Abstract
A fiber optic channel loop provides a transmission path between a computer platform and a multiple number of peripheral devices. When any change occurs in the number of connected peripheral devices or their operation status, then Fiber Channel loop is interrupted so to disable ongoing Input/Output operations to a targeted peripheral device. When this interruption is sensed, the Master Control Program of the platform will institute corrective measures to re-originate any interrupted I/O operations.
