Abstract
A switching error detection and recovery mechanism recognizes that an I/O configuration has changed. Comparing new configuration data to previous data maintained in a CDT table structure, and detecting unequal path information, an error condition is recognized. After recognizing the error condition, recovery actions are taken to notify the operator and insure data integrity. The CDT is structured so that redundant data is eliminated, and so records may be efficiently and dynamically added and deleted.
