I would recommend configuring in an offline CIB then pushing it to production
as a whole. Eg.:

  # get current CIB
  pcs cluster cib cluster1.xml

  # edit offline CIB
  pcs -f cluster1.xml resource create Internal-IPv4 ocf:heartbeat:IPaddr2 \
    ip= nic=eth0 cidr_netmask=24 op monitor interval=30


  pcs -f cluster1.xml stonith create vmfence fence_vmware_rest \
    pcmk_host_map="gw-1:gw-1;gw-2:gw-2;gw-3:gw-3" \
    ip= ssl=1 username=corosync at vsphere.local \
    password=p4ssw0rd ssl_insecure=1

  # push offline CIB to production
  pcs cluster cib-push scope=configuration cluster1.xml
