Newer Supermicro IPMI interfaces come configured by default in “failover” mode which means that the IPMI will bind to either the dedicated IPMI NIC port or share with one the the machine NIC ports.
This can cause IPMI to come up on wrong NIC and hence be inaccessible if the dedicated NIC doesn’t detect a link.
You can use ipmitool to change this behavour
First query the current setting:
ipmitool raw 0x30 0x70 0x0c 0
The result will be one of the following
0x00 = Dedicated
0x01 = Onboard / Shared
0x02 = Failover
Next to configure it you can use one of the following.
For older models:
ipmitool raw 0x30 0x70 0x0c 1 1 0
For X9 motherboards:
ipmitool raw 0x30 0x70 0x0c 1 0
