NOTE: If the Discovery process does not find your appliance and you are accessing through a
firewall, you may need to temporarily disable the firewall or open UDP ports 8105 and 8106 and
retry.
Beacon mode
The HP StoreOnce Backup System supports a Beacon LED sequence, which helps a user identify
which unit is being configured, if several are connected to the network. See also Understanding
LEDs.
If the HP StoreOnce Backup System is new and not yet configured
When installing the HP StoreOnce Backup System for the first time, this step must be completed
successfully before you can connect from your host. Select the appropriate HP StoreOnce Backup
System from the list and make a note of its IP address because you will need this when you configure
the iSCSI Initiator, see also Discovery tab.
If the HP StoreOnce Backup System has been configured incorrectly
If you cannot connect to the HP StoreOnce Backup System using the Web Management interface,
it may have been configured incorrectly. Run the Discovery Engine to check the IP address of the
HP StoreOnce Backup System and, if necessary, select it again from the list of available HP
StoreOnce Backup Systems. If you still cannot connect to it, check that you have configured the
iSCSI Initiator correctly, see also Discovery tab.
If the network setup has been changed
If the network infrastructure changes, you may need to update the HP StoreOnce Backup System
network settings to allow hosts to continue to connect. Run the Discovery Engine and change the
network settings in accordance with your new infrastructure.
You can also use the Web Management Interface to modify these settings directly on the HP
StoreOnce Backup System, as long as this is done before the infrastructure changes are made.
Once the network settings of the HP StoreOnce Backup System have been changed, you must also
change the iSCSI Initiator for each host.
