This topic provides information about discovering a BladeCenter® chassis. If the BladeCenter chassis is located on the same subnet as the management server, IBM Director can discover the BladeCenter automatically. If the BladeCenter chassis is located on a different subnet, you must discover the BladeCenter chassis manually.
IBM Director Server uses Service Location Protocol (SLP) to communicate out-of-band with the BladeCenter chassis. This communication occurs through the external Ethernet port on the BladeCenter management module. When the BladeCenter management module first is started, the management module attempts to acquire an IP address for the external management port using Dynamic Host Configuration Protocol (DHCP). If this attempt fails, the BladeCenter management module assigns an IP address (192.168.70.125) to the external management port.
