When NVMe drives are present in a system running prtdiag -v, the NMVe drives are not listed in output under the FRU section. Also, if a user retrieves SNMP data from Oracle ILOM the entPhysicalIsFRU entry for the NVMe drive, entries will be marked as false.
Workaround: Use the diskinfo command or the format command to see your NMVe drives.
