FIRST_CLUSTER_LOCK_VG,
SECOND_CLUSTER_LOCK_VG
The volume group containing the physical disk volume on
which a cluster lock is written. This parameter is used only
when you employ a lock disk for tie-breaking services in the
cluster. If you are creating two cluster locks, enter the volume
group name or names for both locks.
Use FIRST_CLUSTER_LOCK_VG for the first lock volume
group. If there is a second lock volume group, specify the
SECOND_CLUSTER_LOCK_VG on a separate line in the
configuration file.
NOTE: Lock volume groups must also be defined in
VOLUME_GROUP parameters in the cluster configuration file.
Can be changed while the cluster is running; see “What
Happens when You Change the Quorum Configuration
Online” (page 47) for important information.
QS_HOST The fully-qualified hostname or IP address of a system outside
the current cluster that is providing quorum service to the
cluster. Can be (or resolve to) either an IPv4 or an IPv6
address if HOSTNAME_ADDRESS_FAMILY is set to ANY, but
otherwise must match the setting of
HOSTNAME_ADDRESS_FAMILY. This parameter is used
only when you employ a Quorum Server for tie-breaking
services in the cluster. You can also specify an alternate
address (QS_ADDR) by which the cluster nodes can reach
the Quorum Server.
For more information, see “Using a Quorum Server”
(page 95) and “Specifying a Quorum Server” (page 180).

QS_ADDR An alternate fully-qualified hostname or IP address for the
