[ClusterLabs] How to specify which IP pcs should use?

Pacemaker 2, the current setup is

* management network with host's hostname resolving to host's
  management IP
* cluster network for Pacemaker/Corosync communication
* corosync set up with node name and IP of the cluster network

pcs status shows both nodes online, added config syncs to the other
node etc. but pcs cluster status shows one node being offline.

After a look in firewall logs it appears all of the communication is
going just fine on the cluster network but PCS tries to talk with PCSD
on port 2224 via *management* network instead of using IP set as
ring0_addr in corosync

Is "just use host's hostname regardless of config" something normal ?
Is there a separate setting to pcs about which IP it should use ?
