Hey

So I have just moved my system to a Supermicro X10SRH-CLN4F with a 12 core cpu and it works great. Well I was angry yesterday, 3 of my 10tb harddrives did not show up in either unraid or bios. Had to tape over 3 pins on hdd  

 

My questions are

 

I moved all on my cache drives to the array because I installed 2 new cache drives and now I have moved it back to the new cache drives. But I still have System and Appdata left on the disk1. Can I just remove those without a issue? Maybe I did something wrong when moving them back? 

 

The motherboard forces me in to bios on every boot. Does anyone have the same board and know how to fix it? Kinda annoying to have a monitor plugged in all the time just to go out of bios. 

 

The fans are spinning up and down sometimes, why does it do it and is there a fix for it?

Unraid makes System and Appdata because it uses them, but if they also exist on Cache and they are empty, you can delete them. This probably happened if you started unraid with the drives, but the cache-drives weren't there yet.

 

There is no reason for it to go to BIOS every time, even if there is no OS there will be a message saying there isn't one, and it won't go to BIOS. See if the logs in IPMI show anything. You also don't need a monitor or keyboard attached, you can use IPMI to connect to it and control it remotely from a browser or IPMIview.

 

If the fans are spinning up and down just sometimes it's because of heat, and normal. If they spin up and down all the time, you may be using fans that spin too slow for the motherboard, and you'll have to alter the trigger-amount of RPM's. This can be done using ipmitool.
