Additional FlexAddress Configuration for Linux
When changing from a server-assigned MAC ID to chassis-assigned MAC ID
on Linux-based operating systems, additional configuration steps may be
required:
• SLES 9 and SLES 10: Users may need to run YAST (Yet another Setup
Tool) on their Linux system to configure their network devices and then
restart the network services.
•Red Hat
®
Enterprise Linux
®
4(RHEL) and RHEL 5: Users will need to
run Kudzu, a utility to detect and configure new/changed hardware on the
system. Kudzu will present the user with The Hardware Discovery Menu, it
will detect the MAC address change as hardware was removed and new
hardware added.
Wake-On-LAN with FlexAddress
When the FlexAddress feature is deployed for the first time on a given server
module, it requires a power-down and power-up sequence for FlexAddress to
take effect. FlexAddress on Ethernet devices is programmed by the server
module BIOS. For the server module BIOS to program the address, it needs
to be operational which requires the server module to be powered up. When
the power-down and power-up sequences complete, the chassis-assigned
MAC IDs are available for Wake-On-LAN (WOL) function.
