If the original feature card is present in the active CMC on that or any other chassis, the Web interface displays the
following error message:
This feature card was activated with a different chassis. It must be removed before
accessing the FlexAddress feature.
Current Chassis Service Tag = XXXXXXXX
Feature Card Chassis Service Tag = YYYYYYYY
The original feature card is no longer eligible for deactivation on that or any other chassis, unless Dell Service reprograms the
original chassis service tag back into a chassis, and CMC that has the original feature card is made active on that chassis.
The FlexAddress feature remains activated on the originally-bound chassis. The binding of that chassis feature is updated to
reflect the new service tag.
Is an error message displayed if two feature cards are installed in a redundant CMC system?
A feature card in the active CMC is active and installed in the chassis. The second card is ignored by CMC.
Does the SD card have a write-protection lock on it?
Yes it does. Before installing the SD card into the CMC module, verify the write protection latch is in the unlock position. The
FlexAddress feature cannot be activated if the SD card is write protected. In this situation, the $racadm feature -s command
returns this message:
No features active on the chassis. ERROR: read only file system
What happens if there is no SD card in the active CMC module?
The $racadm featurecard -s command returns this message:
No feature card inserted.
What happens to FlexAddress feature if the server BIOS is updated from version 1.xx to version 2.xx?
The server module must be turned off before it can be used with FlexAddress. After the server BIOS update is complete, the
server module does not get chassis-assigned addresses until the server is power cycled.
How can an SD card be recovered if the SD card was not in the chassis when the deactivation command was run on
the FlexAddress?
The issue is that the SD card cannot be used to install FlexAddress on another chassis, if it was not in CMC when FlexAddress
was deactivated. To recover use of the card, insert the card back into a CMC in the chassis that it is bound to, reinstall
FlexAddress, and then deactivate the FlexAddress.
The SD card is properly installed and all the firmware or software updates are installed. The FlexAddress is active,
the server deployment screen does not display the options to deploy it? What is wrong?
This is a browser caching issue. Log off from the browser and relaunch.
What happens to FlexAddress if I need to reset my chassis configuration using the RACADM command, racresetcfg?
The FlexAddress feature will still be activated and ready to use. All fabrics and slots are selected as default.
NOTE: It is highly recommended that you turn off your chassis before running the RACADM command racresetcfg.
After disabling only the FlexAddressPlus feature (leaving FlexAddress still activated), why does the racadm
setflexaddr command on the (stillactive) CMC fail?
If the CMC subsequently becomes active, with the FlexAddressPlus feature card still in the card slot, the FlexAddressPlus
feature gets reactivated, and slot or fabric flexaddress configuration changes can resume.
IOM
After a configuration change, sometimes CMC displays the IP address as 0.0.0.0.
Click the Refresh icon to see if the IP address is set correctly on the switch. If an error is made in setting the IP/mask/
gateway, the switch does not set the IP address and returns a 0.0.0.0 in all fields.
Common errors are:
Setting the out-of-band IP address to be the same as, or on the same network as, the in-band management IP address.
Entering an invalid subnet mask.
Setting the default gateway to an address that is not on a network, which is directly connected to the switch.
