  • Patent number: 5634028
    Abstract: A computer-implemented method for translating from one DASD address to another DASD address initially stores a plurality of translation tables, one translation table for each first DASD coupled to a first processor. Each translation table includes at least a first data value for each cylinder in a first DASD which indicates whether or not the cylinder contains a start-of-extent address. If yes, the translation table has a corresponding translation entry which includes a first portion and a second portion. The first portion includes at least the start-of-extent address in the cylinder and a length of the extent of addresses associated with the start-of-extent address. The second portion includes a start-of-extent address for an address span in a second DASD that corresponds to the first portion.

  • Patent number: 5592618
    Abstract: A data copy validation technique compares primary data to a copy of that data by generating check codes of the data to be validated at both primary and secondary sites in a continuously running remote data shadowing system. The validation session runs concurrently with the data shadowing so as not to disrupt the data shadowing. Each data validation session is assigned a copy start time, for example, a time preceding a time of a consistency group, for defining when the check code for data at the primary should be compared to a check code of the data at the secondary. The check code of the data at the secondary site is taken at a time that is the equivalent logical point-in-time of that data at the primary site even though the respective data contents may be different in real time.
