In the following sections we discuss LAN-free client data transfer using Tivoli
Storage Manager and the Storage Agent. In particular, we cover these topics:

Configuring devices on the client machine for LAN-free
򐂰
Setting up and configuring the Storage Agent on a client machine
򐂰
Customizing the client for LAN-free

Operations and considerations when using LAN-free data transfer

16.2 Server setup for LAN-free
Before setting up the server for LAN-free operations, the Tivoli Storage Manager
server itself must be installed and running. The machine hosting the server
instance needs to be connected to the SAN.
The instructions in this section assume that you can detect and use your
SAN-attached library devices, and that all SAN devices and components have
current microcode and firmware levels installed.
Once the hardware, firmware, and operating systems are prepared, the Tivoli
Storage Manager configuration is virtually identical, regardless of the platform
used. Here we describe configuring the Tivoli Storage Manager server on an
AIX 5L platform.
In a Tivoli Storage Manager SAN environment, where the library is shared
between several hosts, the Tivoli Storage Manager server is referred to as the
library manager
. The library manager owns and controls the library device and
processes all requests from the library clients, such as mounting and
dismounting volumes.
In our case, the library clients are Storage Agents. Library clients request shared
library resources, such as a drive or media, from the library manager, but use
them independently of the library manager.
In this library-sharing environment, the most important relationship is the one
between the server and the Storage Agent—or library manager and library client.
Establishing communication between library manager and library clients is called
server-to-server communication in Tivoli Storage Manager terminology.
We prepare our server instance for server-to-server communication, setting up
the server name, which must be unique across the whole Tivoli Storage Manager
