Abstract
An extending system in an information processing system which includes an input/output channel and operates a plurality of virtual computers. A plurality of input/output processing units are included in the input/output channel and each virtual computer issues a region ID and a channel path ID. A channel path reconfiguration array is provided having a plurality of channel path reconfiguration array blocks corresponding to region IDs. Each channel path reconfiguration array block includes a plurality of channel path reconfiguration array entries corresponding to channel path IDs and each channel path reconfiguration array entry includes an input/output processing unit number and a channel path ID. A selector is provided for selecting a channel path reconfiguration array block corresponding to the region ID issued by a virtual computer and selecting a channel path reconfiguration array entry corresponding to channel path ID issued by the virtual computer within the selected channel path reconfiguration array block. The virtual computer selects one of the input/output processing units corresponding to the input/output processing number from the selected channel path reconfiguration array entry and accesses the input/output processing circuit using the channel path ID from the selected channel path reconfiguration array entry.
