Table 5.4 Error recovery processing procedures (1 of 5)
Recovery
Method
Recovery Processing Procedure
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 SCSI protocol and error recovery processing is impossible. Terminate
processing and check the system's SCSI bus operation.
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.
