Abstract:
A method for controlling a system includes receiving an indication that an operation has failed in a secondary storage device, suspending data operations sent to the secondary data storage device from a primary storage device, determining a failure policy set by a user, and initiating a first policy responsive to determining that the first policy is active, the first policy including sending a status query to the secondary storage device, determining whether a response has been received from the secondary storage device, determining whether the response indicates a failure of the secondary storage device responsive to determining that the response has been received from the secondary storage device, and continuing processing tasks on the server and data operations on the primary storage device responsive to determining that the response indicates a failure of the secondary storage device.
