Error Recovery And Control In A Mass Storage System
US Patent:
4053752, Oct 11, 1977
Filed:
Sep 15, 1975
Appl. No.:
5/613592
Inventors:
Patrick Fred DeJohn - Dallas TX

Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G11C 2900, G06F 1104
US Classification:
2353021
Abstract:
A virtually addressed multilevel mass storage system (MSS) has error recovery and definition procedures and apparatus for controlling and enabling recovery from error conditions in an upper storage level. A plurality of possible error conditions in an upper level gives rise to errors in destaging data signals to a lower level, plus possible overwriting good data with data in error. A first such error condition is a data error detected during a destage. A second such error condition is repeated upper-level equipment (not data) errors. Both errors make data integrity of the lower-level suspect. Corrective action for a plurality of errors includes coordination with a host computer, reconfiguration, destaging data in error after precautionary steps, and preserving data in error at the failing upper level unit which is used in virtual mode except for the portion yielding the error condition.
Encoded Label Having Redundant And Scrambled Indicia For Identifying A Magnetic Tape Cartridge
US Patent:
4889982, Dec 26, 1989
Filed:
Aug 19, 1987
Appl. No.:
7/087085
Inventors:
James R. Young - Westminster CO
Michael Moy - Lafayette CO
Michael Moy - Lafayette CO
Assignee:
Storage Technology Corporation - Louisville CO
International Classification:
G06K 1906, G06K 1908
US Classification:
235494
Abstract:
An encoded label for a magnetic tape cartridge includes a substrate having an obverse side and a reverse side. The reverse side is adapted to be affixed to the magnetic tape cartridge, while the obverse side has pre-printed thereon at least two redundant indicators for identifying the magnetic tape cartridge to which the label is affixed. Each of the indicators include a plurality of characters, but the characters of one such indicator are scrambled with respect to the characters of the other indicator, thereby permitting accurate identification of the magnetic tape cartridge by an optical scanner in spite of the label's having a substantial portion missing or obliterated.
