Lustre 1.6 Operations Manual

Note – This script can be easily adapted to pass the group NIDs by shell variables
or command line arguments (making it good for general-purpose use).
19.4.2 LNET Self-Test Concepts
This section describes the fundamental concepts of LNET self-test.
19.4.3 LNET Self-Test Commands
The LNET self-test (lst) utility is used to issue LNET self-test commands. The lst
utility takes a number of command line arguments. The first argument is the
command name and subsequent arguments are command-specific.
19.4.3.1 Session
This section lists lst session commands.
Process Environment (LST_SESSION)
The lst utility uses the LST_SESSION environmental variable to identify the session
locally on the self-test console node. This should be a numeric value that uniquely
identifies all session processes on the node. It is convenient to set this to the process
ID of the shell both for interactive use and in shell scripts. Almost all lst commands
require LST_SESSION to be set.
