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 IP addresses for the virtual interfaces? There will be a Cluster
Management IP address for the Management Console and a Data VIF IP address for each
node on the cluster. You use the Cluster Management IP address to access the StoreOnce GUI
and CLI, and the Data Path VIFs to configure backup from NAS shares and replication.
•
Were the gateways configured correctly at installation? Review the information provided by
the HP service engineer after installation.
•
Was the correct bonding mode selected for your network configuration?
Network bonding modes
Three bonding modes are supported:
•
Mode 1 (Active/Backup)
This is the most simple bonding mode; it allows network traffic via one active port only and
requires no specific extra switch configuration. It is recommended for simple network
connections.
•
Mode 4 (IEEE 802.3ad Dynamic Link Aggregation)
This bonding mode is also known as LACP and requires a special external switch configuration.
It provides a link aggregation solution, increasing the bond physical bandwidth but can only
work if all the ports in the bond are connected to one switch. It is recommended when :
◦ The customer wants to increase throughput to the StoreOnce appliance
◦ Trunks between switches on the customer network already use LACP mode
The LACP protocol only works when it is configured on both ends of the physical connection.
•
Mode 6 (Active Load Balancing)
This mode provides a load balance solution. It does not require specific external switch
configuration, but does require the switch to allow ARP negotiation. It can be used in a 2–switch
configuration.
