The Chassis Management Controller (CMC) is not monitoring the specified sensor.

Administrator action

The subsystem that monitors the health of the hardware (such as the temperature and fan speeds) might have failed. The event will clear when the CMC starts monitoring the sensor again.

If the event occurs once, you can safely ignore it.

If the event persists, gather logs, and then contact EMC Isilon Technical Support for additional troubleshooting. For instructions, see Gathering cluster logs.
