Discovering a BladeCenter chassis

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.

Note: If you do not use a DHCP server to assign a temporary IP address to the BladeCenter chassis, introduce only one BladeCenter chassis onto the network at a time. IBM Director must discover and configure the chassis before another chassis is added to the LAN. Otherwise, an IP address conflict will occur.
