Package Configuration Planning
Chapter 4 161
the ASCII cluster configuration file appear at the end of each entry. The
following parameters must be identified and entered on the worksheet
for each package:
Package name
The name of the package. The package name must be
unique in the cluster. It is used to start, stop, modify,
and view the package. In the ASCII package
configuration file, this parameter is PACKAGE_NAME.
In the package ASCII file, the package name can be
from 1 to 39 characters. It must not contain any of the
following illegal characters: space, slash (/),
backslash(\), and asterisk (*). All other characters are
legal.
In Serviceguard Manager, more non-alphanumeric
characters are not allowed. See the online help topic
“Configuring Packages.
PACKAGE_TYPE
The type of the package. This parameter indicates
whether the package will run on one node at a time or
on multiple nodes. Valid types are FAILOVER and
SYSTEM_MULTI_NODE. Default is FAILOVER.
The SYSTEM_MULTI_NODE type is used only to define the
VxVM-CVM-pkg package that supports shared CVM
data storage among all cluster nodes. You cannot create
a user-defined package with a type of
SYSTEM_MULTI_NODE.
Failover policy
The policy used by the package manager to select the
node on which the package should be automatically
started. In the ASCII package configuration file, this
parameter is known as FAILOVER_POLICY.
Default is CONFIGURED_NODE, which selects the next
available node in the list of node names for the
package. The order of preference is the order of the
node name entries in the package’s configuration file.
