Managing Serviceguard 11th Edition, Version A.11.16, Second Printing June 2004

Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4 163
In the ASCII package configuration file, the AUTO_RUN
parameter was formerly known as
PKG_SWITCHING_ENABLED. The parameter determines
how a package may start up. If Automatic Switching is
enabled (AUTO_RUN set to YES), the package will start
up automatically on an eligible node if one is available,
and will be able to fail over automatically to another
node. If Automatic Switching is set to Disabled
(AUTO_RUN set to NO), the package will not start up
automatically when the cluster starts running, and will
not be able to fail over automatically to another node.
Default is AUTO_RUN YES in the ASCII file, which allows
a package to start up normally on an available node.
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 Manger, 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 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
Manger, or NO in the ASCII file.
