Setting
up
the
Linux
system
to
use
the
FCP
device
on
zSeries
hosts
This
topic
provides
instructions
for
setting
up
the
Linux
system
to
use
the
FCP
device
on
zSeries
hosts.
You
must
collect
the
following
software
configuration
information
to
prepare
a
Linux
system
for
accessing
the
storage
unit
through
fibre-channel:
v
Host
name
of
the
server
hosting
the
Linux
system
v
Device
address
(and
CHPID)
of
the
FCP
port
that
is
attached
to
the
Linux
machine
v
Worldwide
port
name
(WWPN)
of
the
FCP
port
on
the
zSeries
v
Fibre-channel
port
on
the
storage
unit
v
WWPN
of
the
fibre-channel
port
on
the
storage
unit
You
can
obtain
the
data
from
the
hardware
management
console
(HMC),
the
IBM
TotalStorage
DS
Storage
Manager,
and
the
SAN
switch.
Figure
48
shows
examples
of
the
prerequisite
information
you
must
have
to
run
FCP
Linux
on
the
zSeries.
You
must
have
at
least
the
following
modules
installed
to
use
the
FCP
device
with
the
storage
unit:
v
qdio
—
The
same
module
is
used
for
other
qdio
devices
v
scsi_mod
—
SCSI
core
v
zfcp
—
FCP
support
for
zSeries
Linux
v
sd_mod
—
SCSI
disk
support
1.
Load
the
modules
in
the
order
listed.
You
can
load
all
modules
with
the
modprobe
command.
You
can
load
all
modules,
except
zfcp,
without
parameters.
The
zfcp
module
requires
parameters
for
the
mapping
the
FCP
devices
on
the
storage
unit.
Each
device
requires
the
following
parameters:
a.
The
device
number
of
the
device
defined
in
the
IOCP
for
the
FCP
channel
on
the
zSeries
b.
The
SCSI
ID
starting
at
1
c.
The
WWPN
of
the
storage
unit
FC
port
d.
The
SCSI
LUN
within
Linux
starting
at
0
e.
The
FCP
LUN
of
the
target
volume
on
the
storage
unit
2.
Use
the
following
format
to
supply
the
mapping
parameters
to
the
module:
map="devno
SCSI_ID:WWPN
SCSI_LUN:FCP_LUN"
map="0x0600
1:0x5005076300c89589
0:0x5301000000000000"
