224 Using FlexAddress
6 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 will return this message:
No features active on the chassis. ERROR: read
only file system
7
What will happen if there isn’t an SD card in the active CMC module?
The
$racadm featurecard -s command will return this message:
No feature card inserted.
8
What will happen to my FlexAddress feature if the server BIOS is updated
from version 1.
xx to version 2. xx ?
The server module will need to be powered down before it can be used
with FlexAddress. After the server BIOS update is complete, the server
module will not get chassis-assigned addresses until the server has been
power cycled.
9 What will happen if a chassis with a single CMC is downgraded with
firmware prior to 1.10?
• The FlexAddress feature and configuration will be 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 the CMC (if feature card was inserted
after firmware upgrade was completed), and reconfiguring the feature.
