SANDISCOVERY
Specifies
whether
the
Tivoli
Storage
Manager
SAN
discovery
function
is
enabled.
When
set
to
ON,
the
storage
agent
will
perform
SAN
discovery
in
the
following
instances:
v
During
storage
agent
initialization
v
When
the
device
path
has
been
changed
and
there
is
a
conflict
between
the
device
serial
number
and
the
device
path
provided
by
the
server
Using
SAN
discovery,
the
storage
agent
can
automatically
correct
the
device’s
special
file
name
if
it
has
been
changed.
If
the
HBA
used
by
the
storage
agent
does
not
support
SAN
device
mapping,
you
should
set
the
SANDISCOVERY
option
to
OFF.
For
information
about
Tivoli
Storage
Manager
supported
HBAs
for
SAN
device
mapping,
see
www.ibm.com/software/sysmgmt/products/
support/IBMTivoliStorageManager.html
The
storage
agent
does
not
require
persistent
binding
with
the
SAN
discovery
function
enabled.
STAMaxpooledsessions
number
Specifies
the
number
of
individual
sessions
that
are
allowed
to
start
and
stop
between
the
storage
agent
and
the
Tivoli
Storage
Manager
server.
The
range
of
values
is
0
-
150,
with
a
default
of
25.
Each
session
is
governed
by
the
IDLETIMEOUT
option
and
is
stopped
when
the
timeout
value
is
exceeded.
If
the
storage
agent
needs
more
sessions
than
specified,
additional
sessions
are
allowed.
Although
the
default
value
is
typically
sufficient,
setting
this
option
with
a
low
number
can
adversely
affect
performance.
Be
aware
that
if
the
storage
agent
has
multiple
client
sessions,
increasing
the
value
of
this
option
will
help
support
these
sessions.
TCPADMINPORT
number
Specifies
the
port
number
on
which
the
server
TCP/IP
communication
driver
is
to
wait
for
requests
for
sessions
other
than
client
sessions.
This
includes
administrative
sessions,
server-to-server
sessions,
SNMP
subagent
sessions,
storage
agent
sessions,
library
client
sessions,
managed
server
sessions,
and
event
server
sessions.
The
default
is
the
value
of
TCPPORT.
Using
different
port
numbers
for
the
options
TCPPORT
and
TCPADMINPORT
enables
you
to
create
one
set
of
firewall
rules
for
client
sessions
and
another
set
for
the
other
session
types
listed
above.
By
using
the
SESSIONINITIATION
parameter
of
REGISTER
and
UPDATE
NODE,
you
can
close
the
port
specified
by
TCPPORT
at
the
firewall,
and
specify
nodes
whose
scheduled
sessions
will
be
started
from
the
server.
If
the
two
port
numbers
are
different,
separate
threads
will
be
used
to
service
client
sessions
and
the
session
types.
If
you
allow
the
two
options
to
use
the
same
port
number
(by
default
or
by
explicitly
setting
them
to
the
same
port
number),
a
single
server
thread
will
be
used
to
service
all
session
requests.
Client
sessions
which
attempt
to
use
the
port
specified
by
TCPADMINPORT
will
be
terminated
(if
TCPPORT
and
TCPADMINPORT
specify
different
ports).
Administrative
sessions
are
allowed
on
either
port,
(unless
the
ADMINONCLIENTPORT
option
is
set
to
NO)
but
by
default
will
use
the
port
specified
by
TCPADMINPORT.
THROUGHPUTDatathreshold
kilobytes_per_second
Specifies
the
throughput
that
client
sessions
must
achieve
to
prevent
cancellation
after
THROUGHPUTTimethreshold
minutes
have
elapsed.
