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 needs to be powered down 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 has been power cycled.
What happens if a chassis with a single CMC is downgraded with firmware prior to 1.10?
• The FlexAddress feature and configuration is removed from the chassis.
• The feature card used to activate the feature on this chassis is unchanged, and remains bound to the chassis. When this
chassis’s CMC firmware is subsequently upgraded to 1.10 or later, the FlexAddress feature is reactivated by reinserting the
original feature card (if necessary), resetting CMC (if feature card was inserted after firmware upgrade was completed), and
reconfiguring the feature.
What happens if a CMC unit is replaced with one that has firmware prior to 1.10 in a chassis with redundant CMCs?
In a chassis with redundant CMCs, if a CMC unit is replaced with one that has firmware prior to 1.10, the following procedure must
be used to ensure the current FlexAddress feature and configuration is NOT removed:
• Ensure the active CMC firmware is always version 1.10 or later.
• Remove the standby CMC and insert the new CMC in its place.
• From the Active CMC, upgrade the standby CMC firmware to 1.10 or later.
NOTE: If the standby CMC firmware is not updated to 1.10 or later and a failover occurs, the FlexAddress feature is not
configured. The feature must be reactivated and reconfigured again.
How can a SD card be recovered if the SD card was not in the chassis when the deactivation command was executed 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 the 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 FlexAddress, again.
The SD card is properly installed and all the firmware or software updates are installed. The FlexAddress is active, but the
server deployment screen does not display the options to deploy it? What is wrong?
This is a browser caching issue. Shut down 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 the chassis before issuing 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 re-activated, and the slot or fabric flexaddress configuration changes can resume.
iKVM
The message "User has been disabled by CMC control" appears on the monitor connected to the front panel. Why?
The front panel connection has been disabled by CMC. Enable the front panel using either the CMC Web interface or RACADM.
To enable the front panel using the CMC Web interface, go toiKVM → Setup tab, select the Front Panel USB/Video Enabled
option, and click Apply to save the setting.
To enable the front panel using RACADM, open a serial/Telnet/SSH text console to CMC, log in, and type:
