Hello everyone,

 

I woke up to my parity being disabled and one of the disks is missing. I am not sure what this is due to. Before I went to bed, it was working just fine and woke up to this. In the Identification field, I can see the HDD of the parity, but it's disables. Disk 3 says no device. Any help would be really appreciated.

Diags are after rebooting so not much to see, but since parity is disable see if you can get disk3 back, replace/swap cables and try again.

I've tried replacing and swapping the cables. Still same problem. I think it might be an issue with the Sata Port on the motherboard. When I replace it with a working HDD then it works. I just don't know how this would have happened.

swapping the cables.

Not clear by your answer if you swap cables does the problem follow the drive or stay with port/cable?

If I swap the cables then it follows the other drive yes.

So you need to get another board or controller and then re-sync parity, you can't rebuild the missing disk with parity disable.

Any suggestions on good controllers? I have a poweredge T410 desktop server. 

How many ports do you want/need?

I think 4 would be good enough.

Look for Asmedia 1064/1164 or the 5 port JMB585.

Thank you! Appreciate it all the help!
