An Implementation Engineer has completed cabling a DirectFlash Shelf (DFS) to the FlashArray.

Verifying the physical SAS or RoCE cabling topology is a mandatory step before initializing a new shelf. The FlashArray provides a specific engineering-level Python script for this purpose: storage_view.py enclosures .

This script queries the backend fabric and visualizes the connection topology between the controllers and the shelves.

It confirms that both controllers (CT0 and CT1) have redundant paths to the shelf (IOM0 and IOM1).

It verifies that the shelf is visible on the expected ports.

It checks for cabling errors, such as "crossed" cables (connecting a primary port to a secondary port incorrectly) or missing links.

Using this tool ensures that the physical layer is perfectly redundant before data is ever placed on the shelf.
