[hpe-guide] Inventory should establish the running revision; Cisco documents management and inquiry paths for its affected drives. [ciscofn] A downloaded update package alone does not demonstrate that the device is remediated. A serial-number advisory lookup may be a historical applicability list rather than a live remediation record: Cisco's 28,224-hour FAQ says its list is not updated after software fixes. [ciscossd]",
