Managing HP Serviceguard for Linux, Seventh Edition, July 2007

Configuring Packages and Their Services
Editing the Configuration File
Chapter 6 221
• script_log_file. You can specify a place for the run and halt script
to place log messages. If you do not specify a path, Serviceguard will
create a file with .log appended to each script path, and put the
messages in that file.
• log_level. See log_level on page 205.
• failover_policy. Enter configured_node if you want
Serviceguard to attempt to start the package on the first node (as
listed under node_name). Enter min_package_node if you want
Serviceguard to start the package on whichever node has the fewest
packages running at the time. Note that there are restrictions and
considerations if another package depends on this package, or this
package depends on another; see “About Package Dependencies” on
page 115.
(This parameter can be set for failover packages only.)
• failback_policy. Enter automatic if you want Serviceguard to
automatically move package to the primary node (the first node on
its list under node_name) as soon as the primary node is running
again. Enter manual if you do not want Serviceguard to move the
package to the primary node. Note that there are considerations if
another package depends on this package, or this package depends
on another; see “About Package Dependencies” on page 115.
(This parameter can be set for failover packages only.)
• If this package will depend on another package or packages, enter
values for dependency_name, dependency_condition,
dependency_location, and optionally priority.
See “About Package Dependencies” on page 115 for more
information.
NOTE Any package(s) this package depends on must already be part of the
cluster configuration by the time you validate this package (via
cmcheckconf (1m); see “Verifying and Applying the Package
Configuration” on page 225); otherwise validation will fail.
•Use monitored_subnet to specify a subnet to be monitored for this
package. If there are multiple subnets, repeat the parameter as
many times as needed, on a new line each time.
