Sense Data and Error Recovery Methods

Table 6.6 Error recovery processing procedures (3/4)

Recovery		Recovery Processing Procedure
Method
13	1)	Execute a HARD RESET sequence.
	2)	After waiting 2 seconds or longer, reissue the original command (Retry), and if
		the spindle motor's start mode is set on "Start by Command," issue the START
		instruction by the NOTIFY Primitive (ENABLE SPINUP) before retrying.
	3)	If the retry procedure 2) does not terminate normally, perform recovery
		method 1.
14	1)	The parameter is initialized at the "Save" value (if the "Save" value does not
		exist, the "Default" value), so when it is necessary to set the inherent
		parameter, issued the MODE SELECT command.
	2)	Reissue the original command (Retry).
16	1)	Issue the LOG SENSE command and read the "Current" values in the LOG
		SELECT parameters.
	2)	If the parameters' values are appropriate, reissue the original command.
	Note This error could also be caused by a UNIT ATTENTION condition being
		generated, caused by a programming error of another INIT, so when the
		value in the parameter read in ( is illegal, recovery method 2 should be
		performed, or the operations of the other INITs should be confirmed.)
17	If the PRIORITY RESERVE command issued by another INIT is proper in the
	system, perform the necessary recovery processing in the system. If not, perform
	recovery method 2.
18	1)	Issue the MODE SENSE or MODE SENSE EXTENDED command and
		confirm the values of the disk media data format related parameters (Block
		descriptor, Page 3: Format parameters, Page 4: Drive parameters).
	2)	If the parameter values are correct, issue the FORMAT UNIT command and
		initialize the entire disk media surface. (Note)
	3)	If the parameter values are not correct, issue a MODE SELECT or MODE
		SELECT EXTENDED command and reset the necessary parameters, then
		reinitialize the entire disk media surface by the FORMAT UNIT command.
		(Note)
	Note In a system where multiple INITs are connected together, an error may have
		been reported due to a MODE SELECT or MODE SELECT EXTENDED
		command, or a FORMAT UNIT command issued by another INIT, so before
		executing this recovery method, it is necessary to confirm the operations of
		the other INITs.
