If we physically replace a node we remove its MAC address from xCAT and when we turn it on it boots into a discovery image, gets named based on its switch port (via a system you define to it), programs the BMC/IMM appropriately and then lights up its attention light. When we brought up our new Intel system recently we just plugged it in, turned it on and waited for all the little blue lights to come on to say it was appropriately configured. :-) We can then use rpower to reboot it and it will come up in the appropriate image. > to me, a sensible cluster is nfs-root based, so there is hardly > ever any mass-configuration to do. With xCAT our diskfull nodes are not mass configured either, everything is done by node groups which have associated "osimage" definitions. We have node groups for login nodes, compute nodes, GPFS NSD servers, TSM HSM nodes, TSM backup nodes, BG/Q service nodes, etc.. So we can have a library of osimage definitions and switch groups between them.
