_ DEC-O-LOG for KN15-CA _ DOL, KN15-CA-F001, SCSI controller transaction error KN15-CA-F001 JUN 94 APPLICABILITY: This FCO is customer installable and it should be installed by Customer Services ONLY when demanded by the customer. This FCO is for all DEC3000/* Alpha AXP Workstations shipped beginning December 1992 until November 1, 1993, plus all DEC 3000 Model 600 and 600S systems shipped before February 16, 1994. PROBLEM & SYMPTOM: There is an EXTREMELY REMOTE possibility that in a below normal temperature environment, a SCSI controller transaction error could occur. Through extensive testing below normal operating temperatures, all observed occurrences of this condition have resulted in a detected illegal command. Because this condition in THEORY could cause data corruption we have supplied a MUP which will fix this condition. SOLUTION: Installation of this MUP will provide enhanced parity protection on SCSI controller transactions by programming parity pass through instead of parity generation in the SCSI controller chip(s).
