Hi Wayne: I checked the Systems Management DVD and couldn't find a Dell version of IPMI Tool. Instead, I use some online tool to update the ipmitool. I further run the commands in my Cent OS:
[r...@gr3 ~]# ipmitool sdr Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory Get Device ID command failed Unable to open SDR for reading Sounds like my BMC fireware hasn't loaded successfully on my PowerEdge R710, because /dev/ipmi/0 couldn't be found. Or because my OS is Cent OS? Besides, I also checked what you said about those disabled sensors. I think you are right, because " Dell does not provide support for any internal sensor marked *disabled* or *not readable* when using the command *ipmitool sdr*." In order to further track the problem, I also checked the available ipmi module on my Cent OS, I get nothing returned of the following command: #lsmod | grep ipmi In a word, I'd like to know the answer of the following questions: 1. From the output of ipmitool sdr, can I ensure that the drivers for BMC haven't been installed(or supported) in my Cent OS? If so, where can I get those drivers for my CentOS? 2. Since currently, no ipmi modules is installed on my CentOS, where can I find and install those ipmi modules on my CentOS for Dell PowerEdge R710?
