1.
Type
scsiha
-r
{bus_number
|
device}
at
the
root
of
the
shell
prompt.
bus_number
is
the
numerical
value
for
the
bus
and
device
is
numerical
value
of
the
device.
2.
Type
scsiha
-p
{bus_number
|
device}
.
3.
Use
the
ioconfig
-d
-f
/hw
command
to
assign
logical
controller
numbers
in
the
hardware
graph
to
each
of
the
newly
discovered
physical
devices.
4.
Use
the
hinv
-c
disk
command
to
confirm
that
all
four
instances
of
each
of
the
four
LUNs
exists.
5.
Use
the
ls
-l
/hw/rdisk
command
to
verify
that
you
named
the
directory
the
same
name
as
the
worldwide
node
name
of
the
storage
unit.
6.
Use
the
ls
-l
/hw/rdisk
command
to
verify
that
directories
for
each
LUN
exist
in
the
/hw/rdisk/<wwnn>
directory,
where
<wwnn>
is
the
worldwide
node
name
of
the
device.
7.
Type
cd
/hw/rdisk/<wwnn>
,
where
<wwnn>
is
the
worldwide
node
name
of
the
device,
to
change
to
the
/hw/rdisk/<wwnn>
directory.
You
must
execute
the
next
command
from
within
this
directory.
8.
Use
the
ls
-lR
lun*
command
to
verify
that
the
command
created
the
character-special
files
in
each
LUN*
directory.
The
asterisk
(*)
acts
as
a
universal
wildcard
for
any
characters
that
might
appear
after
the
initial
“LUN”

Confirming
storage
connectivity
for
SGI
in
a
fibre-channel
arbitrated
loop
topology
This
section
contains
an
example
of
an
arbitrated
loop
connection
with
the
fibre-channel
adapter
cards.
The
following
conditions
apply
to
this
example:
v
The
PCI-FC-1P-OPT
adapter
cards
are
on
PCI
busses
6
and
8.
v
There
are
four
LUNs
defined
on
the
storage
unit.
v
Each
host
adapter
is
connected
to
a
host
adapter
in
the
storage
unit.
v
Each
host
adapter
maintains
two
instances
of
each
LUN.
1.
Type
scsiha
-r
{bus_number
|
device}
at
the
root
of
the
shell
prompt.
bus_number
is
the
numerical
value
for
the
bus
and
device
is
the
numerical
value
for
the
device.
2.
Type
scsiha
-p
{bus_number
|
device}
.
3.
Use
the
ioconfig
-d
-f
/hw
command
to

confirm
that
two
instances
of

of
the
four
LUNs
exist.
5.
Use
the
ls
-l
/hw/disk
command
to
verify
that
the
command
created
the
appropriate
block
special
files
in
hw/disk
for
each
LUN.
