> Serviceable Flash Module Secured Lock State – Detection and Recovery

> Serviceable Flash module enters a locked state when data in it becomes unrecoverable. Nytro controller firmware discovers the locked Serviceable Flash module, unlocks it, performs secure erase of the user data on the drive as part of lock recovery, and without any user intervention, re-enables the Serviceable Flash module that might have gone into a locked state because of various environmental factors. If the drive recovery from the locked state fails, the Serviceable Flash module is moved to a failed state.

> NOTE Nytro controller generates an event if Serviceable Flash module enters a locked state.

> Nytro controller moves Serviceable Flash module from online state to configured-shield state.

> If all of the Serviceable Flash modules in a cache configuration go into a locked state, it results in data loss and cache configuration loss.
