6.6.5.Last N Error Events List (07h)

This page is used to report information on soft and hard errors encountered by the device during normal operation. Each parameter corresponds to an encountered error and is a report of what type of error occurred and when it occurred. The format of the page is given below:

Table 6-18: Last N Error Events Page

Bit	7	6		5	4	3	2	1	0
Byte
0	Reserved					Page Code (07h)
1					Reserved

3					Parameter	Length (0Ah)
4					Parameter Value
13

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:

		Table 6-20: Error Event format
Byte Offset		Meaning
0	– 4	Result Message (see Diagnostic Clause)
	5	Unused
6	– 9	Time-stamp (number of 1 minute increments since power-on)

When the log page becomes full, no more entries will be added until the log is cleared (using one of the methods described previously) or a reset occurs. The current cumulative values will be returned regardless of the page control field in the LOG SENSE CDB.
