Figure 2 Device configura tion wit h one host
• By default, the host sees only one device, the autoloader that has been configu red for it during
installation. Data from each h ost goes to its corresponding autoloader.
• Each backup device is visible only to the host for which it has been con figured.
• A host may have multiple devices config ured for it on the HP D2D Backup System, but this means
fewer hosts may be connected (not illustrated, see Figure 34 on page 61 for an example of
one host with t wo devices).
