hwmond: Could not convert interface name

It’s funny how a generic error like this one is poorly referenced on google… “Could not convert interface name” returns no more than 8 results… None of them giving any hint on how to solve this issue. I guess Google’s not my friend anymore.

1. The log

2. Troubleshooting

The first result from google was giving some advice about checking wether the DNS is well configured or not. I always take extra care setting the DNS right, first for aesthetic reasons, then to avoid latency caused by the system trying to resolve the IP. But this time I forgot to setup LOM DNS. I created a PTR for 172.23.3.11 to node1.lom.xxxxxxxx.san, but it didn’t solve anything.

Second guess was to check what interface are used and might be monitored. After doing an ifconfig command, I realized that having an AJA card in the Xserve installed an unnecessary serial port in the Network pref pane. After cleaning to leave only public (eth0) and private (eth1) network, serialnumberd and fsmpm did reload (both related to Xsan), and my hwmond errors disappeared… Victory !!
