Set drive to failed: controller [number], <device location>

Explanation:

There was an error in communication between the physical drive and the controller.

Action:

1. Verify that there is power to external enclosures and connections.
2. Verify that cables are properly seated.
3. Check for damaged, bent, or pushed pins on the following:
   • Termination (for non-backplane systems)
   • Backplanes
   • Physical drives
   • Controller

If you cannot identify a connection problem, the replacement order for parts is the following:

1. Termination (for non-backplane systems)
2. Cables
3. Physical drives
4. Backplanes
5. Controller

Before replacing a physical drive or controller, verify that it is updated with the latest firmware (microcode) and that they still fail.

Note: If multiple physical drives are marked failed within the same time period, check the cables and backplanes.
