    I have a question about FDR(Failure Detection Rate) in HACMP V5.4.1

    Our Customer had a performance issue, so all of network's heartbeat didn't sent

    I was check nim_topsvcs.en3.xxx.cluster file in /var/ha/log/

    as you can see above log...

    Missed HBs value was change 10 to 30.

    I'm wonder how can changed FDR value autometically

    Please give your comment.

    Thanks and Regards
