Since the installation of a new server OES2015, I have the following error:

ndpapp[15417]: [NIT_IPC 0x7fa36189e700] : nitlib_get_sevlist_from_name: Got error -649 from NCPID for getting the SEV list from DN

Can someone tell me the meaning of this message?

I don't know the signification of "the SEV list from DN"

I can't find anything about the error -649.
