HP XC System Software Administration Guide Version 3.0

Note
You must launch this command from the head node. Run this command only during allocated preventive
maintenance time frames because this diagnostic tool uses the adapter and the link 100 percent of the time
during the test and, as a result, has a great affect on machine performance.
The command format for qsnet2_drain_test utility is shown here:
qsnet2_drain_test [-help] [-d logdirectory]
The -help option displays the command line options.
The -d option enables you to specify a log directory. The output from the qsnet2_drain_test utility and
from individual tests is bundled in a tar file (compressed with the gzip utility) and placed in the specified
log directory; the directory/var/log/diag/quadrics/qsnet2_drain_test is used by default if the
-d option is not specified.
Note
You must manually unzip the tar file, extract the files, and examine them for errors.
