is

when
you
select
the
Problem

option
on
the
DIAGNOSTIC
MODE
SELECTION
menu.
Concurrent
Mode
Use
concurrent
mode
to
run
online
diagnostics
on
some
of
the
system
resources
while
the
system
is
running
normal
activity.
Because
the
system
is
running
in
normal
operation,
the
following
resources
cannot
be
tested
in
concurrent
mode:
v
SCSI
adapters
connected
to
paging
devices
v
Disk
drive
used
for
paging
v
Some
display
adapters
and
graphics
related
devices
v
Memory
(tested
during
POST)
v
Processor
(tested
during
POST)
The
following
levels
of
testing
exist
in
concurrent
mode:
v
The
share-test
level
tests
a
resource
while
the
resource
is
being
shared
by
programs
running
in
the
normal
operation.
This
testing
is
mostly
limited
to
normal
commands
that
test
for
the
presence
of
a
device
or
adapter.
v
The
sub-test
level
tests
a
portion
of
a
resource
while
the
remaining
part
of
the
resource
is
being
used
in
normal
operation.
For
example,
this
test
could
test
one
port
of
a
multiport
device
while
the
other
ports
are
being
used
in
normal
operation.
v
The
full-test
level
requires
the
device
not
be
assigned
to
or
used
by
any
other
operation.
This
level
of
testing
on
a
disk
drive
might
require
the
use
of
the
varyoff
command.
The
diagnostics
display
menus
to
allow
you
to
vary
off
the
needed
resource.
Error-log
analysis
is
done
in
concurrent
mode
when
you
select
the
Problem
Determination
option
on
the
DIAGNOSTIC
MODE
SELECTION
menu.
To
run
the
online
diagnostics
in
concurrent
mode,
you
must
be
logged
in
to
the
AIX
operating
system
and
have
proper
authority
to
issue
the
commands
(if
help
is
needed,
see
the
system
operator).
The
diag
command
loads
the
diagnostic
controller
and
displays
the
online
diagnostic
menus.
Maintenance
Mode
Maintenance
mode
runs
the
online
diagnostics
using
the
customer’s
version
of
the
AIX
operating
system.
This
mode
requires
that
all
activity
on
the
partition
running
the
AIX
operating
system
be
stopped
so
that
the
online
diagnostics
have
most
of
the
resources
available
to
check.
All
of
the
system
resources,
except
the
SCSI
adapters,
memory,
processor,
and
the
disk
drive
used
for
paging,
can
be
checked.
Error
log
analysis
is
done
in
maintenance
mode
when
you
select
the
Problem
Determination
option
on
the
DIAGNOSTIC
MODE
SELECTION
menu.
Use
the
shutdown
-m
command
to
stop
all
activity
on
the
AIX
operating
system
and
put
the
AIX
operating
system
into
maintenance
mode.
The
diag
command
is
then
used
to
invoke
the
diagnostic
controller
so
you
can
run
the
diagnostics.
After
the
diagnostic
controller
is
loaded,
follow
the
normal
diagnostic
instructions.

the
AIX
operating
system
