I had two disks disk 1 and 9. Disappear at first I thought was bad disk. But no matter the switch of disks they wont show up. I bought 2 new disks and they wont show up either. MY sas card can do 8 HDDs but it only shows 3 and I swapped sas card for another and still same effect.

 

I had a weak gpu on pci 1 and decent gpu on pci 2 and my sas on pci 3. I thought it was not getting enough bus speed so I removed 1st gpu. But still same effect. You would think at least the 4th hdd would show up on the sas ? I have bunch of y spliters powering the drives.

See if the drives show up in the LSI BIOS, also good idea to update its firmware.

Sorry for late reply , I been out of my mojo. I turned on and had monitor plugged. Noticed new screen to show the SAS drive bios boot. Like usually it would show  all drives it has and reboot to the bios right? Thats not happening. the card I have in now is a NEW USED HP SAS card. I have a LSI and that one was updated long ago. It worked with other drives before.

Don't quite understand what you mean, during boot you should see the LSI BIOS and it will list all the devices detected, check if the SAS drive is listed there.

Its not there in bios , I remember back with my other LSI card that when you booted it was this order MOBO BIOS -> LSI BIOS -> MOBO BIOS 

 

now its just MOBO bios. Unraid detects 3/8 drives connected to the SAS card. I have 2 SAS cards both are same deal.

Make sure CSM boot is enable in the board BIOS, LSI BIOS won't show up with UEFI boot, HBA has a BIOS flashed so it should appear if booting CSM.

CSM is enabled from the get go but no bios screen.

Both cards wont show up on the bios. So the card used to work. My mobo ethernet crapped out , is it possible the mobo has failed.
