Storage system, storage device, and monitoring server

摘要

A monitoring server (30) includes a transmission and reception unit (301) that receives information from a first storage device (10) and a second storage device (20) by performing polling to the first storage device and the second storage device at a certain interval, and transmits the received information to the first storage device and the second storage device at next polling. The first storage device and the second storage device includes a failover processing unit (103,203) that inactivates a communication port (11a,11b,12a,12b,21a,21b,22a,22b) when the failover processing unit determines that abnormality has occurred in a communication path between the first storage device and the second storage device and determines, based on the polling from the monitoring server, that abnormality has occurred in a communication path between the storage device and the monitoring server.
