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.

Command Syntax

udiag storage rrt { all | <device_name> } [ -time <n> ]


Runs the test on all block storage devices.
Must be entered as HDDx, SATAx, USBx, VHDx, or NVMEx, where x represents the index of the device. The index of the device can be found by running the udiag storage info command. This command lists all devices and identifies block devices. Tests run only on block devices.
-time <n>
Specifies the maximum test time in seconds in hexadecimal. The default is 0, which indicates no time limit. The test runs to completion.

Resource Requirements



To run the test on all devices until they are complete, type:

fs0:/> udiag storage rrt all

To run the test on NVME until completion, type:

fs0:/> udiag storage rrt NVME1

To run the test on HDD03 for 1 hour, type:

fs0:/> udiag storage rrt HDD3 -time E10
