IBM 8677 manual Configuring Wake on LAN in the BladeCenter unit

Page 55

For the IBM Director software to discover the BladeCenter unit, your network must initially provide connectivity from the IBM Director server to the BladeCenter 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 your BladeCenter 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 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 onto 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 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.

Configuring Wake on LAN in the BladeCenter unit

Complete the following steps to configure the Wake on LAN feature in the

BladeCenter unit:

1.Write down the MAC addresses of the integrated Ethernet controllers of each blade server. This information can be found using the Configuration/Setup Utility program for each blade server (Devices and I/O Ports → System MAC Addresses). The blade server MAC addresses can also be found on a bar code label that is on the bottom of the blade server enclosure. There might also be a loose label that comes with the blade server that has the MAC addresses printed on it. The MAC addresses are needed to configure a remote system to start the blade servers using the Wake on LAN feature: the remote system issues the Wake on LAN command (magic packet) by broadcasting it to a MAC address.

2.Make sure that the Wake on LAN feature is enabled in the BladeCenter management module (Blade Tasks → Power/Restart and Blade Tasks → Configuration in the management module Web interface).

3.Make sure that the external ports of the Ethernet switch modules or pass-thru modules in I/O-module bays 1 and 2 are enabled (I/O Tasks → Management → Advanced Management in the management module Web interface). If the external ports are not enabled, blade servers in the BladeCenter unit will not be able to communicate with the external network.

Verifying your Wake on LAN configuration

Complete the following steps to verify that the Wake on LAN feature was properly configured and is functioning:

1.Start the blade server operating system.

2.Attempt to ping the remote computer that will issue the Wake on LAN command (magic packet). This verifies network connectivity.

3.Make sure that the blade server is the current owner of the keyboard, video, and mouse (KVM).
