Sense Data and Error Recovery Methods

Table 6.6 Error recovery processing procedures (1/4)

Recovery		Recovery Processing Procedure
Method
0	It is not necessary to perform the error recovery processing. Continue processing.
1	Error recovery processing is impossible. Terminate processing.
2	This is a programming error and error recovery processing is impossible.
	Terminate processing and correct the error in the system (INIT) programming.
3	This is an error in the SAS I/F and error recovery processing is impossible.
	Terminate processing and check the system's SAS connection.
4	1)	Reissue the original command (Retry).
	2)	If the command is terminated with the same error when retried, perform
		recovery method 3 or 1.
	3)	If the command is terminated with a different error when retried, execute the
		recovery processing procedure for that error.
5	1)	After waiting about 1 second, reissue the original command (Retry).
	2)	If it doesn't recover after 10 retries, perform recovery method 1.
6	1)	Reissue the original command (Retry).
	2)	If it doesn't recover after 10 retries, perform recovery method 3.
7	1)	Reissue the original command (Retry).
	2)	If it doesn't recover after 10 retries, perform recovery method 1.
8	1)	If the DTE flag in the MODE SELECT parameter is "0," perform recovery
		method 0.
	2)	If the DTE flag in the MODE SELECT parameter is "1," execute one of the
		following according to the content indicated by the sense data.
		− If the "Valid" bit is "1," and if the address of the final data block in the
		data block group in the area specified in the command is indicated in the
		information field, perform recovery method 0.
		− If the "Valid" bit is "0," or even if the "Valid" bit is "1," but the address of
		a data block which is not that of the final data group in the area specified
		in the command is indicated in the information field, reissue the original
		command.
	3)	If this error (Other than a positioning error [15-xx]) occurs repeatedly in the
		same data block, implement alternate block allocation processing (shown in
		Section 6.4).
