A node name can be up to 39 characters (bytes) long;
more details in Chapter 6 under node_name (see page
202).
auto_run If auto_run is set to yes, Serviceguard will
automatically start the package on an eligible node if
one is available, and will automatically fail the package
over to another node if it fails. If auto_run is set to no,
Serviceguard will not automatically start the package
up; you must do it manually using the cmrunpkg
command.
When a package starts up, the Package Switching flag
is set to match the auto_run setting, but you can
change this flag while the package is running by means
of the cmmodpkg command.
Default is yes.
node_fail_fast_enabled
If this parameter is set to yes and one of the following
events occurs, Serviceguard will halt the system
(system reset) on the node where the control script
fails:
• A package subnet fails and no backup network is
available
• A monitored resource fails
• Serviceguard is unable to execute the halt function
• The start or halt function times out
NOTE If the package halt function fails with “exit 1”,
Serviceguard does not halt the node, but sets
no_restart for the package, which disables package
switching (auto_run), thereby preventing the package
from starting on any adoptive node.
If this occurs, check what caused the condition before
manually restarting the package on another node.
Possible values are yes and no.
