Forcing the Offline Nytro Flash Module into Online State

> Forcing the Offline Nytro Flash Module into Online State

> Restoring an Offline Nytro Flash module (associated to a source VD) to an Online state is not a recommended operation. This results in data mismatch between the Nytro Flash module and source VD, which leads to data corruption.

> CAUTION After you perform this operation, data corruption might occur on the VD associated with a Nytro Cache drive, regardless of the operational status of the VD. A warning message is shown in the MegaRAID Storage Manager application for this operation.

> The operation to restore an Offline Nytro Flash module to Online state is possible by using the MegaRAID Storage Manager software, and/or StorCLI utility, which is not recommended.
