them, and then start them up on another node selected from the package’s
configuration list; see “node_name” (page 289).
To generate a package configuration file that creates a failover package, include-m
sg/failover on the cmmakepkg command line. See “Generating the Package
Configuration File” (page 311).
• Multi-node packages. These packages run simultaneously on more than one node
in the cluster. Failures of package components such as applications, services, EMS
resources, or subnets, will cause the package to be halted only on the node on
which the failure occurred.
The Veritas Cluster File System (CFS) system multi-node packages are examples
of multi-node packages; but support for multi-node packages is no longer restricted
to CVM/CFS; you can create a multi-node package for any purpose.
IMPORTANT: But if the package uses volume groups, they must be activated in
shared mode: vgchange -a s, which is available only if the SGeRAC add-on
product is installed.
NOTE: On systems that support CFS, you configure the CFS multi-node packages
by means of thecfsdgadm and cfsmntadm commands, not by editing a package
configuration file; see “Creating a Storage Infrastructure with Veritas Cluster File
System (CFS)” (page 261).
Note that relocatable IP addresses cannot be assigned to multi-node packages. See
also “Differences between Failover and Multi-Node Packages” (page 282).
To generate a package configuration file that creates a multi-node package,
include-m sg/multi_node on the cmmakepkg command line. See “Generating
the Package Configuration File” (page 311).
• System multi-node packages. These packages run simultaneously on every node
in the cluster. They cannot be started and halted on individual nodes.
Both node_fail_fast_enabled (page 290) and auto_run (page 289) must be set to yes
for this type of package. All services must have service_fail_fast_enabled (page 301)
set to yes.
System multi-node packages are supported only for applications supplied by HP,
for example Veritas Cluster File System (CFS).
