Connecting to the network

If you cannot access the StoreOnce target 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.
2. Check that the LEDs are flashing on the LAN Port. (See also
If no LEDs are flashing, there is no network connection – check the Ethernet cable or
consult your network administrator.
If LEDs are flashing, check that you have the correct IP address for your HP StoreOnce
Backup system. Are you using DHCP or Static IP addressing for your HP StoreOnce Backup
system? If you are unsure of your settings, please login to the local console and use the
StoreOnce CLI command:
# net show status all
3. Use the StoreOnce CLI command, net ping, to check that you can ping another network IP
in the configured subnet. Ping a known IP address in each configured subnet and also check
that you can ping the StoreOnce system from another system in that same subnet to check that
ping works in both directions. If it fails, check the network configuration on the StoreOnce
system is correct for the subnet. Also, check that the subnet is working correctly by ping testing
between other systems in the subnet experiencing an issue.
A StoreOnce CLI command, system confidencecheck externalNetwork, is available
to test all of the external network connections. Any warnings or errors should be rectified.
4. Is your network running IPv4 or IPv6 mode?
Ensure that you have selected the correct IP Address for the network you are using.
5. Is backup running across a Virtual LAN?
VLAN tagging is supported, but must be enabled on the Port Set and configured correctly.
Make sure that the correct VLAN tag IDs for each VLAN subnet have been configured
during configuration.
You can check the configuration of VLAN tag IDs using the StoreOnce GUI (Device
Configuration - Network Configuration - Current) or using the StoreOnce CLI command, net
show config current.
6. Is the StoreOnce appliance configured for network bonding mode 4, where LACP is used. If
this is the case, both the StoreOnce appliance and network switch must be configured for
