are
 
handled
 
automatically
 
by
 
the
 
iprupdate
 
utility,
 
which
 
executes
 
each
 
time
 
the

is
 
booted,
 
or
 
manually
 
by
 
the
 
iprconfig
 
utility.
 
The

utility
 
will
 
only
 
automatically
 
update
 
microcode
 
to
 
adapters
 
and
 
devices
 
if
 
it

Configuring
 
the
 
PCI-X
 
Dual
 
Channel
 
Ultra320
 
SCSI
 
Adapter
 
The
 
PCI-X
 
Dual
 
Channel
 
Ultra320
 
SCSI
 
Adapter
 
permits
 
up
 
to
 
320
 
MB/s
 
operation
 
with
 
LVD
 
devices
 
on
 
a
 
wide
 
bus.
 
With
 
single-end
 
(SE)
 
devices,
 
it
 
can
 
run
 
up
 
to
 
40
 
MB/s.
 
The
 
maximum
 
speed
 
and
 
bus
 
width
 
are
 
automatically
 
negotiated
 
based
 
on
 
the
 
characteristics
 
of
 
the
 
attached
 
device.
 
You
 
can
 
use
 
iprconfig
 
to
 
control
 
speed
 
and
 
bus
 
width
 
for
 
devices
 
as
 
described
 
in
 
the
 
following
 
sections.
 
Limit
 
Adapter
 
Speed
 
Using
 
the
 
Maximum
 
SCSI
 
Bus
 
Speed
 
in
 
MB/s
 
The
 
default
 
maximum
 
adapter
 
speed
 
is
 
320
 
MB/s
 
for
 
LVD
 
mode
 
and
 
40
 
MB/s
 
for
 
SE
 
mode.
 
If
 
you
 
are
 
not
 
successful
 
running
 
at
 
these
 
speeds,
 
you
 
can
 
reduce
 
the
 
adapter
 
speed
 
by
 
changing
 
the
 
Maximum
 
Bus
 
Throughput.
 
Note:
  
The
 
device
 
driver
 
will
 
default
 
to
 
80
 
MB/s
 
on
 
the
 
2.4
 
kernel
 
until
 
the
 
iprupdate
 
utility
 
runs
 
and
 
160
 
MB/s
 
on
 
the
 
2.6
 
kernel
 
until
 
the
 
iprinit
 
utility
 
is
 
run.
 
After
 
the
 
utilities
 
complete,
 
higher
 
speeds
 
will
 
be
 
attempted.
 
These
 
utilities
 
are
 
configured
 
to
 
run
 
automatically
 
each
 
time
 
the
 
system
 
is
 
booted.
 
To
 
limit
 
adapter
 
speed,
 
do
 
the
 
following:
 
1.
   
At
 
the
 
command
 
prompt,
 
type
 
iprconfig
,
 
and
 
press
 
Enter.
