Suggested answer: B

Explanation:

The correct action to optimize the storage configuration when adding new enclosures and drives to an existing HPE 3PAR StoreServ 8400 array is to run the tunesys command. This utility performs a system-wide optimization that includes rebalancing the data across all physical disks to ensure optimal performance and space utilization. tunesys is especially useful when new drives are added because it ensures that the workload is evenly distributed across both the new and existing drives, preventing potential hotspots and improving overall system efficiency. Defragmenting the Common Provisioning Groups (CPGs) and aligning the drives would be beneficial in certain scenarios, but the first and most comprehensive step is to use tunesys.
