If an IP maps to 2 different MAC addresses the arp table will only point
to 1 of the MAC addresses. So you will either have IPMI working, and
server NIC not working or the oposite. Depending on if BMC NIC or Server
NIC reply to the arp request first.

You have to configure the Server NIC and BMC with different IP
addresses.
