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 recongure deployment frameworks, DHCP servers, and routers for
various fabrics for identifying the new server.
Every server module is assigned unique WWN and/or MAC IDs as part of the manufacturing process. Before FlexAddress, if you had to
replace one server module with another, the WWN/MAC IDs changes and Ethernet network management tools and SAN resources had to
be recongured to identify the new server module.
FlexAddress allows CMC to assign WWN/MAC IDs to a particular slot and override the factory IDs. Hence, if the server module is replaced,
the slot-based WWN/MAC IDs remain the same. This feature eliminates the need to recongure Ethernet network management tools and
SAN resources for a new server module.
Additionally, the override action only occurs 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
IDs is used.
