Configuring Flexaddress; Configuring Flexaddress For Chassis-Level Fabric And Slots - Dell EMC PowerEdge VRTX User Manual

Current Status = redundant, active
Date/time Activated = 05 Oct 2013 - 11:50:58
Feature installed from SD-card serial number = CN0H871T1374036T00MXA00
If there are no active features on the chassis, the command returns a message:
racadm feature -s
No features active on the chassis
Dell Feature Cards may contain more than one feature. After any feature included on a Dell Feature Card has been activated on a
chassis, any other features that may be included on that Dell Feature Card cannot be activated on a different chassis. In this case,
the racadm feature -s command displays the following message for the affected features:
ERROR: One or more features on the SD card are active on another chassis
For more information about the feature and featurecard commands, see the Chassis Management Controller for PowerEdge
VRTX RACADM Command Line Reference Guide available at the support site.

Configuring FlexAddress

FlexAddress is an optional upgrade that allows server modules to replace the factory-assigned WWN/MAC address with a
WWN/MAC address provided by the chassis.
NOTE: In this section, the term FlexAddress also indicates FlexAddress Plus.
NOTE: By using the racresetcfg subcommand, you can reset the Flex Address of a CMC to its factory-default setting,
which is "disabled". The RACADM syntax is:
racadm racresetcfg -c flex

properties, see the
available at dell.com/cmcmanuals.
The server must be turned off before you begin configuration. You can enable or disable FlexAddress on a per-fabric–basis.
Additionally, you can enable or disable the feature on a per-slot–basis. After you enable the feature on a per-fabric–basis, you can
select slots to be enabled. For example, if Fabric-A is enabled, any slots that are enabled have FlexAddress enabled only on Fabric-A.
All other fabrics use the factory-assigned WWN/MAC on the server.
NOTE: FlexAddress does not take effect on a server module until the next reboot. 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 addresses are available for Wake-On-LAN (WOL)
function.

Configuring FlexAddress for Chassis-Level Fabric and Slots

At the chassis level, you can enable or disable the FlexAddress feature for fabrics and slots. FlexAddress is enabled on a per-fabric–
basis and then slots are selected for participation in the feature. Both fabrics and slots must be enabled to successfully configure
FlexAddress.
Configuring FlexAddress for Chassis-Level Fabric and Slots Using CMC Web Interface
If a server is present in the slot, turn it off before enabling the FlexAddress feature on that slot.
To enable or disable fabric and slots to use the FlexAddress feature using the CMC Web interface:
1. In the left pane, click Server Overview → Setup → FlexAddress..
2. On the Deploy FlexAddress page, in the Select Fabrics for Chassis-Assigned WWN/MACs section, select the fabric type
(Fabric-A or iDRAC) to which you want to enable FlexAddress. To disable, clear the option.
3. On the Select Slots for Chassis-Assigned WWN/MACs page, select the Enabled option for the slot to which you want to
enable FlexAddress. To disable, clear the option.
