Firmware reversion trigger and control
First Claim
1. A method of recovery in a storage device having a supervisory controller and a plurality of additional controllers, the method comprising:
- detecting, at the supervisory controller, a reversion trigger, the reversion trigger identifying a set of two or more controllers of the plurality of additional controllers on the storage device; and
in response to detecting the reversion trigger, initiating, at the supervisory controller, recovery actions for each controller in the identified set of two or more controllers, including;
for each controller in the identified set of two or more controllers;
asserting a revert signal to the controller to execute a firmware reversion for the controller; and
resetting the controller subsequent to asserting the revert signal to the controller.

Abstract
The various embodiments described herein include systems, methods and/or devices used to enable firmware reversion triggering and control in a storage device. In one aspect, the method includes: (1) detecting a reversion trigger, the reversion trigger identifying a set of one or more controllers of a plurality of controllers on the storage device, and (2) in response to the reversion trigger, initiating recovery actions for each controller in the set of one or more controllers, including: for each controller in the set of one or more controllers: (a) asserting a revert signal to the controller to execute a firmware reversion for the controller, and (b) resetting the controller subsequent to asserting the revert signal to the controller.

15. A storage device, comprising:
-
an interface for operatively coupling the storage device with a host system; a supervisory controller with one or more processors and memory; and a plurality of additional controllers, the storage device configured to; detect, at the supervisory controller, a reversion trigger, the reversion trigger identifying a set of two or more controllers of the plurality of additional controllers on the storage device; and in response to detecting the reversion trigger, initiate, at the supervisory controller, recovery actions for each controller in the identified set of two or more controllers, including; for each controller in the identified set of two or more controllers; asserting a revert signal to the controller to execute a firmware reversion for the controller; and resetting the controller subsequent to asserting the revert signal to the controller. - View Dependent Claims (16, 17)

18. A non-transitory computer readable storage medium, storing one or more programs for execution by one or more processors of a storage device having a supervisory controller and a plurality of additional controllers, the one or more programs including instructions for:
-
detecting, at the supervisory controller, a reversion trigger, the reversion trigger identifying a set of two or more controllers of the plurality of additional controllers on the storage device; and in response to detecting the reversion trigger, initiating, at the supervisory controller, recovery actions for each controller in the identified set of two or more controllers, including; for each controller in the identified set of two or more controllers; asserting a revert signal to the controller to execute a firmware reversion for the controller; and resetting the controller subsequent to asserting the revert signal to the controller. - View Dependent Claims (19)

20. A method of recovery in a storage device having a supervisory controller and a plurality of additional controllers, the method comprising:
-
detecting, at the supervisory controller, a reversion trigger, the reversion trigger identifying a set of two or more controllers of the plurality of additional controllers on the storage device; and in response to detecting the reversion trigger, initiating, at the supervisory controller, recovery actions for each controller in the identified set of two or more controllers, including; for each controller in the identified set of two or more controllers; asserting a revert signal to the controller to execute a firmware reversion for the controller; performing a power fail operation for the controller, the power fail operation including; signaling a power fail condition to the controller, and transferring data held in volatile memory to non-volatile memory; and resetting the controller subsequent to asserting the revert signal to the controller and performing the power fail operation for the controller. - View Dependent Claims (21, 22)
