Hi all, I am trying to load kernel module ipmi_si, while failed with error "No such device", truth is I can find file in ../kernel/drivers/char/ipmi/ipmi_si.ko. So why I can't load it? Steps: # ls -l /lib/modules/2.6.32-573.el6.x86_64/kernel/drivers/char/ipmi/ipmi_si.ko -rwxr--r--. 1 root root 93080 Jul 23 2015 /lib/modules/2.6.32-573.el6.x86_64/kernel/drivers/char/ipmi/ipmi_si.ko # modprobe ipmi_si FATAL: Error inserting ipmi_si (/lib/modules/2.6.32-573.el6.x86_64/kernel/drivers/char/ipmi/ipmi_si.ko): No such device # lsmod |grep ipmi ipmi_devintf 7729 0 ipmi_poweroff 8532 0 ipmi_watchdog 17874 0 ipmi_msghandler 38701 3 ipmi_devintf,ipmi_poweroff,ipmi_watchdog # ipmitool Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory What should I do if I want to setup IPMI on my centos host? -- Regards Frank Yu
