Configuring FlexAddress for Server-Level Slots Using RACADM
To configure the flexaddress for Server-level slots using RACADM:
racadm setflexaddr [-i <slot#> <state>] [-f <fabricName> <state>]
where, <slot#> = 1 to 16
<fabricName> = A, B, C
<state> = 0 or 1
0 is disable and 1 is enable.
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:
• SUSE Linux Enterprise Server 9 and 10 — You may need to run Yet Another Setup Tool (YAST) on the Linux system to configure 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 configure 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 Configuration
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) configuration 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 filter 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 specific 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 field. You can filter using any or all of the fields displayed.
• Advanced Mode — In this mode you can view all the fields displayed in the basic mode and all the MAC types (Server Assigned, Flex
Address, and IO Identity). You can filter using any or all of the fields displayed.
