* FlexAddress: If a chassis with a single CMC is downgraded with
firmware earlier than version 1.10, the FlexAddress feature and
configuration will be removed. Once the CMC firmware is upgraded
to 1.10 or later, the FlexAddress feature must be reactivated and
configured.
* FlexAddress: In a chassis with two CMCs, if you are replacing a CMC unit
with one that has firmware earlier than version 1.10, perform the
following procedure to ensure that the current FlexAddress feature and
configuration is not removed.
1. Ensure the active CMC firmware is always version 1.10 or later.
2. Remove the standby CMC and insert the new CMC in its place.
3. From the Active CMC, upgrade the standby CMC firmware to 1.10
or later.
Note: If you do not update the standby CMC firmware to 1.10 or later
and a failover occurs, the FlexAddress feature is not configured and
you will need to reactivate the feature.
* FlexAddress: Wake-On-LAN (WOL) requires BIOS to initialize MAC
values. When the FlexAddress feature is deployed for the first
time on a given modular server, it requires at least one power-up and
down sequence for FlexAddress to take effect. The reason for this is
the FlexAddress on Ethernet devices is programmed by the BIOS. The BIOS
needs to be functioning to program the address. This in turn requires
the modular server to be powered up. Once the power-up and power-down
sequence has been completed, FlexAddress is available for the
Wake-On-LAN (WOL) function. You may perform power-up and power-down sequence
on the modular server for fully deploying FlexAddress through the iDRAC
or CMC interface.
* When changing from a server-assigned MAC to a chassis-assigned MAC on
Linux operating systems, additional configuration steps may be
required.
o SLES 9 and SLES 10: You may need to run YAST (Yet another Setup
Tool) on your Linux system to configure the network devices
and then restart the network services.
o Red Hat® Enterprise Linux® version 4 and version 5: You may need
to run Kudzu, a utility to detect and configure new/changed hardware
on the system. Kudzu displays the Hardware Discovery Menu and detects
the MAC address change as hardware was removed and new hardware added.
* Prior to installing FlexAddress, you can determine the range
of MAC addresses contained on the Flexaddress feature card by
inserting the SD card into a USB “Memory Card Reader” and viewing
the file "pwwn_mac.xml". The clear text XML file on the SD card
contains an XML tag "mac_start" which is the first starting
hex MAC address that is used for this unique MAC address range.
The “mac_count” tag is the total number of MAC addresses that this
SD card allocates. The total MAC range allocated can be determined
by: "mac_start" + 0xCF (208 – 1) = mac_end.
Example:(starting_mac)00188BFFDCFA + 0xCF =(ending_mac)00188BFFDDC9
NOTE: Lock the SD card before inserting it in the USB
“Memory Card Reader” to prevent accidental modification of any of the
contents. You must unlock the SD card before inserting into the CMC.
