STORAGE SYSTEM AND STORAGE DEVICE PROTECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a storage system which can be configured at a lower cost as compared with a system using a remote replication by improving the environment resistance of a storage device before or just after any occurring or coming disaster. SOLUTION: Sensors 19a to 19n monitor the environment of a storage device 11 for performing reading or writing of data to magnetic disk devices 14a to 14h via a logical drive LD according to access from a host device 12. An environment information management means 22 as the function of a disk controller 13 evaluates environment information detected by the sensors 19a to 19n, and a control means 21 performs a degeneration operation to stop the storage device 11 when receiving any external stress exceeding the operation range of the storage device 11 from the environment information management means 22.
