Configuring POST
POST Overview
POST is a group of PROM-based tests that run when the server is powered on or when it is
reset. POST checks the basic integrity of the critical hardware components in the server.
You can also set other Oracle ILOM properties to control various other aspects of POST
operations. For example, you can specify the events that cause POST to run, the level of testing
POST performs, and the amount of diagnostic information POST displays. These properties are
described in “Oracle ILOM Properties That Affect POST Behavior” on page 41.
If POST detects a faulty component, the component is disabled automatically. If the server is
able to run without the disabled component, the server boots when POST completes its tests.
For example, if POST detects a faulty processor core, the core is disabled, POST completes its
test sequence, and the server boots using the remaining cores.

PSH Overview
PSH provides problem diagnosis on the SP and the host. Regardless of where a fault occurs,
you can view and manage the fault diagnosis from the SP or the host.
When possible, PSH initiates steps to take the component offline. PSH also logs the fault to the
syslogd daemon and provides a fault notification with a message ID. You can use the message
ID to get additional information about the problem from the knowledge article database.
A PSH console message provides this information about each detected fault:
■

■
Severity
■

Clear a Fault
When PSH detects faults, the faults are logged and displayed on the console. In most cases,
after the fault is repaired, the corrected state is detected by the server, and the fault condition
is repaired automatically. However, this repair should be verified. In cases where the fault
condition is not automatically cleared, you must clear the fault manually.
1.
After replacing a faulty FRU, power on the server.
2.
At the host prompt, determine whether the replaced FRU still shows a faulty
state.
See “Check for Faults” on page 46.
■If no fault is reported, you do not need to do anything else. Do not perform
the subsequent steps.
■If a fault is reported, continue to Step 3.
3.
Clear the fault from all persistent fault records.
In some cases, even though the fault is cleared, some persistent fault information remains
and results in erroneous fault messages at boot time. To ensure that these messages are not
displayed, type this PSH command:
Clear a Fault
# fmadm acquit event-ID
4.
If required, reset the server.
In some cases, the output of the fmadm faulty command might include this message for the
faulty component:
faulted and taken out of service
If this message appears in the output, you must reset the server after you manually repair the
fault.

Memory Riser and DIMM FRU Names
The 2-processor server includes eight memory risers. The 1-processor server includes four
memory risers. Four memory risers are associated with each CMP in the server. A label is next
to each memory riser that shows the number of the CMP and of the riser. Four DIMM slots are
on each memory riser.
Note - The server fails to boot unless all memory riser slots are populated. For more
information about memory riser configuration, see “Memory Riser and DIMM
Configuration” on page 99.
DIMM FRU names are based on the location of the memory riser in the server and the DIMM
slot on the memory riser. For example, the full FRU name for the top-most DIMM slot (BOB1/
CH1/D0) on the first memory riser (CMP0/MR0) is:
/SYS/MB/CMP0/MR0/BOB1/CH1/D0

Memory Riser and DIMM Configuration
The memory riser configuration rules for the server are as follows:
■
The 2-processor server contains eight memory risers. The 1-processor server contains four
memory risers. Four memory risers are supported per CPU.
■
Each of the memory riser slots in the server must be filled with a memory riser.
There are only two possible memory configurations: Fully populated and half populated.
DIMM configuration rules for each memory riser are as follows:
■
For a fully populated configuration, DIMMs must be installed in all four DIMM connectors
on each memory riser.
■
For a half populated configuration (with 16GB or 32GB DIMMs), DIMMs must be installed
in the two black DIMM connectors (labeled J701_ZA and J701_ZB) on each memory riser.
■
All memory risers must contain the same rank, size, and type of DIMM.
