Previously used array HDD not showing up

[idwxyz]

I initially had an array of 4x4TB drives (1 for parity) with a 2x1Tb cache pool. I have gradually replaced all of the 4TB drives with 12Tb ones. 
 

I would like to use one of the 4TB ones as a dedicated drive for a VM but unRAID doesn’t seem to see it. 
 

My motherboard has 8 SATA connections 6 are taken up with the array and cache drives. I plugged two of the 4TB drives into the last two sata ports but they don’t show in the UnRAID interface. 
 

Do they need formatting on another machine first?

Are they seen by the servers BIOS?

 

you should post your system’s diagnostics zip file (obtained via Tools -> Diagnostics) attached to your next post to get more informed feedback.

Here's the diagnostics zip file. Good point to check the BIOS. Unfortunatly I'll need to hook up a monitor to check the BIOS, I'll have to try it once I can get my daughter to sleep.

You have a USB device ‘spamming’ your syslog which makes it difficult to look for errors - if possible remove it.

 

as far as I can there is only the one SATA controller showing up at the hardware level.   You probably need to check in your BIOS settings that the controller for the additional 2 SATA ports is actually enabled.

You were completely right. I had to enable the ports as it shares PCIe lanes with one of the PCIe connectors. It's now working as expected and as a bonus I was able to enable virtulisation as I didn't realise that was disabled by default.

 

Thanks.
