Patent ID: 8036238

Claim:
An information processing system comprising: a storage device having a plurality of storage areas; an information processing device coupled to the storage device and issuing access requests; and a plurality of access paths for transmitting access requests issued from the information processing device to access the storage areas, wherein the information processing device, when a first failure is detected in a first access path selected from among the plurality of access paths for transmitting a first access request to a first storage area, is configured to perform the following processes: (a) allocating the first access request to a second access path other than the first access path where the first failure is detected, (b) from among the plurality of access paths which are provided for transmitting access requests to other storage areas, identifying a third access path sharing a part of the first access path where the first failure is detected between the information processing device and the storage device, and (c) if a second access request is issued to any one of said other storage areas, performing an access request allocation process for allocating the issued second access request to a fourth access path other than the third access path identified in the process (b).
