The

Data Mover always uses the primary connection, if available. If the primary

connection fails, the Data Mover automatically switches to one of the standby

connections. When the primary is again available, the FSN automatically switches

back to the primary connection. This is desirable if the primary device is a higher

speed connection or if you prefer a particular device. However, if the primary device

becomes unstable, automatically switching back to it might cause the FSN to toggle

between the primary device and the standby device.

When a port in an FSN device fails, an operational standby device in the same

FSN device on the same Data Mover takes over:

• No primary device specified: The FSN continues using the secondary

connection until it fails.

• Primary device specified: The FSN automatically switches back to the

primary connection when the primary is available again. This configuration

can cause a toggle effect if the primary device has intermittent link loss.

Hope this helps,
