You've Installed Dell PERC RAID, But the Controller Can't See and Use the Installed Hard Drives!
This issue can cause support workers to grow a lot of gray hairs. Everything might look perfect, but for some reason, it’s not working. When you boot the server, there doesn’t seem to be a problem – until the disks don’t spin and there are no indicator lights to be seen.
How can you avoid this headache? Check the carrier frames. Make sure the hard drive is in place properly. If there’s no connection between the hard drive and the backplane, there might as well be no hard drive.
