T10/1236-D Revision 20 18 July 2001device without degrading the device’s operation or reliability outside the limits specified by the manufacturer of thedevice. The state of the parameter control bits for parameter 0003h is specified in table 142.Table 142 — Parameter control bits for start-stop cycle counter parameters (0003h and 0004h)The accumulated start-stop cycles (parameter code 0004h) is a parameter provided by the device server. Theaccumulated start-stop cycles parameter shall not be saveable by the application client using the LOG SELECTcommand (i.e., the log parameter DS bit shall be one). The parameter value is a 4-byte binary number. The valueindicates how many start-stop cycles the device has detected since its date of manufacture. The time at which thecount is incremented during a start-stop cycle is vendor specific. For rotating magnetic storage devices, a singlestart-stop cycle is defined as an operational cycle that begins with the disk spindle at rest, continues while the diskaccelerates 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. For deviceswithout a spindle or with multiple spindles, the definition of a single start-stop cycle is vendor specific. The count isincremented by one for each complete start-stop cycle. No comparison with the value of parameter 0003h shall beperformed by the device server. The state of the control bits for parameter 0004h is specified in table 142.8.2.10 Supported log pagesBit Value DescriptionDU 0 Value provided by device serverDS 1 Device server does not support saving of parameterTSD 0 Device server manages saving of parameterETC 0 No threshold comparison is made on this valueTMC xx Ignored when ETC is 0LBIN 1 The parameter is in binary formatLP 1 The parameter is a list parameterThe supported log page (see table 143) returns the list of log pages implemented by the target.

18 July 2001 T10/1236-D Revision 208.2.11 Temperature pageThis subclause defines the optional temperature log page (page code 0Dh). A device server that implements thetemperature page shall implement parameter 0000h. Parameter 0001h is optional and may be either omitted or setto a value indicating that the parameter is not defined.
