Abstract
Disclosed is a method of detecting a product data error in a storage system. First and second vital product data (VPD) EEPROMs are read. Indicators of whether wither or both reads failed are received. Based on these indicators, the contents of the VPD EEPROMs may be compared. Based on a result of the comparing indicating a match, an arbitrary one of the VPD EEPROMS is used. Based on an indicator indicating an error with the first VPD EEPROM, the second VPD EEPROM is used.
