A server's multi-pathing software indicates a failed path to the storage. Which of the following steps should be done FIRST to troubleshoot the issue?

Verifying the port LEDs along the connection is the most fundamental and immediate first step when troubleshooting a reported path failure. Lit LEDs typically indicate a physical link, while unlit or error-indicating LEDs can quickly pinpoint a physical issue such as a disconnected cable, faulty HBA port, or switch port, providing crucial diagnostic information without requiring complex system changes.

Replacing the fiber cable is a potential solution but should only be done after initial diagnostics, like checking LEDs, confirm a cable or port issue.

Replacing the HBA is a more drastic and costly step and should be considered only after verifying simpler physical components and software configurations.

Updating drivers and firmware is a software-related troubleshooting step, which should typically follow physical layer checks, especially when a path failure is initially indicated.
