Abstract
A dynamic address switching system for use in a data processing system with redundant data storage facilities. A validation routine or module assures that dynamic switching can occur between logical devices. A swapping routine exchanges information in unit control blocks for logical devices in the redundant system thereby to enable I/O requests from a host to be redirected over another channel to the other data storage facility.
