ABSTRACT:
The DASD file system copy system functions to enable the data processor to manage the data file copy function of a disk data storage subsystem in a manner that minimizes the expenditure of data processor resources. This is accomplished by the DASD file system copy system determining the source location on the data storage subsystem, the target location on the data storage subsystem and identifying the extents of both. The DASD file system copy system then transmits data to the data storage subsystem, representative of the assignment of DASD full tracks from the source location on the data storage subsystem as well as DASD full tracks from the target location on the data storage subsystem. The data processor based DASD file system copy system then uses ECAM channel programs to instruct the data storage subsystem to perform the data file copy operation using snapshot track pointer copy operations. Upon conclusion of the data file copy operation by the data storage subsystem, the DASD file system copy system updates the meta data required to complete the data file copy operation.
