Define
paths
on
the
server
using
the
device
names
as
seen
by
the
storage
agent
on
each
client
system.
Important:
Be
sure
that
the
device
names
are
what
the
storage
agent
sees
on
each
client
system.
Note:
The
DEFINE
PATH
command
must
be
issued
from
the
server
designated
as
the
library
manager.
For
example,
you
would
issue
the
following:
define
path
storagnt
drive1
srctype=server
desttype=drive
library=sanlib1
device=/dev/tsmscsi/mt1
See
the
Administrator’s
Reference
for
your
system
platform
for
additional
details
on
the
DEFINE
PATH
command.
Depending
on
the
operating
system
of
the
Tivoli
Storage
Manager
server,
there
may
not
be
a
quick
way
to
confirm
which
device
names
on
the
storage
agent
correspond
to
device
names
on
the
Tivoli
Storage
Manager
server
without
using
a
trial
and
error
method.
To
confirm
device
names,
you
should
work
with
one
online
drive
at
a
time,
and
cycle
through
the
storage
agent
device
names
until
a
successful
backup
can
be
run.
The
server
cannot
validate
PATH
information
that
is
provided
on
the
server
for
use
by
the
storage
agent.
Failures
can
occur
if
incorrect
device
information
is
provided
in
the
DEFINE
PATH
command.
You
can
also
specify
the
AUTODETECT=YES
option
when
defining
paths
on
the
server.
This
allows
the
serial
number
for
a
drive
or
library
to
be
automatically
updated
in
the
database
when
the
path
is
defined.
The
updated
serial
number
will
be
the
same
serial
number
that
the
drive
reports
to
Tivoli
Storage
Manager.
After
a
backup
is
completed
in
“Step
5.2
Verify
the
LAN-free
Configuration”
on
page
29,
you
can
issue
the
QUERY
DRIVE
command
to
obtain
information
that
will
help
determine
the
device
name
from
the
storage
agent.
