    Losing a Laptop

    A buddy recently checked into a hotel. He asked the desk clerk about in-room safes. He's told the hotel doesn't have them. Then he asked the clerk to recommend a good nearby restaurant within walking distance. He was given directions, went, ate, returned to his room, and found his laptop had been stolen. He wondered if the clerk was somehow in on the theft, but he couldn't prove it.

    A Hitch with SEA Failover Testing

    A few months back, I ran into an issue during shared Ethernet adapter (SEA) failover testing. After upgrading to VIO server 2.2.5.10, we would fail VIOS1 and verify our disks and networks were functioning as expected on the VIO clients. Then we'd bring VIOS1 back online and fail VIOS2. The network would hang on the VIO clients.
