd reboot, slap'd my forehead for not remembering, but, everything came up as expected ... so, does the hint.sio stuff above override the requirement to set things in /etc/make.conf and do bsdlabel? The handbook instructions seem to be from pre-6.x days as it is, as it still talks about configuring sio via the kernle config ... So, I reboot, on my VSP, I get all of the normal device probe stuff that one would expect, and, thanks to my getty on port ttyd0,I get a login prompt ... all great. Now, through telnet to ilo, I do: ^]send break nadda, doesn't drop me to the debugger ... so, I suspect that ilo is trapping the break and not passing it to the backend / DDB? Now, funny thing ... I did do a reset of iLO, which proceeded to drop the system into DDB ... so, somehow, I have to get iLO to send that break ... ? I'm double checking with ALT_BREAK_TO_DEBUGGER set, to see if I can get *that* to work ... but, if anyone has any thoughts on this, please, I'm all ears ... I'm sooooooo close ... - ---- Marc G.

The latter is dangerous depending on your serial console server device, or if you plug in a cable into the port on a running system...

Just FYI, "hints" aren't. Er, acpi ignores them. We found that if ACPI wants 2F8 on a given sio port, it was better ... er, only worked ;-) if we configured device.hints to match what ACPI expected. FYI, you might find "-dH" in /boot.config to be more useful that the console setting in loader.conf. It sets console=comconsole by default, but leaves you able to override it from the vid console if you are at the keyboard when it boots. Very useful. On Dec 16, 2006, at 9:34 PM, Marc G.
