# and QS_TIMEOUT_EXTENSION parameters to define a quorum server.
# The QS_HOST is the host name or IP address of the system
# that is running the quorum server process. The
# QS_POLLING_INTERVAL (microseconds) is the interval at which
# Serviceguard checks to make sure the quorum server is running.
# The optional QS_TIMEOUT_EXTENSION (microseconds) is used to increase
# the time interval after which the quorum server is marked DOWN.
#
# The default quorum server timeout is calculated from the
# Serviceguard cluster parameters, including NODE_TIMEOUT and
# HEARTBEAT_INTERVAL. If you are experiencing quorum server
# timeouts, you can adjust these parameters, or you can include
# the QS_TIMEOUT_EXTENSION parameter.
#
# The value of QS_TIMEOUT_EXTENSION will directly effect the amount
# of time it takes for cluster reformation in the event of failure.
# For example, if QS_TIMEOUT_EXTENSION is set to 10 seconds, the cluster
# reformation will take 10 seconds longer than if the QS_TIMEOUT_EXTENSION
# was set to 0. This delay applies even if there is no delay in
# contacting the Quorum Server. The recommended value for
# QS_TIMEOUT_EXTENSION is 0, which is used as the default
# and the maximum supported value is 30000000 (5 minutes).
#
# For example, to configure a quorum server running on node
# “qshost” with 120 seconds for the QS_POLLING_INTERVAL and to
# add 2 seconds to the system assigned value for the quorum server
# timeout, enter:
#
# QS_HOST qshost
# QS_POLLING_INTERVAL 120000000
# QS_TIMEOUT_EXTENSION 2000000
# Definition of nodes in the cluster.
# Repeat node definitions as necessary for additional nodes.
# NODE_NAME is the specified nodename in the cluster.
# It must match the hostname and both cannot contain full domain name.
# Each NETWORK_INTERFACE, if configured with IPv4 address,
# must have ONLY one IPv4 address entry with it which could
# be either HEARTBEAT_IP or STATIONARY_IP.
# Each NETWORK_INTERFACE, if configured with IPv6 address(es)
# can have multiple IPv6 address entries(up to a maximum of 2,
# only one IPv6 address entry belonging to site-local scope
# and only one belonging to global scope) which must be all
# STATIONARY_IP. They cannot be HEARTBEAT_IP.
