Table 5.3 Sense data error classification (4 of 4)
K* C* Q* Error contents L*
Recovery method
(See Table 4.4.)
B 03 xx Peripheral device write fault Need 12
11 xx Unrecovered read error
13 xx Sync byte not found for data field
14 xx Record not found
15 xx Mechanical positioning error
B 43 00 Message error Need 6
45 80 Select/Reselect failure
47 00 SCSI parity error
48 00 INITIATOR DETECTED ERROR message received
49 00 Invalid message error
An unrecoverable SCSI related error occurred in
the command execution sequence.
B 4E 00 Overlapped commands attempted None 2
Before execution of a command was completed, a
new command was issued by the same INIT.
4D nn Tagged overlapped commands
E 1D 00 Miscompare during verify operation None 24
Data failed to match in the Byte check mode of the
Verify command.
* K: Sense Key C: Sense Code
Q: Sub-sense code L: Logging Necessary? (shown in Section 5.2.3)
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.
