In a LAN Free environment the tape mount is operated by the TSM Server; as
you can see on the following document form the:

Managed System for SAN Storage Agent User's Guide


LAN-free Client Data Backup Scenario

   The following outlines a typical backup scenario for a TSM client that
uses SAN data movement. This scenario does not apply to External library
environments.
      1.The client begins a backup operation. The client and the server
exchange policy information over the LAN to determine the destination of
the backed up data.

        For a client using LAN-free data movement, the destination is a
storage pool that uses a device on the SAN. That device must also have a
defined path between
        the device and the storage agent.
      2.Because the destination is on the SAN, the client contacts the
storage agent, which will handle the data transfer. The storage agent sends
a request for a
        volume mount to the server.
      3.The server contacts the storage device and mounts the appropriate
media.
      4.The server notifies the client of the location where the mounted
media resides.
      5.The client, by means of the storage agent, writes the backup data
directly to the device over the SAN.
      6.The storage agent sends file attribute information to the TSM
server, and the server stores the information in its database.

In a Lan Free/Storage Agent TSM 5.1 environment, which machine issues
the tape mount command to the robot:  the TSM server or the Storage
Agent?
