Fixing
a
Consistent
Error
with
Multiple
Drives
on
a
Fibre
Channel
Loop
Use
the
following
procedure
to
determine
if
all
of
the
drives
on
the
Fibre
Channel
have
the
problem:
1.
Use
a
device
driver
utility
(such
as
ntutil
or
tapeutil
)
to
verify
that
the
drive
is
available
and
properly
configured
at
the
server.
2.
Determine
the
type
of
Fibre
Channel
topology
that
you
are
using
(see
page
7).
3.
Using
this
guide
or
the
service
guides
of
associated
switch,
hub,
or
fiber
products,
try
to
isolate
which
part
of
the
Fibre
Channel
Storage
Area
Network
(SAN)
is
experiencing
problems.
4.
Perform
one
of
the
following:
v
If
the
problem
exists
on
a
small
number
of
drives,
go
to
“Fixing
a
Consistent
Error
with
a
Single
Drive
on
a
Fibre
Channel
Loop”
on
page
88.
v
If
the
problem
exists
with
a
large
number
of
drives,
perform
the
following
steps:
a.
Disconnect
all
except
one
failing
drive
on
the
Fibre
Channel.
b.
Run
the
Fibre
Channel
wrap
test
to
determine
if
a
failure
occurs
on
that
drive
(see
Function
Code
6
in
“Function
Code
6:
Run
SCSI
Wrap
Test”
on
page
37).
If
it
does,
perform
the
procedure
in
“Fixing
a
Consistent
Error
with
a
Single
Drive
on
a
Fibre
Channel
Loop”
on
page
88.
c.
Continue
to
connect
one
drive
at
a
time
to
the
Fibre
Channel
loop.
5.
When
the
problem
is
corrected,
restore
all
of
the
Fibre
Channel
cables
to
their
correct
position.
Fixing
a
Consistent
Error
in
a
Point-to-Point
Topology
1.
Ensure
that
the
tape
drive
is
powered
on.
2.
Verify
that
the
tape
drive’s
serial
number
is
the
same
as
the
drive
serial
number
that
the
server
program
is
using.
3.
Ensure
that
the
drive
is
connected
to
the
host
or
switch.
The
drive
must
be
able
to
detect
light
and
communicate
with
the
server.
4.
Run
the
Fibre
Channel
wrap
test
at
the
drive’s
Fibre
Channel
connector
(see
Function
Code
6
in
“Function
Code
6:
Run
SCSI
Wrap
Test”
on
page
37).
v
If
the
test
fails,
replace
the
tape
drive.
v
If
the
test
is
successful,
go
to
step
5.
5.
Run
the
Fibre
Channel
wrap
test
at
the
end
of
the
fiber
cable
(see
Function
Code
6
in
“Function
Code
6:
Run
SCSI
Wrap
Test”
on
page
37).
v
If
the
test
fails,
replace
the
fiber
cable.
v
If
the
test
is
successful,
go
to
step
6.
6.
Check
the
Fibre
Channel
cable
connection
at
the
server.
7.
Using
a
device
driver
utility
such
as
ntutil
or
tapeutil
,
verify
that
the
drive
is
properly
configured
and
available
at
the
server.
8.
If
the
problem
persists,
the
fault
may
be
with
the
server’s
hardware
or
software.
Refer
to
your
server’s
service
manual.
9.
When
the
problem
is
corrected
(or
determined
to
be
a
server
problem),
restore
all
of
the
fiber
cables
to
their
correct
position.
