3. If you configured the new storage subsystem with at least two new drives to place the
storage subsystem into the Optimal state for updating the controller firmware, power off
the new storage subsystem controller enclosure and remove the two drives (along with the
additional expansion enclosure, if attached).
4. Save the full configuration of the original storage subsystem into a SMcli script file. Make
sure that you check the check boxes for the storage subsystem settings, logical drive
configurations, logical drive-to-LUN map definitions, and topology before proceeding with
the configuration save. Make sure that the location you are saving to is not any of the
logical drives that are mapped from the original storage subsystem.
5. Delete any FlashCopy images of the logical drives.
