Symptoms

In a gateway failsafe high availability (HA) pair, with high availability (HA) unit monitors in different pools changes monitor status from "unchecked" to "up" post a full sync.

Impact

Incorrect status display.

Conditions

-- Gateway failsafe configured on a high availability (HA) pair (where one high availability (HA) unit monitors one particular pool and the other high availability (HA) unit another pool) -- LTM pool member(s) monitor status will be "unchecked" -- Run full sync on peer unit -- LTM pool member(s) monitor status will now become "up".

Workaround

-- Run 'tmsh load sys config' -- Run 'guishell to query MCPD for the pool member status (below example is for a pool named 'pool-gw' which is located on partition /Common/, change the syntax as necessary): # guishell -c "select POOL_NAME,STATUS_STATUSREASON from pool_member where POOL_NAME='/Common/pool-gw'"
