8.8.5 Adaptive Routing Manager Options File
The default location of the AR Manager options file is /etc/opensm/ar_mgr.conf. To set an alter-
native location, please perform the following:
1. Add 'armgr --conf_file
<ar-mgr-options-file-name> to the event_plugin_option' option
in the file
# Options string that would be passed to the plugin(s) event_plugin_options
armgr --conf_file <ar-mgr-options-file-name>
2. Run Subnet Manager with the new options file:
opensm -F <options-file-name>'
AR Manager options file contains two types of parameters:
1. General options - Options which describe the AR Manager behavior and the AR parameters
that will be applied to all the switches in the fabric.
2. Per-switch options - Options which describe specific switch behavior.
Note the following:
• Adaptive Routing configuration file is case sensitive.
• You can specify options for nonexisting switch GUID. These options will be ignored
until a switch with a matching GUID will be added to the fabric.
• Adaptive Routing configuration file is parsed every AR Manager cycle, which in turn is
executed at every heavy sweep of the Subnet Manager
.
• If the AR Manager fails to parse the options file, default settings for all the options will
be used.
