Got another HA question here. For HA, if I’m using the layer 2 VIP method and I have one master and two slaves, the configurations are as below:
ha token cisco
ha interval 4
ha failure-limit 10
ha vip address 10.74.205.83
ha vip broadcast-address 10.74.205.127
ha member nso_m
ha member nso_s1
ha member nso_s2
The question is about when I deactivate the master, slave 1 will become master and slave 2 (nso_s2) will become “none”. Is it normal that slave 2 will never be the slave under the new master even if I want to do it manually (like changing the HA configurations)?
Re: A question about HA with 1 master and 2 slaves
tailf-hcc does as little as possible automagically, by design. Is the master node goes down, the fail over master will become master, and that is it (alarms are generated etc ofc, screaming for manual intervention).
If you want s2 to become slave to the new master manual steps must be taken. There is an action for it, so no need to change configuration. I suggest you take look at the deployment guide, "section 5.1.6 - HA Disaster Recovery".
