If mac address defined, DHCP server already knows this node. bmcdiscover will not send genesis kernel , but the node attribute will be replaced from discover packet if there are difference.
For the mtms-based discover, the bmcdiscover will send findme packet and looking for per-definied node with same mtm/serial. Yes, if it didn't find, that would cause bmcdiscover to think this node hasn't been discovered, the temp bmc discover will not be removed from xcat database. The discover packet should contain same info as what defined for the storage node (CPU, disksize, mtm/serial, memory....), i think you should just keep mac, mtm/serial for the storage node, it will not run into discovery process. ...................................................................

If I remove mtms and serial from the storage node definition, how would that cause bmcdiscover to ignore this node? It seems to me that in the contrary, that would cause bmcdiscover to think this node hasn't been discovered yet. But your response inspired a thought - if I do the opposite and *add* mtms, serial and MAC address to the storage node object, would that be enough to get bmcdiscover to think this node has already been discovered? Or do I need any other settings? _____________________________________________________________________ Kevin Keane | Systems Architect | University of San Diego ITS | kke...@sandiego.edu Maher Hall, 192 |5998 Alcalá Park | San Diego, CA 92110-2492 | 619.260.6859 REMEMBER!

I am looking for a way to exclude one node from being discovered (MTMS-based discovery). The background is that we have quite a few compute nodes, and one storage node. The storage node is managed separately, but is of course connected to the same networks as the compute nodes. If I blindly run bmcdiscover on the whole subnet, it will discover the storage node. The worst-case scenario is that I accidentally reformat it and lose data. So I am looking for a way to keep this node from ever even being discovered in the first place. Any ideas?
