Reserved IP address
The HP StoreOnce Backup System uses the 10.154.x.x ip range for its internal network. This means
that this IP address range is not available for the customer's network. It may cause conflict and
unpredictable results if a customer network uses the 10.154.x.x ip range.
Problems connecting from the network
The HP service specialist documents the network configuration for you at installation. If you
experience problems connecting from your network, check the initial configuration documentation.
• Are you using the correct VIF addresses? There will be one VIF address for the Management
Console and two data path VIF addresses for each node on the cluster. You use the
Management Console VIF to access the GUI and CLI, and the Data Path VIFs to configure
backup from NAS shares and replication.
• Which template did you use? Templates 1 and 4 support two subnets, so you can have
management and data path access on separate subnets. However, only one gateway is
supported. For example, If the gateway is on the data path subnet, you will not be able to
access the management functions remotely.
Network troubleshooting and failover
Always disable failover before troubleshooting network connections or unplugging network cables
on the back of a node.

IP addresses and couplet/rack expansipn
As long as the recommended number of IP addresses is allocated during the network configuration
process, the B6000 Backup System will automatically assign IP and VIF addresses for all possible
nodes in the system when the network is initially configured. This means that it will assign enough
IP and VIF addresses to cater for any additional couplets that may subsequently be added.
If you do not supply the recommended number and subsequently expand your system, you will
need to reconfigure the network. More importantly, you will also need to reconfigure the addresses
used for backup and replication targets.
