While not ideal, I just copied the contents of the extracted 2014 support pack into my repository, rebuilt the catalog, and now while the actual support pack shows as invalid, the individual components are available for updates.
I hope they aren't moving away from VCA / VCR to the HP SUM. I tried it and was very unhappy. When trying to upgrade 15+ servers over a WAN, each inventory took FOREVER, and that was just to see what updates were available. And after the inventory it tried to install a few updates that were not applicable to that server (they failed, but now I had a failed status on that server even though it was done).
With SNMP being deprecated in 2012, it seems to me HP is moving away from the system management homepage in general. I have one VM host i upgraded to 2012 and I can't get SMH to work under SNMP mode for anything. Researching it looks like the G8's now have an "agentless" alerting system built into the iLo rather than the SNMP agents on the SMH. Based on my SUM experience I'm not very confident they are actually any better than the good old SNMP.
