hpnmi failed to load

I have a new out of the box HP ML350 Gen9 server that I have installed ESXi 5.5 U2 onto.  This is the HP ISO from the VMWare site I installed--

VMware-ESXi-5.5.0-Update2-2403361-HP-550.9.2.27-Mar2015.iso

As ESX boots up I see an error that says hpnmi failed to start. ESX has booted and I'm able to use iLO to access the server through vSphere.  What is it that hpmni manages?  Do I need to manually update something on the server?

Thanks.
