Red Hat Bugzilla – Bug 141364
IPMI on Dell PowerEdge 2850 do not work with redhat kernel
Last modified: 2007-11-30 17:07:05 EST
Description of problem:
IPMI do not work on Dell PowerEdge 2850 with the default kernel
RHEL 3. According to
these machines need OpenDPMI driver versjon 33 or newer and the
ipmi_si_drv kernel module. This driver is available from
<URL: http://sourceforge.net/projects/openipmi >.
IPMI is needed to get HW status info from the machine. We need
to be able to monitor and detect problems with this type of
Version-Release number of selected component (if applicable):
This fails every time.
Steps to Reproduce:
1. modprobe ipmi_si_drv - fail
2. modprobe ipmi_kcs_drv - fail
3. modprobe ipmi_devintf - loads, but fail to find the correct IP
I got these messages in /var/log/messages
Nov 30 18:17:59 delltest kernel: ipmi: message handler initialized
Nov 30 18:18:00 delltest kernel: ipmi: device interface at char
Nov 30 18:22:02 delltest kernel: ipmi_kcs: SPMI table not found.
Nov 30 18:22:02 delltest kernel: ipmi_kcs: No KCS @ port 0x0ca2
Nov 30 18:22:02 delltest kernel: ipmi_kcs: Unable to find any KCS
According to the article, the port to use is 0xca8, and not 0x0ca2.
The newer driver will detect the correct port to use using DMI
I expected a working kernel driver and access to a ipmi device.
There is a command line tool to access the IPMI device available
from <URL:http://ipmitool.sourceforge.net/>. It can be used to
the device and driver.
This bug has had "NEW" status for quite some time... Confirmed that it still
doesn't work with kernel 2.4.21-32.0.1. Excepting lm_sensors, IPMI is the only
_open_ standard for hardware monitoring that I know of, and IPMI is far better
than lm_sensors and proprietary vendor software, which tends to be large and
intrusive. Providing of course that the machine has an IPMI device, which
expensive servers like the Dell PE2850 usually do. Any chance that Red Hat will
appreciate working IPMI support in the kernel and upgrade the modules?
IMO one should expect an enterprise OS to be able to harness enterprise-type
hardware, also when it comes to monitoring features, especially if the hardware
complies to open standards.
This bug is filed against RHEL 3, which is in maintenance phase.
During the maintenance phase, only security errata and select mission
critical bug fixes will be released for enterprise products. Since
this bug does not meet that criteria, it is now being closed.
