4.2 Log Parameters

The Accumulated start-stop cycles is a parameter provided by the device sever. The accumulated start-stop cycles parameter shall not be savable by the application client using the LOG SELECT command. The parameter value is a 4-byte binary number. The value indicates how many start-stop cycles the device has detected since its date of manufacture. For rotating magnetic storage device, a single start-stop cycle is defined as an operational cycle that begins with the disk spindle at rest, continues while the disk accelerates to its normal operational rotational rate, continues during the entire period the disk is rotating, continues as the disk decelerates toward a resting state, and ends when the disk is no longer rotating. The count is incremented by one for each complete start-stop cycle. No comparison with the value of parameter 0003h shall be performed by the device server.
