Director software can automatically discover the BladeCenter T unit (out-of-band,
using the Ethernet port on the management module) and create a managed object
for the unit.
For the IBM Director software to discover the BladeCenter T unit, your network
must initially provide connectivity from the IBM Director server to the BladeCenter T
management-module Ethernet port. To establish connectivity, the management
module attempts to use DHCP to acquire its initial IP address for the Ethernet port.
If the DHCP request fails, the management module uses a static IP address.
Therefore, the DHCP server (if used) must be on the management LAN for the
BladeCenter T unit.
Notes:
1. All management modules are preconfigured with the same static IP address.
You can use the management-module Web interface to assign a new static IP
address for each BladeCenter T unit. If DHCP is not used and you do not
assign a new static IP address for each BladeCenter T unit before attempting to
communicate with the IBM Director software, only one BladeCenter T unit at a
time can be added onto the network for discovery. Adding multiple units to the
network without a unique IP address assignment for each BladeCenter T unit
results in IP address conflicts.
2. For switch communication with the IBM Director server through the
management-module external Ethernet port, the switch-module internal network
interface and the management-module internal and external interfaces must be
on the same subnet.
