ABSTRACT:
Data is promoted from a backing store (disk storage apparatus termed DASD) to a random access cache in a peripheral data storage system. When a sequential access bit is sent to the storage system, all data specified in a read command is fetched to the cache from DASD. If such prefetched data is replaced from cache and the sequential bit is on, a subsequent host access request for such data causes all related data, up to a predetermined maximum, not yet read to be promoted to cache.
