show controller fabric plane all detail

Verify the Fabric Plane state and Bundle state.

show controller switch summary

Verify the state of Exp Eth 0 and Exp Eth 1 ports. One port must be in Active (Forwarding) state, and one port must be in Standby (Blocking) state.

Verify that all the slices of line cards (if present) are in UP state.

show redundancy summary

Verify Node and NSR status is Ready.

show processes blocked location node_ID

Check for blocked processes.

Note 
The "lpts_fm" process would be the only process in blocked state.
