Iom - Dell EMC PowerEdge VRTX User Manual

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.
