Important! Any hardware changes that might be required must be performed before you upgrade the system software.
Note: All Oracle FS System updates are RPM files. The single RPM file contains system software and drive firmware. Preserve the original file names and extensions of the extracted contents. Renaming the files might prevent successful staging.
Important! After upgrading the system software, update the drive firmware as soon as possible. Drive firmware updates require a maintenance window during which the system is put in standby mode. When installing the updates, select all available drive firmware updates to avoid having to schedule multiple maintenance windows. For information regarding the installation of drive firmware, refer to the Oracle Flash Storage System Software Patch ReadMe.
