Maintaining and Managing the Storage Configurations : 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.

NOTE  From MegaRAID Storage Manager window

Nytro Flash module firmware version 1.7 and later do not support the Right-click > Nytro Flash Module > Make Drive Offline option from the MegaRAID Storage Manager window. If you find the Nytro Flash module in an offline state, make it online by using the Right-click > Nytro Flash Module > Make Drive Offline option from the MegaRAID Storage Manager window.

NOTE  By using the StorCLI utility

Nytro Flash module firmware version 1.7 and later do not support the Nytro Flash module Make Drive Offline option. The operations performed on the Nytro Flash module Make Drive Offline option fail. If you find the Nytro Flash module offline, make it online by using the storcli /cx/ex/sx set online command.
