Additional FlexAddress Conguration for Linux
When changing from a server-assigned MAC ID to chassis-assigned MAC ID on Linux-based operating systems, additional
conguration steps may be required:
• SUSE Linux Enterprise Server 9 and 10 — You may need to run Yet Another Setup Tool (YAST) on the Linux system to congure
the network devices and then restart the network services.
• Red Hat Enterprise Linux 4 and Red Hat Enterprise Linux 5: Run Kudzu, a utility to detect and congure new or changed
hardware on the system. Kudzu displays The Hardware Discovery Menu; it detects the MAC address change as hardware was
removed and new hardware added.
Viewing WWN or MAC Address Information
You can view the virtual address inventory of Network Adapters for each server slot or all servers in a chassis. The virtual address
inventory includes the following:
• Fabric Conguration
NOTE:
– Fabric A displays the type of the Input/Output fabric installed. If Fabric A is enabled, unpopulated slots display chassis-
assigned MAC addresses for Fabric A.
– iDRAC management controller is not a fabric, but its FlexAddress is considered as a fabric.
– A check mark against the component indicates that the fabric is enabled for FlexAddress or FlexAddressPlus.
• Protocol that is being used on the NIC Adapter port. For example, LAN, iSCSI, FCoE, and so on.
• Fibre Channel World Wide Name (WWN) conguration and Media Access Control (MAC) addresses of a slot in the chassis.
• MAC address assignment type and the current active address type — Server assigned, FlexAddress, or I/O Identity MAC. A
black check mark indicates the active address type, either server-assigned, chassis-assigned, or remote assigned.
• Status of the NIC partitions for devices supporting partitioning.
You can view the WWN/MAC Address inventory using the Web interface or the RACADM CLI. Based on the interface, you can lter
the MAC address and know which WWN/MAC address is in use for that function or partition. If the adapter has NPAR enabled, you
can view which partitions are enabled or disabled.
Using the Web interface, you can view the WWN/MAC Addresses information for specic slots using the FlexAddress page (Click
Server Overview → Slot <x> → Setup → FlexAddress). You can view the WWN/MAC Addresses information for all the slots and
server using the WWN/MAC Summary page (Click Server Overview → Properties → WWN/MAC). From both the pages you can
view the WWN/MAC Addresses information in the basic mode or the advanced mode:
• Basic Mode — In this mode you can view Server Slot, Fabric, Protocol, WWN/MAC addresses, and Partition Status. Only Active
MAC addresses are displayed in WWN/MAC address eld. You can lter using any or all of the elds displayed.
• Advanced Mode — In this mode you can view all the elds displayed in the basic mode and all the MAC types (Server Assigned,
Flex Address, and IO Identity). You can lter using any or all of the elds displayed.
In both the Basic mode and the Advanced mode, the WWN/MAC Addresses information is displayed in a collapsed form. Click the
against a slot or click Expand/Collapse All to view the information for a specic slot or all the slots.
You can also export the WWN/MAC Addresses information for all the servers in the chassis to a local folder.
For information about the elds, see the Online Help.
Viewing Basic WWN or MAC Address Information Using Web Interface
To view WWN/MAC Address information for each server slot or all servers in a chassis, in the basic mode:
1. Click Server Overview → Properties → WWN/MAC.
The WWN/MAC Summary page displays the WWN/MAC Address Information.
