Managing Serviceguard 12th Edition, March 2006

Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4172
When a package starts up, the Package Switching flag
is set to match the AUTO_RUN setting, but this flag can
be changed temporarily with the cmmodpkg command
while the package is running.
Default is AUTO_RUN YES. Check the box to enable
auto-run in Serviceguard Manager; enter AUTO_RUN
YES or NO in the ASCII file.
Local LAN failover Enter Enabled or Disabled. In the event of a
failure, this permits Serviceguard to switch LANs
locally, that is, transfer the package IP address to a
standby LAN card. The default is Enabled. In the
ASCII package configuration file, this parameter is
called LOCAL_LAN_FAILOVER_ALLOWED, and possible
values are YES and NO.
Default is checked in Serviceguard Manager, or YES in
the ASCII file.
Node fail fast In the event of the failure of the control script itself, or
the failure of a subnet, or the report of an EMS (Event
Monitoring Service) monitor event showing that a
resource is down, if this parameter is set to Enabled,
Serviceguard will issue a TOC on the node where the
control script fails. In the ASCII package configuration
file, this parameter is called
NODE_FAIL_FAST_ENABLED, and possible values are YES
and NO.
The default is Disabled, not checked in Serviceguard
Manager, or NO in the ASCII file.
If NODE_FAIL_FAST_ENABLED is set to YES, the node
where the package is running will be halted if one of
the following failures occurs:
• A package subnet fails and no backup network is
available
• An EMS resource fails
• The halt script does not exist
• Serviceguard is unable to execute the halt script
• The halt script or the run script times out
