which the node identified by the preceding
NODE_NAME entry belongs. Can be used only
in a site-aware disaster-tolerant cluster, which
requires Metrocluster (additional HP software);
see the documents listed under “Cross-Subnet
Configurations” (page 41) for more information.
If SITE is used, it must be used for each node in
the cluster (that is, all the nodes must be
associated with some defined site, though not
necessarily the same one).
If you are using SITEs, you can restrict the output
of cmviewcl (1m) to a given site by means of
the -S <sitename> option. In addition, you
can configure a site_preferred or
site_preferred_manualfailover_policy
(page 292) for a package.
NETWORK_INTERFACE The name of each LAN that will be used for
heartbeats or for user data on the node identified
by the preceding NODE_NAME. An example is
lan0. See also HEARTBEAT_IP,
STATIONARY_IP, and “About Hostname
Address Families: IPv4-Only, IPv6-Only, and
Mixed Mode” (page 139).
