Hosts on an FC network

The host is the network server or PC that you wish to back up.
Library devices on the HP D2D cannot be created for a specific host during installation. When you create
a library using the Web Management interface you assign it to a FC port (port 1 or port 2) and the
library will then be visible on the FC SAN. When you log in, you log in to the switch to which the host
is connected, which means that the library is visible to all other devices on the SAN. You can zone
your network so that only specific devices have access to it, but generally it is visible to all. See also

Import/Export and Copy

If you attach a supported, physical tape drive directly to your HP D2D Backup System, you will be
able to copy or export data to the physical tape drive so that backups can be stored offsite. This is an
important requirement for Disaster Recovery strategies. The main difference between copy and export
is that copied data remains on the HP D2D Backup System; exported data is removed from it, but can
be imported easily when required. These functions are grouped under the Tape Attach section of the
Web Interface. Please see
details about working with Tape Attach.

iSCSI

On an Ethernet network the HP D2D Backup System is configured as an iSCSI device. This
means that the HP D2D Backup System plugs directly into the network, but it presents devices as
directly-attached SCSI autoloaders to host machines. In order to function, it requires an iSCSI initiator.
On Windows systems, this is normally downloaded by the Installation wizard, as described in
"Connecting and installing the HP D2D Backup
iSCSI, see "Advanced
Configuration Guide" on the HP StorageWorks Tape CD-ROM for more information.

Libraries

A tape library is also a backup device that has multiple drives and multiple storage slots. Each storage
slot contains a cartridge. The difference between an autoloader and a library is that a library can
