Abstract: Provided are a storage system including a host and a storage device and a method of operating the storage system. The method includes, when a response time of the storage device is greater than a threshold time, stopping, by the storage system, a previous mode and entering a recovery mode, when a state of a connection between the host device and the storage device is a link down state, resetting, by the storage system, the connection between the host device and the storage device, transmitting, by the host device, a recovery signal to the storage device, and performing, by the storage device, storage recovery.
