NOTE: Physical tape storage devices attached to the HP D2D Backup System can only be accessed by the HP D2D Backup System using the Tape Attach pages. They do not appear as attached network devices to the host system. Seeding Virtual Tape Devices using Tape Attach Use the Library or Tape Attach Copy functionality to create a physical cartridge that can be shipped to the site of the Target Appliance and imported. You only need to seed with one full backup. 1. Host backs up to a Non Replicating library on the Source Appliance. 2. The first full backup is copied to a cartridge on a Tape Library. 3. The physical cartridge is shipped to the Data Center. 4. The first full backup is imported from Tape Library into a Non-Replicating Library on the Target Appliance. It is also possible to import the cartridge into an unmapped slot of an existing Replication-Target library. 5. Once imported create the replication linkage between Source and Target Appliances and configure slot mappings. 6. Normal replication across the WAN can now take place with only new or changed data needing to be replicated. NOTE: When recovering data after a disaster has occurred in the remote site resulting in the loss of both the host servers and the D2D system, you can speed up data recovery to the D2D by using the last full backup cartridge to reverse seed the Virtual Tape Library. Configuration (Tape Attach) This page allows you to view physical tape storage devices that are attached to the HP D2D Backup System. The top half of the page shows a list of configured physical tape devices. NOTE: With a SCSI interface, up to two tape drives may be connected (including tape drives in libraries), and up to two tape operations (import, export or copy) from separate libraries may take place at any one time. With a SAS interface, up to four tape drives may be connected (including tape drives in libraries), and up to four tape operations (import, export or copy) from separate libraries may take place at any one time. NOTE: Standard HP Ultrium barcodes should be applied to all cartridges in libraries to ensure correct media type identification. Backup System user guide 185

Physical tape storage devices attached to the HP D2D Backup System can only be accessed by the

to the host system.
Seeding Virtual Tape Devices using Tape Attach
Use the Library or Tape Attach Copy functionality to create a physical cartridge that can be shipped
to the site of the Target Appliance and imported. You only need to seed with one full backup.
1.
Host backs up to a Non Replicating library on the Source Appliance.
2.
The first full backup is copied to a cartridge on a Tape Library.
3.
The physical cartridge is shipped to the Data Center.
4.
The first full backup is imported from Tape Library into a Non-Replicating Library on the Target
Appliance. It is also possible to import the cartridge into an unmapped slot of an existing
Replication-Target library.
5.
Once imported create the replication linkage between Source and Target Appliances and configure
slot mappings.
6.
Normal replication across the WAN can now take place with only new or changed data needing
to be replicated.
NOTE:
When recovering data after a disaster has occurred in the remote site resulting in the loss of both the
host servers and the D2D system, you can speed up data recovery to the D2D by using the last full
backup cartridge to reverse seed the Virtual Tape Library.
Configuration (Tape Attach)
This page allows you to view physical tape storage devices that are attached to the HP D2D Backup
System. The top half of the page shows a list of configured physical tape devices.
NOTE:
With a SCSI interface, up to two tape drives may be connected (including tape drives in libraries),
and up to two tape operations (import, export or copy) from separate libraries may take place at any
one time. With a SAS interface, up to four tape drives may be connected (including tape drives in
libraries), and up to four tape operations (import, export or copy) from separate libraries may take
place at any one time.
NOTE:
Standard HP Ultrium barcodes should be applied to all cartridges in libraries to ensure correct media
type identification.
