T10/1236-D Revision 20 18 July 2001A.3 LOG SENSE commandThe LOG SENSE command may be used to do two functions. One is to allow the device server to save the logparameters in a log page to nonvolatile storage. The other is to allow an application client to receive the value ofthe current log parameters for a given log page.Table A.1 lists the definitions of the LOG SENSE CDB fields.LOG SENSE CDBValuesPPCbitSPbitPCfieldTable A.1 — LOG SENSE Command CDB fieldsDescription0 - -- Indicates that the log parameter requested from the device server begin with theparameter code specified by the PARAMETER POINTER field in ascending order ofparameter codes from the specified log page.1 - -- Indicates that the device server returns a log page consisting only of the logparameters in which a log parameter value has changed since the last LOGSELECT or LOG SENSE command. The device server returns only those logparameters with a parameter code greater than or equal to the parameter codespecified by the PARAMETER POINTER field.- 0 -- Indicates that the device server performs the specified LOG SENSE commandand does not save any log parameters.- 1 -- Indicates that the device server performs the specified LOG SENSE commandand saves all log parameters identified as savable by the DS bit to a nonvolatilevendor specific location if allowed. See the table A.3 to determine the interactionbetween the SP and DS bits to see what 'allowed' means.- - 00 Indicates that the device server returns current threshold values.- - 01 Indicates that the device server returns current cumulative values.- - 10 Indicates that the device server returns default threshold values.- - 11 Indicates that the device server returns default cumulative values.220 dpANS <strong>SCSI</strong> <strong>Primary</strong> <strong>Commands</strong> - 2 (SPC-2)
