Abstract
A storage device may recover from a firmware failure that places the storage device in an undetectable state. The storage device includes a memory device to store recovery firmware. A storage device controller includes a failure detector module that may identify the firmware failure when a periodic signal is not received by the failure detector module from a firmware thread, when the failure detector module determines that an initialization counter value is greater than an initialization threshold, or when the failure detector module receives a notification of a predefined number of power cycle events occurring with a given time frame. Upon identifying the firmware failure, the failure detector module updates a boot address. A recovery module May obtain recovery firmware from the memory device, based on the boot address, to recover the storage device in a recovery mode, and perform phased recovery actions to restart the storage device.
