The date of manufacture shall not be saveable by the application client using the LOGSELECT command (i.e., the log parameter DS bit shall be one). The date is expressed in numeric ASCII characters(30h – 39h) in the form YYYYWW, as shown in table 139. The state of the parameter control bits for parameter0001h is specified in table 140.Table 140 — Parameter control bits for date of manufacture parameter (0001h)Bit 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 0 The parameter is in ASCII formatLP 1 The parameter is a list parameterThe accounting date specified by parameter code 0002h may be saved using a LOG SELECT command toindicate when the device was placed in service. If the parameter is not yet set or is not settable, the default valueplaced in the parameter field shall be 6 ASCII blank characters (20h). The field shall not be checked for validity bythe device server. The state of the parameter control bits for parameter 0002h is specified in table 141.Table 141 — Parameter control bits for accounting date parameter (0002h)Bit Value DescriptionDU 0 Value provided by device serverDS 0 or 1 Device server optionally supports 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 0 The parameter is in ASCII formatLP 1 The parameter is a list parameterThe specified cycle count over device lifetime (parameter code 0003h) is a parameter provided by the deviceserver. The specified cycle count over device lifetime parameter shall not be saveable by the application clientusing the LOG SELECT command (i.e., the log parameter DS bit shall be one). The parameter value is a 4-bytebinary number. The value indicates how many stop-start cycles may typically be executed over the lifetime of thedpANS <strong>SCSI</strong> <strong>Primary</strong> <strong>Commands</strong> - 2 (SPC-2) 185
