STORAGE SYSTEM, CONTROL APPARATUS, COMPUTER PRODUCT, AND CONTROL METHOD

摘要

A storage system includes a first control apparatus; at least one second control apparatus managed by the first control apparatus; and a storage unit accessed by the second control apparatus. The second control apparatus determines based on detection of an error of an input/output process for storage in the storage unit whether the storage is in a blocking state, executes a resumption process of the input/output process when the storage is in the blocking state, judges whether an error occurrence frequency of the input/output process is at least a predetermined value, when the storage is not in the blocking state, and transmits to the first control apparatus, a blocking process request for the storage, when the error occurrence frequency is at least the predetermined value. The first control apparatus executes a blocking process and an error process of the storage, based on reception of the blocking process request.

主权项

1. A storage system comprising:
a first control apparatus; at least one second control apparatus that is managed by the first control apparatus; and a storage unit that can be accessed by the second control apparatuses, wherein each of the second control apparatuses includes a second processor that is configured to:
determine based on detection of an error of an input/output process for storage in the storage unit whether the storage is in a blocking state,execute a resumption process of the input/output process based on a determination of the storage being in the blocking state,judge whether an error occurrence frequency of the input/output process for the storage is at least a predetermined value, based on a determination of the storage not being in the blocking state, andtransmit to the first control apparatus, a blocking process request for the storage, based on a judgment that the error occurrence frequency is at least the predetermined value, and the first control apparatus includes a first processor that is configured to:
execute a blocking process of the storage, based on reception of the blocking process request, andexecute an error process of the storage, based on reception of the blocking process request.
