Maintaining and Managing the Storage Configurations : Upgrading the Nytro MegaRAID Firmware and Nytro Flash Module Firmware

Upgrading the Nytro MegaRAID Firmware and Nytro Flash Module Firmware

Updating firmware on the Nytro MegaRAID controller involves the following procedures:

*

Updating the Nytro controller firmware (this is usually a .rom file).

*

Updating the Nytro Flash modules firmware (this is usually a.vic file). There are two Nytro Flash modules on each Nytro MegaRAID controller.

NOTE  After upgrading the controller cache, the controller cache would be in the Write Through mode (that is, write caching disabled) until the system is restarted.

CAUTION  Do not attempt to downgrade from Nytro MegaRAID controller firmware 1.6 (3.300.xx) to Nytro MegaRAID controller firmware 1.5 or later (3.200.xx). Downgrading the controller firmware results in a non-functioning card, and might cause loss of data.
