I recently tried to create a brand new unraid server and I can't figure out why none of my hard drives are showing up... 

 

Motherboard is a Gigabyte ga-z170x-gaming 3

Controller: IBM M5110 6Gbs PCI-E HBA FW: P20( LSI 9207-8i IT) This exact one

Expander: Intel RAID Storage Expander RES2SV240 E91267-203 This exact one

 

I have 15 16 hard drives connected..i touched a few of them and they seem to be running...

I also have a few SATA HDDs connected to the on board SATA ports and those aren't showing up in Unraid either in case that matters..

Update: I was trying to use my PCI E 16x (usually for graphics card) and it wasn't providing any power in that slot (my graphics card died in that slot previously) and I didn't notice.

 

Moving it down 1 pci slot got the HBA working, but I only see 4 drives instead of the 16 I have connected..

 

Here is more info:

• Controller: IBM M5110 6Gbs PCI-E HBA FW: P20( LSI 9207-8i IT)
  • Two SFF-8087 to SATA Forward Breakout cables connected to 8 drives
  • The four drives that Unraid sees is from one of these cables on this controller.
• Expander: Intel RAID Storage Expander RES2SV240 E91267-203
  • Two of the same cables connected to 8 more drives
  • I don't think the system sees the expander. 
• Hard Drives: Some of the ones not showing up are Western Digital external backup drives that I shucked. Would the extra power pin that people sometimes have to tape over/remove need to be removed from the drives not showing up?

removing the 3.3 pin from one of the western digital drives turned it on, but I think my expander isn't working.

 

Is there a way for me to tell if it's being detected or on?

I think i misread the expander being "plug in play" in other posts and didn't realize it needed a mini sas connection to the controller.. I ordered one and this will probably solve my issues. If it does, I'll come back here and mark this thread "solved"

 

Thanks for all those who came to read this thread and sorry for probably wasting your time.

No expander have detect, check the power , SAS cable, LED status, and touch heatsink warm or not.

 

EDIT: You got no SAS cable between controller.

if the PCIe card has died, it may have taken out other components on the motherboard that may be causing the issue you are seeing. new motherboard?

You can connect the expander to this controller then connect all disks to the expander.

Confirmed it was my idiocy and was missing the cable between the expander and controller. Thanks everyone!
