Gabor, HP's server machines do not have a BMC unless an optional management daughterboard called "iLO2" is installed. If you have the purchase manifest for the machine, check for that.
When you reboot a machines with an iLO2, it displays BIOS messages offering you to setup the iLO2. Reboot the machine as many times as necessary for you to have carefully observed the entire BIOS startup sequence: do you see any mention of iLO2? If not, no BMC (which means it probably has a mistaken DMI table entry, Corey's alternative #1 below). If it _does_ have an iLO2 then go into its setup, make sure IPMI BMC is enabled, see if there are any other settings that might affect HW recognition behavior. >Bela< -----Original Message----- From: [EMAIL PROTECTED] on behalf of Gabor Ivanszky Sent: Tue 2007-03-06 8:34 AM To: Corey Minyard Cc: [email protected] Subject: Re: [Openipmi-developer] ipmi driver supported BMC's -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I tried the kcs_detect() hack, and the driver hung at insertion time. I also tried forcing type kcs, bt,smic combinating with different I/O addresses(default 0xca2, and 0x4e from DMI) still no success so at last my bet is that there is no BMC in my machine. There is no strong evidence, but the confusing specifications, and all the stuff we tried makes me think this. many thanks for your help and your time, Gabor Corey Minyard wrote: > Unfortunately, this is a difficult issue and very hard to resolve. > From what I can tell, it is one of the following problems: > > 1.
