To specifically verify the shelf cable connections and validate the SAS topology during an installation, the correct command is storage_view.py config .
While standard Purity CLI commands like purehw list (Option B) can show the presence and general status of enclosures, they often do not provide the granular, low-level details of the SAS cabling map required to troubleshoot or verify physical redundancy paths (Side A vs. Side B connectivity).
storage_view.py is a specialized Python utility script included in the Purity operating system, primarily intended for use by Implementation Engineers and Support. Running storage_view.py config (or similar arguments like enclosures) outputs a visual or tabular representation of the backend cabling, explicitly showing how the controllers are chained to the expansion shelves. This allows the engineer to confirm that the cabling matches the strict "stacking" rules (e.g., verifying that the SAS loops are closed and redundant) and to identify issues like cross-cabling or disconnected paths that a simple "status=healthy" flag might miss during the initial build.
