About FlexAddress
If a server is replaced, the FlexAddress for the slot remains the same for the given server slot. If the server is inserted in a new slot or
chassis, the server-assigned WWN/MAC is used unless that chassis has the FlexAddress feature enabled for the new slot. If you remove
the server, it reverts to the server-assigned address. You need not recongure deployment frameworks, DHCP servers, and routers for
various fabrics for identifying the new server.
Every server module is assigned unique WWN and/or MAC addresses as part of the manufacturing process. Without FlexAddress, if a
server had to be replaced with another server module, the WWN/MAC addresses changes and Ethernet network management tools and
SAN resources had to be recongured to identify the new server module.
FlexAddress allows CMC to assign WWN/MAC addresses to a particular slot and override the factory addresses. Hence, if the server
module is replaced, the slotbased WWN/MACaddresses remain the same. This feature eliminates the need to recongure Ethernet
network management tools and SAN resources for a new server module.
Also, the override action occurs only when a server module is inserted in a FlexAddress enabled chassis; no permanent changes are made
to the server module. If a server module is moved to a chassis that does not support FlexAddress, the factory-assigned WWN/MAC
addresses are used.
CMC VRTX chassis is shipped with the SD card, which supports FlexAddress, FlexAddress Plus, and Extended Storage features. If the
VRTX chassis is shipped with an optional second CMC, the second CMC has an SD card that supports only Extended Storage.
NOTE
:
• Data contained on the SD card is encrypted and may not be duplicated or altered in any manner, because it may inhibit system
function and cause the system to not function properly.
• The use of an SD card is limited to one chassis only. You cannot use the same SD card on another chassis.
The FlexAddress feature card contains a range of MAC addresses. Before installing FlexAddress, you can determine the range of MAC
addresses contained on a FlexAddress feature card by inserting the SD card into a USB Memory Card Reader and viewing the
pwwn_mac.xml le. This clear text XML le on the SD card contains an XML tag mac_start that is the rst starting hex MAC address that
