I am using an SGI 1100 U1 server with p3 at 866*2 and ServerWorks LE North&South Bridge. (CNB30LE & OSB4) According to SGI's tech sheet, BMC is connected to the South Bridge SMB which provides IPMI functionality. I am using Ubuntu 6.06 (Dapper Drake) on kernel 2.6.17 with the openIPMI(v39) and ipmisensors patch. And I have installed lm-sensors 2.9.x deb package which was provided by ubuntu. Sensors keeps telling me it can't find any sensors and I have no idea why. (may be incorrect kernel patch or config?) My kernel patch list is as so. 1. OpenIPMI from http://openipmi.sourceforge.net <http://openipmi.sourceforge.net/> A. linux-i2c-2.6.17-v39.0.diff B. linux-ipmibase-2.6.17-v39.0.diff C. linux-ipmismb-2.6.17-v39.0.diff 2. IPMIsensors from http://bmcsensors-26.sourceforge.net <http://bmcsensors-26.sourceforge.net/> A. ipmisensors-20060805-0622.diff The following is my lsmod readings root at sigma:/usr/src/patch# lsmod Module Size Used by i2c_isa 5120 0 i2c_dev 9248 0 quota_v2 9856 2 ipv6 259168 21 ipmisensors 18792 0 ipmi_msghandler 35872 1 ipmisensors parport_pc 36048 0 lp 12000 0 parport 36808 2 parport_pc,lp i2c_piix4 8912 0 floppy 60304 0 i2c_core 27040 3 i2c_isa,i2c_dev,i2c_piix4 sworks_agp 9600 0 agpgart 32744 1 sworks_agp e100 35044 0 mii 5888 1 e100 psmouse 38696 0 serio_raw 7140 0 pcspkr 3136 0 evdev 9984 0 ext3 137160 5 jbd 58228 1 ext3 mbcache 8900 1 ext3 ide_generic 1408 0 [permanent] ohci_hcd 21508 0 usbcore 128668 2 ohci_hcd ide_cd 40256 0 cdrom 37456 1 ide_cd ide_disk 16736 8 serverworks 8968 0 [permanent] generic 4516 0 [permanent] thermal 13192 0 processor 23176 1 thermal fan 4708 0 vga16fb 12744 0 cfbcopyarea 3968 1 vga16fb vgastate 9632 1 vga16fb cfbimgblt 3072 1 vga16fb cfbfillrect 4320 1 vga16fb It seems that the ipmisensors and ipmi_msghandler have successfully loaded. And the following is the output of sensors-detect. root at sigma:/usr/src/patch# /usr/local/sbin/sensors-detect This program will help you determine which I2C/SMBus modules you need to load to use lm_sensors most effectively. You need to have i2c and lm_sensors installed before running this program. Also, you need to be `root', or at least have access to the /dev/i2c-* files, for most things. If you have patched your kernel and have some drivers built in, you can safely answer NO if asked to load some modules. In this case, things may seem a bit confusing, but they will still work. It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing. We can start with probing for (PCI) I2C or SMBus adapters. You do not need any special privileges for this. Do you want to probe now? (YES/no): Probing for PCI bus adapters... Use driver `i2c-piix4' for device 00:0f.0: ServerWorks OSB4 South Bridge Probe succesfully concluded. We will now try to load each adapter module in turn. Module `i2c-piix4' already loaded. If you have undetectable or unsupported adapters, you can have them scanned by manually loading the modules before running this script. To continue, we need module `i2c-dev' to be loaded. If it is built-in into your kernel, you can safely skip this. i2c-dev is already loaded. We are now going to do the adapter probings. Some adapters may hang halfway through; we can't really help that. Also, some chips will be double detected; we choose the one with the highest confidence value in that case. If you found that the adapter hung after probing a certain address, you can specify that address to remain unprobed. That often includes address 0x69 (clock chip). Next adapter: SMBus PIIX4 adapter at 0e80 (Algorithm unavailable) Do you want to scan it? (YES/no/selectively): Client found at address 0x60 Some chips are also accessible through the ISA bus. ISA probes are typically a bit more dangerous, as we have to write to I/O ports to do this. This is usually safe though. Do you want to scan the ISA bus? (YES/no): Probing for `National Semiconductor LM78' Trying address 0x0290... Failed! Probing for `National Semiconductor LM78-J' Trying address 0x0290... Failed! Probing for `National Semiconductor LM79' Trying address 0x0290... Failed! Probing for `Winbond W83781D' Trying address 0x0290... Failed! Probing for `Winbond W83782D' Trying address 0x0290... Failed! Probing for `Winbond W83627HF' Trying address 0x0290... Failed! Probing for `Winbond W83697HF' Trying address 0x0290... Failed! Probing for `Silicon Integrated Systems SIS5595' Trying general detect... Failed! Probing for `VIA Technologies VT82C686 Integrated Sensors' Trying general detect... Failed! Probing for `VIA Technologies VT8231 Integrated Sensors' Trying general detect... Failed! Probing for `ITE IT8705F / IT8712F / SiS 950' Trying address 0x0290... Failed! Probing for `IPMI BMC KCS' Trying address 0x0ca0... Failed! Probing for `IPMI BMC SMIC' Trying address 0x0ca8... Success! (confidence 4, driver `bmcsensors') Some Super I/O chips may also contain sensors. Super I/O probes are typically a bit more dangerous, as we have to write to I/O ports to do this. This is usually safe though. Do you want to scan for Super I/O sensors? (YES/no): Probing for `ITE 8702F Super IO Sensors' Failed! (skipping family) Probing for `Nat. Semi. PC87351 Super IO Fan Sensors' Failed! (skipping family) Probing for `SMSC 47B27x Super IO Fan Sensors' Failed! (skipping family) Probing for `VT1211 Super IO Sensors' Failed! (skipping family) Do you want to scan for secondary Super I/O sensors? (YES/no): Probing for `ITE 8702F Super IO Sensors' Failed! (skipping family) Probing for `Nat. Semi. PC87351 Super IO Fan Sensors' Failed! (skipping family) Probing for `SMSC 47B27x Super IO Fan Sensors' Failed! (skipping family) Probing for `VT1211 Super IO Sensors' Failed! (skipping family) Now follows a summary of the probes I have just done. Just press ENTER to continue: Driver `bmcsensors' (should be inserted): Detects correctly: * ISA bus address 0x0ca8 (Busdriver `i2c-isa') Chip `IPMI BMC SMIC' (confidence: 4) I will now generate the commands needed to load the I2C modules. Sometimes, a chip is available both through the ISA bus and an I2C bus. ISA bus access is faster, but you need to load an additional driver module for it. If you have the choice, do you want to use the ISA bus or the I2C/SMBus (ISA/smbus)? To make the sensors modules behave correctly, add these lines to /etc/modules.conf: #----cut here---- # I2C module options alias char-major-89 i2c-dev #----cut here---- To load everything that is needed, add this to some /etc/rc* file: #----cut here---- # I2C adapter drivers modprobe i2c-isa # I2C chip drivers modprobe bmcsensors # sleep 2 # optional /usr/local/bin/sensors -s # recommended #----cut here---- WARNING! If you have some things built into your kernel, the list above will contain too many modules. Skip the appropriate ones! You really should try these commands right now to make sure everything is working properly. Monitoring programs won't work until it's done. Do you want to generate /etc/sysconfig/lm_sensors? (yes/NO): I'm not sure but it seems lm-sensors is looking for modprobe bmcsensors which doesn't exist on my system. (I have ipmisensors instead) There are no errors in dmesg. Any comments on this issue would be greatly appreciated. Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
