摘要：
A data coherence system includes a generation number written to a data track of a logical sub-system. The generation number is compared to a corresponding generation number in a processing device when it is initialized. If the two generations numbers are the same, the generation numbers are incremented and saved. If not, cache associated with the logical sub-system residing within the processing device is erased and the generation numbers are reset.
