Sometimes you need to make changes to your IPMI setup but you don’t want to take the machine offline to do it.
Supermicro offers a ipmicfg utility that will connect to the IPMI from within the running OS (Linux, ESX, etc) I needed to do this on ESXi. I copied the tarball over to ESXi (tmp works if you don’t plan on doing this a lot), unpacked it, and ran it as root.
Setting up the system service
Best way is to reset to defaults and clear FRU&LAN with SuperMicro native tool, like so:
1./ipmicfg-linux.x86_64 -fde
(All this may take a few seconds to take effect, so wait between commands!) Now turn off the DHCP setting restored from factory defaults with
1./ipmicfg-linux.x86_64 -dhcp off
then, restore your network settings with:
1./ipmicfg-linux.x86_64 -m $IP_ADDRESS
2./ipmicfg-linux.x86_64 -k $NETMASK
3./ipmicfg-linux.x86_64 -g $GATEWAY_IP
I’ve noticed, that sometimes, you need to reset BMC unit for it to take effect. You can reset it with:
1./ipmicfg-linux.x86_64 -r
You’ll have to configure the IP/Netmask/Gateway again with the same tool, but this is the only way I could make it work. OpenIPMI and IPMITools did not work for me on FreeBSD. I’ve tried resetting the password, cold resetting BMC, to no avail. However, they are good for setting IP and reading sensor data.
You can get the appropriate version for your OS from SuperMicro FTP
