Issue/Introduction

Either of the following CLI commands indicate that the CPM is offline:
CLI Command:
show cp-redundnacy

OR

UNIX Command:

cat /proc/cbs_hb_res

Resolution

To bring the  CPM out of the offline state, run the following commands on the offline CPM :

CBS# configure cp-redundancy set this_cp election

CBS# copy running-config startup-config

If there is a Primary CPM present in the chassis, the XOS version & configuration on the Primary CPM must match the configuration on the other CPM.

To ensure this, execute the following command on the Primary CPM:

CBS# configure cp-redundancy set other_cp election

After executing the previous command, reboot the offline CPM.

If the XOS version and configuration of the CPM being rebooted matches that of the Primary CPM, the CPM being rebooted comes out of offline state into standby state and starts synchronizing with primary CPM.

Execute the show cp-redundancy CLI command to check the synchronization status.
