Private LAN Dual Pathing

The private LAN on the VLS has dual pathing which consists of a cable from each switch to each
node. If a LAN switch or a path to a LAN switch fails, the data transfer will automatically fail-over
to the other available switch.
The primary path is through NIC 2 of the switch and is referred to in the error notification as
eth1. If the LAN switch associated with NIC2 fails, the Notifications tab will display all eth1
failures.
The secondary path is through the USB LAN cable and is identified as eth2 in the error
notification. If the LAN switch associated with the USB LAN cable fails, the Notifications tab
will display all eth2 failures.
If both paths fail, the critical alert will identify bond 0 as the combined failed path. If both
paths from the private LAN to a secondary node fails, the node is off-line; but if both paths to
a primary node fails, the whole device is off-line.
When a failure occurs, repair the failure. In most cases, the system will automatically recognize
that the repair is complete and restore the path or paths without having to reboot the system;
however, you may need to reboot the system if the repair includes installing a new USB LAN
adapter.
