An
N_Port
supports
a
point-to-point
connection
to
an
F_port
(for
example,
a
director-class
switch)
in
a
switched
fabric
topology.
Regardless
of
the
port
to
which
you
connect
the
drive,
it
automatically
configures
to
a
public
device
(through
an
F_port
or
FL_port
to
a
switch)
or
to
a
private
device
(through
an
L_port
by
using
direct
attachment
to
a
server).
The
table
below
lists
the
topologies
in
which
the
Ultrium
Tape
Drive
can
operate,
the
Fibre
Channel
server
connections
that
are
available,
and
the
port
through
which
communication
must
occur.

LUN
Assignments
The
logical
unit
number
(LUN)
for
the
Sequential
Access
device
is
always
LUN
0
of
the
drive,
and
the
LUN
for
the
Medium
Changer
device
is
always
LUN
1
(all
other
LUNs
are
invalid
addresses).
These
devices
are
compatible
with
the
SCSI-3
standard.
For
information
about
the
SCSI
commands
for
the
tape
drive
and
the
library,
see
the
IBM
TotalStorage
LTO
Ultrium
Tape
Drive
SCSI
Reference
and
the
IBM
System
Storage
TS3310
Tape
Library
SCSI
Reference
.
Note:
The
Medium
Changer
SCSI
ID
is
the
same
as
the
SCSI
ID
for
the
control
path
drive.
You
can
enable
additional
drives
to
optionally
provide
Medium
Changer
(LUN
1)
addressing
by
configuring
more
than
one
logical
library
or
by
enabling
additional
control
paths
(see
Using
World
Wide
Names
Normally,
blocks
of
World
Wide
Name
(WWN)
addresses
are
assigned
to
manufacturers
by
the
IEEE
Standards
Committee,
and
are
built
into
devices
during
manufacture.
In
the
case
of
the
library,
however,
it
assigns
World
Wide
Node
Names
and
World
Wide
Port
Names
to
the
drives.
This
technique
is
referred
to
as
persistent
world
wide
names.
Potential
drive
slots
are
each
assigned
a
WWN
which
does
not
change
when
a
drive
is
swapped
or
replaced.
The
WWN
of
the
drive
is
location-dependent
and
not
device-dependent.
That
is,
each
time
that
the
drive
is
reset
or
powered
on,
the
library
reestablishes
the
WWN
so
that
a
drive
in
Slot
x
always
keeps
the
same
WWN,
even
if
the
drive
is
replaced.
The
design
of
a
WWN
is
such
that
if
a
drive
needs
service
or
replacement,
host
parameters
do
not
need
to
be
changed
or
reconfigured.
The
library’s
configuration
can
also
easily
survive
a
reboot.
