Nytro Flash Module Secured Lock State - Detection and Recovery
Nytro Flash module enters a locked state when data in it becomes unrecoverable. Syncro CSX controller firmware discovers the locked Nytro Flash module, unlocks it, and without any user intervention, re-enables the Flash module, which might have gone into a locked state because of various environmental factors. If the drive recovery from the locked state fails, the Nytro Flash module is moved to a failed state.
NOTE Syncro CSX controller generates an event if Nytro Flash module enters a locked state.
Syncro CSX controller moves Nytro Flash module from online state to configured-shield state.
If all of the Nytro Flash modules in a cache configuration go into a locked state, it results in data loss and cache configuration loss.
