Back in the z890 days, we had a CPU fail. Of course, the hardware automatically recovered and we only knew about it due to a logrec record being written and a message on the HMC. We also had one of our OSAs fail. The second OSA did an ARP takeover (proper term?) and we suffered _no_ user interruption. The LAN people _refused_ to believe that the OSA could fail that way without disrupting all the IP sessions of the users on that OSA. Apparently when a multi-NIC PC has a NIC fail, all the IP sessions on that NIC die immediately (well, they time out).
