This directory contains the shell scripts and c code used in the extended diagnostics. In order to use this stuff, you need to build it and create a directory on the test system called /usr/diags/os. Then programs in the bin subdirectory should be placed in /usr/diags/os/bin, and the scripts should be placed in /usr/diags/os/scripts. You can start the tests by using the do_ostests script. This will start the io, splock, and mem tests simultaneously. To stop the tests, use the stop_ostests script. If desired, any one of the tests can be started or stopped individually.
