Connecting to the HP StoreOnce Backup System from the backup
application
Make sure you have the latest version or software patches for the backup application. Please see
http://www.hp.com/go/connect
Stop and restart the backup application services after the backup device has been discovered. If
you still cannot access the device, check Device Manager to make sure it is accessible from the
host.
Make sure that the iSCSI initiator is connected to the devices and log on to them, if they are
not, see
If it is not accessible, rerun Discovery.
NOTE: There are practical limitations on the number of devices that each host and FC switch or
HBA can access. It is possible to configure more drive and library devices than a host can access.
See the D2D Best Practices for VTL, NAS and Replication implementations for maximum and
recommended values.
Connecting to the network
NOTE: If you have selected the Link aggregation mode, ensure that switch is configured correctly
at the other end.
If you cannot access your device on the network, please check the following:
1. Regardless of the network configuration mode and interface type, please ensure that there is
a CAT-5E (or above) Ethernet cable connected to network port 1 (HP D2D4100 Series and
HP D2D2500 Series) or network port 3 (HP D2D4300 Series). This is the primary port for
communication to the Web Management Interface and, on SCSI models, the primary port for
