Disappearing LUNs?

Did an ONTAP upgrade from to 7.3.3, went fairly smooth.  When I rebooted my Windows 2003 cluster I started seeing some weird LUN behavior.  A LUN was listed, but showed that it wasn't formatted or accessible.  I unmapped the LUN, remapped it, rescanned, all the normal troubleshooting activities without success.  Finally rebooted the cluster and that LUN came back online and another one now is exhibiting the same symptoms.  this seems a little bizzaro to me, any suggestions?

Just rebooted the cluster... again, and this time everything came back online ok.  Going to chalk this one up to Murphy and chance unless there is someone out there who knows what might have happened.
