I have a discovery and inventory that uses the Device Type filtering for ESXi and it finds my hosts, but the R630s all show up with a question mark, where the FX2/R630C show with a green check mark. Also I noticed that none of the R630s show up under systems update. I have installed the vib for OMSA via Update Manager and also configured SNMP. 

Any ideas? I'm sure these servers must need a firmware update by now!
