Just banged my head against a wall for hours trying to get a new Service Profile associated with a new blade.  It kept retrying to “Configure resolve identifiers”.  Finally stumbled on an obscure support forum article just when I was about to give up and call Cisco TAC…

TLDR version…

If the UCS domain (FIs) have been registered with UCS Central, you can’t associate service profiles with UCS Manager.  If it looks like this in UCS Manager with Registration Status showing Lost Visibility…

Your UCS Domain is either having problems connecting to UCS Central, or UCS Central is burnt… or dead…  Troubleshoot why it has lost connectivity, or if UCS Central is gone, click the red circled Unregister From UCS Central, and proceed.

If you see a nice green check box, that means UCS Central is present, and you should use it to associate the Service Profile, not UCS Manager.

In this case, the customer deployed UCS Central to play with, decided they didn’t need it, and removed it from their environment, but kept it registered.  So I unregistered it, and the Service Profile associated nice and easy.
