Hi all,
New to the list and (mostly) new to CentOS. We have just moved from running RHEL to CentOS on our main production servers.
Anyway, I am configuring a couple of new SunFire v20z servers here at the moment and trying to get the systems' management interfaces to work fully under CentOS.
First issue was trying to install the openipmi RPM from the CD that came with the SunFires, this RPM installs the source for the openipmi kernel drivers and then builds them as kernel modules. First I had to get the kernel source installed (i used the kernel SRPM to install, then did an rpmbuild to create the patched source directory), however I'm now receiving a whole bunch of errors whilst trying to compile the IPMI driver 'ipmi_devintf_src.c' file because of what looks to be incompatibilities with the kernel. My presumption is that this openipmi driver is intented for 2.4.x kernels.
So I moved on and discovered that openipmi is built into the 2.6.9-11.EL kernel which is installed by default. I tried inserting these modules: ipmi_devintf ipmi_msghandler ipmi_si ipmi_watchdog Which produced the following syslog output: Oct 5 00:02:00 langoria kernel: ipmi message handler version v33 Oct 5 00:02:00 langoria kernel: ipmi device interface version v33 Oct 5 00:02:03 langoria kernel: IPMI System Interface driver version v33, KCS version v33, SMIC version v33, BT version v33 Oct 5 00:02:03 langoria kernel: ipmi_si: Found SMBIOS-specified state machine at I/O address 0xca2 Oct 5 00:02:03 langoria kernel: IPMI kcs interface initialized Oct 5 00:02:07 langoria kernel: IPMI Watchdog: driver version v33
I thought, "Wonderful! It's working!", and was happy to see that the ipmi device existed: crw-r--r-- 1 root root 254, 0 Oct 4 23:27 /dev/ipmi0 (However, it seems like its always been there - not sure why. Doesn't CentOS use udev?)
I installed the userland ipmitool software and all was peachy.
...But my excitement and fun was ruined when I actually tried to use the tool: [root@langoria ~]# ipmitool sel Could not open device at /dev/ipmi0 or /dev/ipmi/0: No such file or directory Get SEL Info command failed
Seems like the OpenIPMI drivers aren't binding to the device?
Basically, I'm wondering if anyone has had any experience running openipmi on CentOS 4.1 running the default 2.6.9-11.EL kernel and can offer any assistance to me?
