Check the logs for any fence_ipmilan messages around this time. You can
also try to run the command manually (and maybe add "-v" for verbose
messages):

fence_ipmilan -A md5 -a 192.168.33.127 -p 12345678 -l admin -o monitor
-L admin

I don't think there's a "hostname" option for fence_ipmilan. I think you
mean "pcmk_host_list=ubuntu211", because without that, Pacemaker will
try to use st-ipmilan1 when fencing *either* node. (Of course, once this
is working, you'll want to set up a st-ipmilan2 similarly.)

I think "priv" should be "privlvl".

If these are on-board IPMI controllers, which share their power supply
with the host computer, then fencing will fail if the power fails, and
the cluster will refuse to run any services. If that's undesirable, you
may want to consider a second fencing level using intelligent power
switches or some other alternative fencing method.
