The Parameter Codes supported are 1 through 30 where 30 is the maximum number of entries in the log page. 
If there are no entries, the command will return the Page Header with the Page Length field set to ZERO. 
Each  error event record contains diagnostic information for a single error encountered by the device. The parameter 
codes associated with the error-event records indicate the order in which the errors occurred. A higher parameter 
code indicates that the error event occurred later in time. 
Each parameter entry is 10 bytes long and has the following format:

described previously) or a reset occurs. The current cumulative values will be returned regardless of the page 
control field in the LOG SENSE CDB.
