5.1 Troubleshooting CMCs
The chassis management controllers (CMCs) have several status LEDs that can
provide some troubleshooting assistance. See
TABLE 5-1.
Additionally, the following commands can help troubleshooting CMCs:
■ i2ctest
■ clia shmstatus
■ clia sensordata
■ clia getfruledstate
5.2 Powering Off CMCs
So long as standby power is present, the CMCs are on. A CMC can’t be powered off,
but it can be deactivated with the clia deactivate command. Deactivating
means to stop administration from that CMC.
