Title: Error reporting system
Inventor: FUKAZAWA FUMIO
IPC: G06F11/30
Filed: 1985-03-05
Abstract: PURPOSE:To avoid a case where an OS uses wrong data by giving an answer for detection of an error before the next data part is read, reporting the sense byte of a prescribed format and a prescribed message in case the data overrun is produced at a data part and the data can be read normally through a command retrial with a channel. CONSTITUTION:An error is reported to a CH 2 in case the prescribed number of retrials are carried out and a normal reading job is impossible even after the retrials exceed its prescribed frequency. While an error signal output part 7 resets a flag 1 as long as it is kept on and also reports an error to the CH 2 at the next start in case the normal reading job is possible just with several retrials. The contents of the sense byte to be reported to the CH 2 are produced on the premise that the data check that can be corrected is produced artificially at a data part. Then an OS corrects the data recorded on an MEM 5 by the error recovery processing with use of an error pattern in the error contents and according to the reported error contents.
