STORAGE SYSTEM AND CONTROL APPARATUS

摘要

A first control device includes a first storage unit holding a first error count and a first control unit that calculates the first error count, based on a status of an error detected when a storage device is accessed via a second control device, stores the calculated first error count in the first storage unit, and transmits the first error count to the second control device at predetermined timing. The second control device includes a second storage unit holding a second error count and a second control unit that calculates the second error count, based on a status of an error detected when the storage device is accessed, stores the calculated second error count in the second storage unit, and determines whether the storage device has malfunctioned, based on an aggregate value of the first error count received from the first control device and the second error count.

主权项

1. A storage system comprising:
a storage apparatus; a first control apparatus; and a second control apparatus, wherein the first control apparatus includes: a first memory configured to hold a first error count; and a first processor configured to calculate the first error count, based on a status of an error detected when the storage apparatus is accessed via the second control apparatus, store the calculated first error count in the first memory, and transmit the first error count to the second control apparatus at predetermined timing, and wherein the second control apparatus includes: a second memory configured to hold a second error count; and a second processor configured to calculate the second error count, based on a status of an error detected when the storage apparatus is accessed, store the calculated second error count in the second memory, and determine whether the storage apparatus has malfunctioned, based on an aggregate value of the first error count received from the first control apparatus and the second error count.
