the
scan
dump
policy
(scan

Scan
Dump
data
is
a
set
of
chip
data
that
the
service
processor
gathers
after
a
system
malfunction.
It
consists
of
chip
scan
rings,
chip
trace
arrays,
and
Scan
COM
(SCOM)
registers.
This
data
is
stored
in
the
scan-log
partition
of
the
system’s
Nonvolatile
Random
Access
Memory
(NVRAM).
Use
this
service
aid
to
display
and

are
as
follows:
v
As
Needed:
This
setting
allows
the
platform
firmware
to
determine
whether
a
scan
dump
is
performed.
This
is
the
default
setting
for
the
dump
policy.
v
Always:
This
setting
overrides
the
firmware
recommendations
and
always
performs
a
dump
after
a
system
failure.
The
Scan
Dump
Size
(SDS)
settings
are
as
follows:
v
As
Requested
-
Dump
content
is
determined
by
the
platform
firmware.
v
Minimum
-
Dump
content
collected
provides
the
minimum
debug
information,
enabling
the
platform
to
reboot
as
quickly
as
possible.
v
Optimum
-
Dump
content
collected
provides
a
moderate
amount
of
debug
information.
v
Complete
-
Dump
data
provides
the
most
complete
error
coverage
at
the
expense
of
reboot
speed.
