Symptoms
-- The 'tmsh show cm failover-status' command shows a status of 'Error' when the command is run on a peer of a device that underwent a management IP address change.
-- Should the sod_tg_conn_stat or sod_tg_msg_stat tmstat tables be inspected using the tmctl command, the tables show stale information in the entry_key column.
Note: Additionally, in certain cases, it is possible for failover functionality to be broken after the management IP address change, meaning devices remain stuck in an improper Active/Active or Standby/Standby state. This further aspect of the issue is tracked under ID999125. This ID tracks only the cosmetic defect.
