Abstract:
An apparatus, system, and method are provided for controlling link status changes across multiple independent control modules. The apparatus includes a copy services module configured to control multiple link adapters, each configured to establish multiple communication links between a source and a target storage device. The adapter transmits a link status change notification to the copy services module and starts a timer upon transmitting the link status change notification. The copy services module simultaneously processes link status change notifications from a plurality of communication links. The system includes a communications network and a plurality of storage devices having the above described apparatus. The method includes controlling a plurality of link adapters configured to establish multiple communication links between storage devices, transmitting a link status change notification, starting a timer upon transmitting the link status change notification, and simultaneously processing link status change notifications from a plurality of communication links.
