Abstract
A technique is described for assuring the global identification and management of interchangeable data storage devices in a data processing system, assuring the integrity of data storage devices after shutdowns or failures and providing these capabilities without changing any current system or application software on the host. This technique also provides high availability of data storage devices by swapping a failing data storage device with a good data storage device without host intervention.
