Checkout procedure
The checkout procedure is the sequence of tasks that you should follow to diagnose a problem in the server.
About the checkout procedure
Before you perform the checkout procedure for diagnosing hardware problems, review the following
information.
• Read the safety information that begins on page
• Dynamic System Analysis (DSA) provides the primary methods of testing the major components of the
server, such as the system board, Ethernet controller, keyboard, mouse (pointing device), serial ports, and
hard disk drives. You can also use them to test some external devices. If you are not sure whether a
problem is caused by the hardware or by the software, you can use the diagnostic programs to confirm
that the hardware is working correctly.
• When you run DSA, a single problem might cause more than one error message. When this happens,
correct the cause of the first error message. The other error messages usually will not occur the next time
you run DSA.
Important: If multiple error codes or light path diagnostics LEDs indicate a microprocessor error, the
error might be in the microprocessor or in the microprocessor socket. See
page 137
for information about diagnosing microprocessor problems.
• Before you run DSA, you must determine whether the failing server is part of a shared hard disk drive
cluster (two or more servers sharing external storage devices). If it is part of a cluster, you can run all
diagnostic programs except the ones that test the storage unit (that is, a hard disk drive in the storage
unit) or the storage adapter that is attached to the storage unit. The failing server might be part of a cluster
if any of the following conditions is true:
– You have identified the failing server as part of a cluster (two or more servers sharing external storage
devices).
– One or more external storage units are attached to the failing server and at least one of the attached
storage units is also attached to another server or unidentifiable device.
– One or more servers are located near the failing server.
Important: If the server is part of a shared hard disk drive cluster, run one test at a time. Do not run any
suite of tests, such as "quick" or "normal" tests, because this might enable the hard disk drive diagnostic
tests.
• If the server is halted and a POST error code is displayed, see
on page
533. If the server is halted and no error message is displayed, see
on page 129
