I have a 1950-III 1U on the floor here that I'm loading. After configuring IPMI in the BIOS, I can: [2:6:306]root@strike:~> ipmitool -I lanplus -U root -H 192.168.221.160 shell Password: ipmitool> power on Chassis Power Control: Up/On Now. strike is not the 1U in question... and does not, in fact, have IPMI of it's own, but it can talk to the 1950-III, but... [1:1:301]root@test1:~> dmesg | grep ipmi ipmi0: KCS mode found at io 0xca8 on acpi ipmi0: KCS error: ff ipmi1: <IPMI System Interface> on isa0 device_attach: ipmi1 attach returned 16 ipmi0: IPMI device rev. 0, firmware rev. 2.2, version 2.0 ipmi0: Number of channels 4 ipmi0: Attached watchdog ... and it will respond to local use of the ipmi tool. Serial console works --- although it seems like it has a finite buffer and too much output overflows the buffer (flow control doesn't seem to fix this). You also have to custom compile the kernel and boot blocks to use COM2 (sio1) as the console. The BIOS seems to have settings to make the external serial port COM2 and use COM1 for IPMI, but the settings don't work. You need to use COM2. While you're at it, the default speed is 57600 (might as well compile in that default, too). The R200's that I have also seem to work fine. I haven't tested serial consoles with them --- but it's on the list. Curiously, IPMI shares the ethernet ports with the onboard ethernet controllers without FreeBSD's knowledge. It does use a different MAC address. It is also apparently capable of using vlans (haven't tested this yet). I'm most nervous about how this might behave if the port was being nailed with traffic --- but I can't easily test this to my satisfaction. What controls the contention for the port between whatever IPMI magic is going on and the OS use of the port? Anyways... the really cool thing about IPMI is that it's cheap enough to be included. The original poster spoke of a PCI card (likely one of the management cards) --- these are expensive options --- especially if you don't need graphics or remote media.
