Deactivating FlexAddress
The FlexAddress or feature can be deactivated and the SD card returned to a pre-installation state using a RACADM command.
There is no deactivation function within the Web interface. Deactivation returns the SD card to its original state where it
can be installed and activated on a different chassis. The term FlexAddress, in this context, implies both FlexAddress and
FlexAddressPlus.
NOTE: The SD card must be physically installed in CMC, and the chassis must be powered-down before executing the
deactivation command.
If you execute the deactivation command with no card installed, or with a card from a different chassis installed, the feature is
deactivated and no change is made to the card.
To deactivate the FlexAddress feature and restore the SD card:
racadm feature -d -c flexaddress
The command returns the following status message if it is successfully deactivated:
feature FlexAddress is deactivated on the chassis successfully.
If the chassis is not powered-down prior to execution, the command fails with the following error message:
ERROR: Unable to deactivate the feature because the chassis is powered ON
For further information on the command, see the feature command section of the Chassis Management Controller for Dell
PowerEdge M1000e RACADM Command Line Reference Guide.
Configuring FlexAddress
FlexAddress is an optional upgrade that allows server modules to replace the factory-assigned WWN/MAC ID with a
WWN/MAC ID provided by the chassis.
NOTE: In this section, the term FlexAddress also indicates FlexAddress Plus.
Purchase and install the FlexAddress upgrade to configure the FlexAddress. If the upgrade is not purchased and installed, the
following text is displayed on the Web interface:
Optional feature not installed. See the Dell Chassis Management Controller Users Guide
for information on the chassis-based WWN and MAC address administration feature. To
purchase this feature, please contact Dell at www.dell.com.
If you purchase FlexAddress with your chassis, it is installed and active when you power up your system. If you purchase
FlexAddress separately, you must install the SD feature card using the instructions in the Chassis Management Controller
(CMC) Secure Digital (SD) Card Technical Specification document at dell.com/support/manuals.
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
then 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.
Selected slots have FlexAddress enabled for all fabrics that are enabled. For example, it is not possible to enable Fabric-A and B,
and have Slot 1 be FlexAddress enabled on Fabric-A but not on Fabric-B.
NOTE: Make sure that the Blade Servers are powered off before changing the fabric level (A, B, C, or DRAC) flex address.
