Configuring Packages and Their Services
Choosing Package Modules
Chapter 6274
Relocatable IP addresses cannot be assigned to multi_node packages.
Examples are the Veritas Cluster File System (CFS) system
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 the cfsdgadm and cfsmntadm commands, not
by editing a package configuration file. See “Configuring Veritas
Multi-node Packages” on page 315.
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” on page 299.
• 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 (see page 283) and auto_run
(see page 283) must be set to yes for this type of package. All services
must have service_fail_fast_enabled (see page 290) set to
yes.
System multi-node packages are supported only for applications
supplied by HP, for example Veritas Cluster File System (CFS).
NOTE On systems that support CFS, you configure the CFS system
multi-node package by means of the cfscluster command, not by
editing a package configuration file. See “Configuring Veritas System
Multi-node Packages” on page 313.
