v Run all the operating system commands run by system group users. v Configure and unconfigure devices that are not busy. In addition, CE login can have Shutdown Group enabled to allow: v Use of the Update System Microcode service aid. v Use of shutdown and reboot operations. To use CE login, ask the customer to create a user section of the AIX 5L Version 5.3 System Management Guide: Operating System and Devices. After this is set up, you will need to obtain the user name and password from the customer to log in with these capabilities. The recommended CE login user name is qserv. Missing resources In diagnostics version 5.2.0 and later, missing devices are identified on the Diagnostic Selection screen by an uppercase ″M″ preceding the name of the device that is missing. The Diagnostic Selection menu is displayed any time you run the diagnostic routines or the advanced diagnostics routines. The Diagnostic Selection menu can also be entered by running diag -a when there are missing devices or missing paths to a device. When a missing device is selected for processing, the Missing Resource menu will ask whether the device has been turned off, removed from the system, moved to a different physical location, or if it is still present. When a single device is missing, the fault is probably with that device. When multiple devices with a common parent are missing, the fault is most likely related to a problem with the parent device. The diagnostic procedure may include testing the device's parent, analyzing which devices are missing, and any manual procedures that are required to isolate the problem. v Symptom response: The Missing Resource menu is displayed or the letter ″M″ is displayed alongside a resource in the resource list. v Action: If the Missing Resource menu is displayed, follow the displayed instructions until either the Diagnostic Selection menu or an SRN is displayed. If an ″M″ is displayed in front of a resource (indicating that it is missing), select that resource; then, choose Commit (F7 key). - If an 8-digit error code is displayed, go to the"Firmware error codes" on page 102, find the error and perform the listed action. - If an SRN is displayed, record it and go to "SRN tables" on page 110. Automatic diagnostic tests All automatic diagnostic tests are run after the system unit is turned on and before the AIX operating system is loaded. The automatic diagnostic tests display progress indicators (or checkpoints) to track test progress. If a test stops or hangs, the checkpoint for that test remains on the console to identify the unsuccessful test. Configuration program The configuration program determines what features, adapters, and devices are present on the system. The configuration program, which is part of the AIX operating system, builds a configuration list that is used by the diagnostic programs to control which tests are run during system checkout. 60 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide

Version
5.3
System
Management
Guide:
Operating
System

Missing
resources
In
diagnostics
version
5.2.0
and
later,
missing
devices
are
identified
on
the
Diagnostic
Selection
screen
by
an
uppercase
″
M
″
preceding
the
name
of
the
device
that
is
missing.
The
Diagnostic
Selection
menu
is
displayed
any
time
you
run
the
diagnostic
routines
or
the
advanced
diagnostics
routines.
The
Diagnostic
Selection
menu
can
also
be
entered
by
running
diag
-a
when
there
are
missing
devices
or
missing
paths
to
a
device.
When
a
missing
device
is
selected
for
processing,
the
Missing
Resource
menu
will
ask
whether
the
device
has
been
turned
off,
removed
from
the
system,
moved
to
a
different
physical
location,
or
if
it
is
still
present.
When
a
single
device
is
missing,
the
fault
is
probably
with
that
device.
When
multiple
devices
with
a
common
parent
are
missing,
the
fault
is
most
likely
related
to
a
problem
with
the
parent
device.
The
diagnostic
procedure
may
include
testing
the
device’s
parent,
analyzing
which
devices
are
missing,
and
any
manual
procedures
that
are
required
to
isolate
the
problem.
v
Symptom
response:
The
Missing
Resource
menu
is
displayed
or
the
letter
″
M
″
is
displayed
alongside
a
resource
in
the
resource
list.
v
Action:
If
the
Missing
Resource
menu
is
displayed,
follow
the
displayed
instructions
until
either
the
Diagnostic
Selection
menu
or
an
SRN
is
displayed.
If
an
″
M
″
is
displayed
in
front
of
a
resource
(indicating
that
it
is
missing),
select
that
resource;
then,
choose
Commit
(F7
key).
–
If
an
8-digit
error
code
is
displayed,
go
to
the“Firmware
error
codes”
on
page
102,
find
the
error
and
perform
the
listed
action.
–
If
an
SRN
is
displayed,
record
it
and
go
to
“SRN
tables”
on
page
110.
Automatic
diagnostic
tests
All
automatic
diagnostic
tests
are
run
after
the
system
unit
is
turned
on
and
before
the
AIX
operating
system
is
loaded.
The
automatic
diagnostic
tests
display
progress
indicators
(or
checkpoints)
to
track
test
progress.
If
a
test
stops
or
hangs,
the
checkpoint
for
that
test
remains
on
the
console
to
identify
the
unsuccessful
test.
Configuration
program
The
configuration
program
determines
what
features,
adapters,
and
devices
are
present
on
the
system.
The
configuration
program,
which
is
part
of
the
AIX
operating
system,
builds
a
configuration
list
that
is
used
by
the
diagnostic
programs
to
control
which
tests
are
run
during
system
checkout.
