Managing HP Serviceguard A.11.20.10 for Linux, December 2012

the documents listed under “Cross-Subnet Configurations”
(page 27) for more information.
You can define multiple SITE_NAMEs. SITE_NAME entries
must precede any NODE_NAME entries. See also SITE.
IMPORTANT: SITE_NAME must be 39 characters or less,
and are case-sensitive. Duplicate SITE_NAME entries are
not allowed.
NODE_NAME The hostname of each system that will be a node in the
cluster.
CAUTION: Make sure that the node name is unique within
the subnets configured on the cluster nodes; under some
circumstances Serviceguard may not be able to detect a
duplicate name and unexpected problems may result.
Do not use the full domain name. For example, enter
ftsys9, not ftsys9.cup.hp.com. A cluster can contain
up to 16 nodes.
IMPORTANT: Node names must be 39 characters or less,
and are case-sensitive; for each node, the node_name in
the cluster configuration file must exactly match the
corresponding node_name in the package configuration
file (see Chapter 6: “Configuring Packages and Their
Services ” (page 163)) and these in turn must exactly match
the hostname portion of the name specified in the node’s
networking configuration. (Using the above example,
ftsys9 must appear in exactly that form in the cluster
configuration and package configuration files, and as
ftsys9.cup.hp.com in the DNS database).
The parameters immediately following NODE_NAME in this
list (NETWORK_INTERFACE, HEARTBEAT_IP,
STATIONARY_IP, CLUSTER_LOCK_LUN,
CAPACITY_NAME, and CAPACITY_VALUE) apply
specifically to the node identified by the preceding
NODE_NAME entry.
CLUSTER_LOCK_LUN The pathname of the device file to be used for the lock LUN
on each node. The pathname can contain up to 39
characters.
See “Setting up a Lock LUN” (page 137) and “Specifying a
Lock LUN” (page 149)
Can be changed while the cluster is running; see “Updating
the Cluster Lock LUN Configuration Online” (page 224). See
also “What Happens when You Change the Quorum
Configuration Online” (page 40) for important information.
SITE The name of a site (defined by SITE_NAME) to which the
node identified by the preceding NODE_NAME entry belongs.
Can be used only in a site-aware disaster recovery cluster,
which requires Metrocluster (additional HP software); see
