The following is a fail-back procedure, describing how to recover from the cluster switching.

1) Recovering the node, which encountered a failure

If switching was caused by panic or hang up, then reboot the node.
On the other hand, if switching was caused by a transfer path failure, then recover the transfer path encountered a failure. (Recovering options are reconnecting the cable, restore the power of HUB, and exchange the broken HUB.)

2) Fail-back to an arbitrary node on standby
