Notes:
1.All management modules are preconfigured with the same static IP address. You can use the management-module Web interface or command-line interface to assign a new static IP address for each BladeCenter unit. If DHCP is not used and you do not assign a new static IP address for each BladeCenter unit before attempting to communicate with the IBM Director software, only one BladeCenter unit at a time can be added to the network for discovery. Adding multiple units to the network without a unique IP address assignment for each BladeCenter unit results in IP address conflicts.
2.For I/O-module communication with the IBM Director server through the management-module external Ethernet port, the I/O module internal network interface and the management-module internal and external interfaces must be on the same subnet.
Configuring I/O modules
You must install and configure at least one external (in-band) port on an Ethernet switch module in I/O-module bay 1 to communicate with the Ethernet controllers that are integrated in each blade server. See the BladeCenter Management Module User’s Guide and the BladeCenter Management Module Command-Line Interface Reference Guide for information about configuring external ports on I/O modules. For I/O-device settings, see the documentation that comes with your I/O device. See “I/O (switch) modules” on page 34 for information about the location and purpose of each I/O module.
Notes:
1.If a pass-thru module is installed in I/O-module bay 1, you must configure the network switch that the pass-thru module is connected to; see the documentation that comes with the network switch.
2.You can set up Ethernet failover by installing an Ethernet switch module in I/O-module bay 2.
Configuring blade servers
To achieve communication redundancy on a blade server, you must configure the Ethernet controllers on the blade servers for failover. When failover occurs on a blade server, the secondary Ethernet controller takes over network communications, using the I/O module that is associated with that controller. Install a pair of Ethernet switches in I/O-module bays 1 and 2; then, configure them and your network infrastructure so that they can direct traffic to the same destinations. You can also install a pass-thru module that is connected to an external Ethernet switch in either or both of these I/O-module bays. See the documentation that comes with your blade server and operating system for instructions.
Using IBM Director
The IBM Director program is a system-management product that comes with the BladeCenter unit. Through the remote connection on the management module, you can use the IBM Director software at the IBM Director console to configure the BladeCenter unit, modify the configuration, and set up more advanced features.
Notes:
1.Some tasks, such as software distribution, require an in-band connection from the Director server through a campus (public) LAN to an I/O module port.
2.To manage BladeCenter redundant management modules with the IBM Director software, IBM Director version 4.1.01 or greater is required.
