We have a cluster of SuperMicro's that I'm trying to get IPMI working on st we can send power-cycle commands to each when they hang. They are running various flavors of RedHat. All hosts are on the same subnet.
SuperMicro comes with their own ipmi toolset. It includes a GUI IPMIView and ipmiconfig. All hosts have an IPMI card, we're using the NIC farthest to the left (facing the back) and BIOS's are set as per the manual. The GUI allows me to manually add a host but there doesn't seem to be a way to tie a MAC to the host. Using ipmicfg, I can specify a gateway, add an IP, separately add a MAC, turn on gratuitous ARP and a few more things. Back in the GUI, there's a discovery mechanism but it never picks up anything. When trying to click on the hosts I manually add, it always comes back "Device is off-line" So I then installed ipmitools from sourceforge and tried to play with it on the command line but it doesn't see a /dev/ipmi0 or /dev/ipmi/0 or i /dev/ipmidev. I tried mknod'ing a device (-m root, c 253,0) but that didn't help. SuperMicro apparently creates a /dev/ipmikcs device (major,minor #=10,173) so I tried just linking /dev/ipmi0 to that. No joy. Also tried issuing ipmitool commands from a cluster (on a different network) that does work, pointing to the supermicro cluster but it can't connect. I'm not quite sure where to look at this point. Anyone have any ideas? TIA
