Solving SAS problems For any SAS error message, one or more of the following devices might be causing the problem: v A failing SAS device (adapter, drive, or controller) v An incorrect SAS termination jumper setting v A missing or incorrectly installed SAS terminator v A defective SAS terminator v An incorrectly installed cable v A defective cable For any SAS error message, follow these suggested actions in the order in which they are listed until the problem is solved: 1. Make sure that external SAS devices are turned on before you turn on the server. 2. Make sure that the cables for all external SAS devices are connected correctly. 3. If an external SAS device is attached, make sure that the external SAS termination is set to automatic. 4. Make sure that the last device in each SAS chain is terminated correctly. 5. Make sure that the SAS devices are configured correctly. Solving power problems Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power distribution buses. Usually, a short circuit will cause the power subsystem to shut down because of an overcurrent condition. To diagnose a power problem, use the following general procedure: 1. Turn off the server and disconnect all ac power cords. 2. Check for loose cables in the power subsystem. Also check for short circuits, for example, if a loose screw is causing a short circuit on a circuit board. 3. Remove the adapters and disconnect the cables and power cords to all internal and external devices until the server is at the minimum configuration that is required for the server to start (see "Solving undetermined problems" on page 229 for the minimum configuration). 4. Reconnect all ac power cords and turn on the server. If the server starts successfully, replace the adapters and devices one at a time until the problem is isolated. If the server does not start from the minimum configuration, replace the components in the minimum configuration one at a time until the problem is isolated. Chapter 5. Diagnostics 227

Solving SAS problems

For any SAS error message, one or more of the following devices might be causing

the problem:

A failing SAS device (adapter, drive, or controller)

An incorrect SAS termination jumper setting

A missing or incorrectly installed SAS terminator

A defective SAS terminator

An incorrectly installed cable

A defective cable

For any SAS error message, follow these suggested actions in the order in which

they are listed until the problem is solved:

Make sure that external SAS devices are turned on before you turn on the

server.

Make sure that the cables for all external SAS devices are connected correctly.

If an external SAS device is attached, make sure that the external SAS

termination is set to automatic.

Make sure that the last device in each SAS chain is terminated correctly.

Make sure that the SAS devices are configured correctly.

Solving power problems

Power problems can be difficult to solve. For example, a short circuit can exist

anywhere on any of the power distribution buses. Usually, a short circuit will cause

the power subsystem to shut down because of an overcurrent condition. To

diagnose a power problem, use the following general procedure:

Turn off the server and disconnect all ac power cords.

Check for loose cables in the power subsystem. Also check for short circuits, for

example, if a loose screw is causing a short circuit on a circuit board.

Remove the adapters and disconnect the cables and power cords to all internal

and external devices until the server is at the minimum configuration that is

required for the server to start (see “Solving undetermined problems” on page

229 for the minimum configuration).

Reconnect all ac power cords and turn on the server. If the server starts

successfully, replace the adapters and devices one at a time until the problem is

isolated.

If the server does not start from the minimum configuration, replace the components

in the minimum configuration one at a time until the problem is isolated.
