# == Class: tripleo::profile::pacemaker::neutron::plugins::ml2::ovn
#
# Neutron ML2 driver Pacemaker HA profile for tripleo
#
# === Parameters
#
# [*pacemaker_master*]
# (Optional) The hostname of the pacemaker master
# Defaults to hiera('ovn_dbs_short_bootstrap_node_name')
#
# [*step*]
# (Optional) The current step in deployment. See tripleo-heat-templates
# for more details.
# Defaults to hiera('step')
#
# [*pcs_tries*]
# (Optional) The number of times pcs commands should be retried.
# Defaults to hiera('pcs_tries', 20)
#
# [*ovn_dbs_vip*]
# (Optional) The vip to be used for OVN DB servers. It is expected that
# the vip resource to be created before calling this class.
# Defaults to hiera('ovn_dbs_vip')
