configure
external
library
support.
This
section
illustrates
how
to
use
Gresham
EDT-DistribuTAPE
as
an
external
library
manager
via
StorageTek
ACSLS.
External
library
support
is
an
alternative
library
resource
when
the
environment
is
unable
to
satisfy
library
resource
sharing
requirements
with
Tivoli
Storage
Manager
library
sharing
support
for
SCSI,
3494,
and
ACSLS
(Library
Station)
managed
libraries.
A
typical
external
library
configuration
includes
using
an
external
library
manager
such
as
Gresham
EDT-DistribuTAPE.
See
The
ACSLS
Server
or
the
LibraryStation
on
z/OS
manages
the
physical
aspects
of
tape
cartridge
storage
and
retrieval.
The
external
library
manager,
for
instance,
Gresham
EDT,
communicates
with
the
ACSLS
Server
or
the
LibraryStation
on
z/OS
to
access
tape
cartridges
in
an
automated
StorageTek
library.
The
storage
agent
installed
on
a
machine
containing
Gresham
EDT
and
a
Tivoli
Storage
Manager
backup-archive
client
or
a
Tivoli
Storage
Manager
data
protection
application
client
provides
access
to
SAN-attached
storage
devices
resulting
in
LAN-free
data
movement.
The
continued
connection
to
the
LAN
provides
a
metadata
(control
information)
path.
If
the
storage
agent
is
not
available,
the
LAN
provides
a
failover
path
for
data
backup
and
recovery.
