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 applicati on client using the LOG S ELECT
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.
