Disconnecting hosts
All hosts on which the Installation wizard has been run are automatically reconnected to their device(s)
when the HP D2D Backup System is restarted. If you want to disconnect a host permanently, you must:
•
Use the iSCSI Initiator to deselect Persistent Target, log off the target and remove the IP address,
see “
” on page 45. If you do not do this, the host will continuously try to
reconnect, which may slow down the system.
•
Use the Web Management Interface to edit the target information for the device that was
connected to the host. You may want to make it accessible to a different host or delete it. See
Device troubleshooting

•
Check that you have entered the correct IP address for the HP D2D Backup System in the host’s
browser.
•
Make sure that the host and the HP D2D Backup System are still connected to a working network.
• On the HP D2D Backup System, check the LEDs. The Network LED on the front of the HP D2D
Backup System will be off, if there is no network connection or the network has not been
configured. The LEDs on the network connector on the back of the HP D2D Backup System will
also be off if there is no network connection.
• From the host, see if you can connect to another internet address.
•
Make sure that the host is on the same subnet as the HP D2D Backup System.
•
Try connecting from another host on the same network.
•
Try to PING the IP address of the HP D2D Backup System. If PING is successful, there is network
communication between the host and the HP D2D. If PING is unsuccessful, troubleshoot the
network and network settings.
If you still cannot see the HP D2D Backup System, use the standalone Discovery tool. Discovery is run
as part of the Installation wizard; it is also installed as a standalone utility on your desktop. Run the
Discovery tool and check that the HP D2D Backup System appears in the list of devices for selection.
Use the Beacon option to identify a particular HP D2D Backup System on the network.
If Discovery cannot find the device, check whether there is a Firewall. You may need to temporarily
disable it. It can be re-enabled as soon as the device is configured. Or, the HP D2D Backup System
may be on a different subnet. If possible, connect the HP D2D Backup System directly to the host. If this
fails, contact HP Support

.
Backup application fails to see device
Make sure you have the latest version or software patches for the backup application. (See
www.hp.com/go/connect
) Stop and restart the backup application services after the backup device
has been discovered.
If you still cannot see the device, check Device Manager to make sure it is accessible from the host.
