Performing the checkout procedure

To perform the checkout procedure, complete the following steps:
1. Is the server part of a cluster?
2. Complete the following steps:

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.

v No: Go to step 2.
v Yes: Shut down all failing servers that are related to the cluster. Go to step 2.
a. Check the power supply LEDs (see "Power-supply LEDs" on page 135).
b. Turn off the server and all external devices.
c. Check all internal and external devices for compatibility at
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.
d. Check all cables and power cords.
e. Set all display controls to the middle positions.
f. Turn on all external devices.
g. Turn on the server. If the server does not start, see "Troubleshooting tables"
on page 103.
h. Check the system-error LED on the operator information panel. If it is lit or
flashing, check the light path diagnostics LEDs (see "Light path diagnostics"
on page 124).
i. Check for the following results:
v Successful completion of POST (see "POST" on page 28 for more
information).
v Successful completion of startup
