Options are required, optional, or none. If you require a parameter, specify it and include an equal sign. If a parameter is optional, enclose it with square brackets to show that it is optional, but do not type the brackets at the CLI. For example, --fan is optional and enter it as --fan=1 or --fan=all, and so forth. Parameters with angle brackets are required but have multiple options for the input. Do not type the angle brackets or the vertical line character in the CLI. Only use one option per command; for example, --fan=1 or --fan=all. ● test-Runs through the speeds for the fan, from highest to lowest, and checks that the fan can run at the speeds of the test. If a single fan is listed on the CLI, that fan is tested. If you use the all option, all fans are tested. The number in the parentheses during the test is the speed the system tries to reach during the test. If a fan cannot reach the desired speed within an acceptable range after 10 checks, the fan fails for that speed and the system moves on to the next fan. ● get-Gets the speed of the fan and returns it in the rate process module (RPM). ● set-Sets the speed of the fan in the RPM. NOTE: Commonly, fan speeds are in two registers and must be written in a specific order. The write command cannot change the fan speeds; use the set command.
