Hello! So I built a unRaid server on a SFF computer which only holds 2 HDD. I decided to add more HDD, I would build a JBOD. Before creating one, read to pretty much go with a SAS version. So I bought this PCI card for my server which already has it in IT mode.

 

LSI PCI Card - eBay

 

The JBOD is just a PC case, power supply, a SFF-8087 to SFF-8080 card, and a SFF-8087 to SATA cable. Links of what I assume could be relevant components.

 

Card

SAS to SATA cable

SFF-8088 to SFF-8088 cable

 

Add the WD HDD in the case, attached power and the SATA cables. Start the JBOD, start the server, and it only shows 1 of the 2 HDD. So seems all the components are working but not sure why it wont show the 2nd? I tried changing the power and SATA cables, no change. 

 

Sorry if I am missing anything. Decently new to server / JBOD etc items. Based the build above from many posts on Reddit data horders, unraid, etc.

That may not be the problem but note that without an expander and with SATA drives total cable length should not exceed 1M, you have 2M total.

 

If you swap cables for the disks does the other disk get detected or it's the same one?

So was the cables. Thought I had tried all the swaps, and always had one drive. Seems I didn't pay attention to the serial numbers of which drive was being found. So will return / order new cables, and get a shorter one while at it  

Thanks for your reply as it did lead to finding the mistake.
