Further info: The affected node 2379's URI is off but the other URI on the other node 2416 was still on and flashing. If the Bios and/or Centos is shutting off the USB port then why doesn't it shut off the other node too? I have other boxes with single nodes that this never happens. I have built 2 other boxes with 3 nodes and 4 nodes, all of which are using URIs and this doesn't seem to happen. I thought I went through all the bios settings to make sure nothing goes to sleep. This has happened on 2 different pcs with a dual node config. Jon The URI appears to be off with no lights on when this happens. On 9/19/2010 10:03 AM, Ken wrote:
This sounds like a case where the BIOS (or CENTOS?) decides to shut off the USB port for power management reasons after seeing no data for an extended period of time ... does the green light just stop blinking or go out altogether? Maybe you could program the links to send some silence or something every 5 minutes and see if that keeps it alive... as an experiment.
