LTM Health Monitor Issue

There is a pool which has three members but two of them are not coming up with any of the health monitor. I tried, gateway ICMP, TC-half open, content monitoring almost everything. However, one member of the same pool is working fine. 

I would appreciate any suggestion. 

 

Thanks,

    A few questions and things to look for...

    1. What port is designated for the pool? Is the pool member's firewall allowing it?
    2. Can you ping the pool member's IP from your workstation?
    3. Compare the pool member firewall settings of the working server with the two non-working ones.
    4. Depending on the configuration, you can also try using http or tcp for monitoring options.
    5. A tcpdump could be run, but I'd verify the basic stuff first.

    I'm sure others have some ideas, but this may help.
