After Updating the IBM PureFlex CMM Firmware, my compute nodes showed up yellow on the chassis layout screen:

IBM PureFlex CMM Firmware Update

IBM PureFlex CMM Firmware Update

Various errors were logged in the CMM event viewer and within the FSM:

Flex System Manager (FSM) event log:

Node nodexx device Addin cards[05] VPD is not valid.Node nodexx device Storage back plane[01] VPD is not available.

CMM event log:

Node nodexx device Addin cards[05] VPD is not valid.Node nodexx device Storage back plane[01] VPD is not available.

As it turns out, this is a known issue from IBM: VPD Messages KB, CMM Firmware Update KB

The resolution appears to be to update the firmware on all of the compute notes. Which is easiest done from the FSM. So log into the FSM and click on Update Chassis Components
