1. Pool member is still shown as down even after BIG-IP has connected to it. 2. If a pool has only one pool member, continuous logs are seen in /var/log/ltm, at the frequency of auto-init interval and in-band timer interval mentioning about pool member being in-active and active respectively.
Pool member marked down, even though the pool member is up
-- Auto-init is enabled to continuously try connecting the pool member -- An inband monitor is configured -- The inband monitor's retry interval is slightly less than auto-init interval
Configure the inband monitor's retry interval to be the lowest interval possible, which is 1 second.
Pool member should be marked as up by the inband monitor, when the pool member comes up and connection to it is successful.
