0002201E : Standby Chassis Management Module communication is offline.

Standby Chassis Management Module communication is offline.

The primary Chassis Management Module (CMM) cannot communicate with the standby CMM. Logs and setting changes will not be mirrored to the standby CMM.

The problem might correct itself within approximately 2 minutes. If it does not correct itself, complete the following steps until the problem is solved:

  1. Perform a service-level reset of the standby CMM, to restart the standby CMM. If the problem has not corrected itself, this event will appear again in the log within approximately 5 minutes.
  2. Save the configuration from the primary CMM to a file, and restart the primary CMM. This will probably cause a failover to the standby CMM, and the standby CMM will become the primary CMM. If this event does not appear again in the log within approximately 5 minutes, the problem is now corrected. If the CMM configuration was changed while the primary CMM was unable to communicate with the standby CMM, apply the saved configuration to the current primary CMM.
  3. Replace the current standby CMM. If this event does not appear again in the log after approximately 5 minutes, the problem is now corrected. To prevent failovers that result from minor problems that are related to configuration differences between the CMMs that are not related to CMM hardware failures, consider temporarily removing the standby CMM until you can replace it. If the configurations on the primary CMM and standby CMM are the same, you can disregard this event until you are able to replace the CMM. After you replace the standby CMM, if the problem was in the standby CMM, the new standby CMM will automatically synchronize the firmware and configuration data with the primary CMM. (Older log entries will not be synchronized, but new log entries will start being synchronized.)
  4. Save the configuration from the current primary CMM to a file (the same configuration that you saved in step 2), and replace the current primary CMM. The current standby CMM automatically becomes the primary CMM. If necessary, apply the saved configuration to what is now the primary CMM.
