Severity: 3-Major


-- 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.


The 'tmsh show cm failover-status' command indicates an error.


-- Two or more devices in a sync-failover device-group. -- The management IP address is changed on one of the devices. The error appears under either of these conditions: -- The 'tmsh show cm failover-status' is run on a peer of the device that underwent the management IP address change. -- The sod_tg_conn_stat or sod_tg_msg_stat tmstat tables are inspected using the tmctl command.


You can work around this issue by running the following command on the peers of the device which underwent a management IP address change: tmsh restart sys service sod
