Hello,
Can you run a identification of one server and post the log ? Are the servers Windows servers? Or do you have ESX or Linux like OS? What type of hareware do you have ? Gen 6,7,8 or 9 ? For windows server you can use either SNMP or WBEM not both. Traps do not mean that you can read the server. Is the discovered server idientified as a Proliant.?
