monitored non-heartbeat subnets here. You can
identify any number of subnets to be monitored.
IMPORTANT: In a cross-subnet configuration,
each package subnet configured on an interface
(NIC) must have a standby interface connected
to the local bridged network; see “Cross-Subnet
Configurations” (page 41).
A stationary IP address can be either an IPv4 or
an IPv6 address. For information about the IPv6
address format, see “IPv6 Address Types”
(page 433).
For information about changing the configuration
online, see “Changing the Cluster Networking
Configuration while the Cluster Is Running”
(page 331).
CLUSTER_LOCK_LUN The path on this node for the LUN used for the
cluster lock. Used only if a lock LUN is used for
tie-breaking services.
Enter the path as it appears on each node in the
cluster (the same physical device may have a
different name on each node). The path must
identify a block device.
You cannot create a dual cluster-lock
configuration using LUNs.
See “Setting Up a Lock LUN” (page 202) and
“Specifying a Lock LUN” (page 219) for more
information.
Can be changed while the cluster is running; see
“Updating the Cluster Lock LUN Configuration
Online” (page 328). See also “What Happens
when You Change the Quorum Configuration
Online” (page 66) for important information.
FIRST_CLUSTER_LOCK_PV,
SECOND_CLUSTER_LOCK_PV
The path on this node for the physical volume
within the cluster-lock Volume Group that will
have the cluster lock written on it (see the entry
for FIRST_CLUSTER_LOCK_VG and
SECOND_CLUSTER_LOCK_VG near the
beginning of this list). Used only if a lock disk is
used for tie-breaking services. Use
