Hi Peter, Have you tried powering the server off, unplugging it, then holding the power button down for 30 seconds? This will force the iDRAC hardware to restart, which is would be desirable, because the iDRAC also functions as the fan speed controller for the server.
Hi.  Had performance issues on the 5 year old PowerEdge T320 Server that turned out to be a Windows Hyper-V Issue.  I solved that issue.  However, as part of the troubleshooting process I ran the Pre-Boot Dell Utilities.  All tests passed, but the Fan Test caused the Rear Fan to be stuck on high.  I don't have an IDRAC License.  I don't have a Service Agreement.  Our plan was to retire the Server later this year, so I am trying to avoid purchasing a Service Agreement and/or IDRAC License.  I asked my Dell Account Manager if they could sell me something on the cheap since the issue was caused by running the Dell Diagnostics Tool, but the answer came back no. I have not updated the BIOS or the IDRAC Software or any other Dell Utility Software.  Perhaps that will help and I can do that for free.  Does anyone have any experience with this issue and if so, is it possible to fix without access the IDRAC Utility?   Also, I tried installing SpeedFan, but it did not recognize the server chipset.  SpeedFan detected the fan speed, but attempts to control the fan speed failed.  Is there a way to get SpeedFan or anther utility to work to lower the Fan Speed? Any other suggestions would be welcome. Peter at Cebic Technologies
