I am a partner pre-sales SE, trying to help one of our larger clients inventory all of their PowerPath licensing for EMC maintenance purposes.  Some licenses have been installed in a licensing server, so those are easy.  But, so many of the others have been installed on individual servers that may or may not still be in use.

Is there a good methodology for identifying all PP licensing throughout an enterprise?  Is there a way, from the storage arrays' perspective, which hosts have PP installed (and which do not)?

Thanks in advance,

Eric
