storage rrt

The storage rrt command runs the Random Read Test (rrt) on a single device (if specified), or on all storage devices. The command runs the test for the time specified by the -time flag duration. The test reads block-size blocks randomly from the device. The default is to run the test once for the total number of blocks on the device.
