Managed System for SAN Storage Agent User's Guide
The following outlines a typical backup scenario for a TSM client that uses
SAN data movement.
- 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.
- 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.
- The server contacts the storage device and mounts the appropriate
media.
- The server notifies the client of the location where the mounted media
resides.
- The client, by means of the storage agent, writes the backup data directly
to the device over the SAN.
- The storage agent sends file attribute information to the TSM server, and
the server stores the information in its database.
