Stian, I believe the port should be 0xCA2, not 0xCA0. According to the docs, it does have IPMI support, but it would be only local (no IPMI LAN). Try modprobe ipmi_si type="kcs" addrs="0xca0" or just modprobe ipmi_si Andy -----Original Message----- From: Stian Jordet [mailto:liste at jordet.net] Sent: Monday, October 01, 2007 3:58 AM To: lm-sensors at lm-sensors.org Cc: yani.ioannou at gmail.com; Cress, Andrew R; slava at nsys.by Subject: IPMI and ipmisensors on an Intel SC450NX Hi, Sorry, this is going to be long and probably cross-posted too many places, but it isn't easy to know where to direct this! The persons in the CC-field I have found after searching on the net, hoping any of them have some bright ideas! I've used the weekend (again!) trying to get sensors working on my good old Intel SC450NX server, with no luck. First of all, I'm not even sure what IPMI version this system has. I found this mail: http://sourceforge.net/mailarchive/message.php?msg_id=74A9A71929931E4096 7CA9F27B1D7396014D46A2%40hdsmsx401.amr.corp.intel.com where an Intel employee thinks it is IPMI 1.0, and either way it should work with the ipmi_imb emulation driver, which supposedly uses the same interface as the original Intel Server Manager uses. I'm still afraid it is IPMI 0.9 I have. I have updated both BIOS, BMC and FRUSDR (whatever that is) to the latest available versions. dmidecode doesn't have any traces of ipmi. But lm-sensors sensors-detect reports this: [...] Probing for `IPMI BMC KCS' at 0xca0... Success! (confidence 4, driver `ipmisensors') Probing for `IPMI BMC SMIC' at 0xca8... No [...] which at least gave me some hope. The ipmisensors page says I need to use ipmi_si before loading the ipmisensors-module. I then tried loading some modules... root at buick:~# modprobe ipmi_si IPMI System Interface driver. ipmi_si: Unable to find any System Interface(s) FATAL: Error inserting ipmi_si (/lib/modules/2.6.21/kernel/drivers/char/ipmi/ipmi_si.ko): No such device root at buick:~# modprobe ipmi_si type="kcs" addrs="0xca0" IPMI System Interface driver. ipmi_si: Trying hardcoded-specified kcs state machine at mem address 0xca0, slave address 0x0, irq 0 Could not set up I/O space ipmi_si: Unable to find any System Interface(s) FATAL: Error inserting ipmi_si (/lib/modules/2.6.21/kernel/drivers/char/ipmi/ipmi_si.ko): No such device After applying ipmi_emu.diff from http://openipmi.sf.net, I tried the earlier promised ipmi_imb driver: root at buick:~# modprobe ipmi_imb ipmi: can't create user -22 FATAL: Error inserting ipmi_imb (/lib/modules/2.6.21/kernel/drivers/char/ipmi/ipmi_imb.ko): Invalid argument Not looking that good... What does "can't create user -22" mean? I found this in my dmesg: pnp: 00:01: ioport range 0xca0-0xca7 has been reserved Which gave me hope that pnp was "locking" the ipmi addresses. Booted with pnpbios=no and pnpacpi=off and even acpi=off, no difference. I ran the FRUSDR utility from a boot disk, and got this output: a:\>frusdr /p /d fru FRU & SDR Load Utility Version 3.4 FRU IMBDEVICE on bus FFh, IMB address 20h, LUN 00 Display Header Area Common Header Area (Version 1, Length 8) Internal Area Offset = 01h Chassis Area Offset = 1Ah Board Area Offset = 1Eh Product Area Offset = 26h Multirecord Area Offset = 00h PAD = 00h CHECKSUM = A0h Don't know what any of this means, except it kinda says it does have a "imbdevice" (Which I had some hopes the ipmi_imb driver would support...) Ok, I found this http://bubble.nsys.by/projects/ipmi/ and this http://archives.andrew.net.au/lm-sensors/msg29983.html on the web, showing at least two attempts trying to get bmcsensors working with IPMI 0.9 (if that's what my system has), but I haven't found any sign of success or not. I am especially curious as to whether Yani's attempt to make bmcsensors working with IPMI 0.9 will have any effect now that ipmisensors seems to use ipmi_si and OpenIPMI does not suppoert IPMI 0.9... Anyone have any bright ideas where to look next? Or am I really out of luck? Thanks. Regards, Stian
