Hello from Australia
- the land of over priced PC hardware and few used Server parts ![]()
My new server build to learn TrueNAS and backup my media server is giving me grief. An exciting undertaking becoming a PITA.
A DOA motherboard and need to purchase a more expensive model once trapped into the AM5 line (couldn’t return CPU) meant sunk cost started kicking in :/.
I purchased all new hardware except the LSI HBA which is from a server reseller (I need to check the serial given my issues to see if its a clone).
Current hardware
- Asus x870 TUF AM5 motherboard (wifi, BT, Audio off, OC disabled).
- Ryzen 8600g CPU (I wanted the GPU given no IPMI, and ECC support)
- Kingston DDR5, 5200MHZ ECC UDIMM 2x16GB.
- Intel x550-T1 10GBe NIC (chipset PCIE Slot).
- Seagate Ironwolf 8TB x5 HDD’s (intend RAID6 or ZRAID2).
- SSD 250GB x2 for TrueNAS in RAID1. Connected with mb SATA.
- LSI 9305-16i HBA with 60mm Noctua fan fitted for cooling (CPU PCIE slot).
- PSU Thermaltake Gold 80, 550W which seems ok on jgreko’s list.
- Fractal Meshify case.
Two Computers are discussed - “Server” (being constructed) and “PC” (my desktop, which I use to flash and test the HBA).
I got the server hardware installed and tried installing TrueNAS Scale using current ISO to 2x 250GB SSD’s in RAID1 through install process… I discovered that things weren’t going ok with the HBA.
The LSI 9305-16i HBA will only recognise 2 of 5 HDD. I connected two SFF-8643 to SATA breakout cables for the 5 drives in my system and only 1 HDD on each channel is ‘seen’.
These are direct connect - no backplane.
Have you had this issue and do you know how I can correct it?
I put the HBA in my PC and updated firmware to 16.0.1.0 … the last Broadcom issued. I also installed the EFI bios (sas3mpt.rom).
I had to set HBA bios to “Legacy disabled” for it to show up at all in Server bios. Now it is seen in my server bios - but still not seeing drives.
I tried both server and PC with the HDD’s and HBA; Neither sees more than the 2 drives.
I disconnected 2 of 5 thinking it could be power but no change. Different sata power … no change.
Change sas cable channel on HBA, and the sata connector uses - no change.
I think it’s one of 3 issues:
- I need to reflash the bios to legacy from EFI for some reason.
- My sas cables are duds ($9 off amazon)
- The card is a dud.
The seller stated he tests them on a dell server. I don’t know if that means power on and see it’s in bios or connects drive array and confirms it actually functions. I’ve written to him to ask for more info and help.
The cables I’m returning to Amazon and have bought a different pair to check.
This forum is full of experts and I am hoping someone here can help me rule out something esoteric that is causing this in the instance it’s not an actual hardware fault.
As additional notes:
- Asus states their AM5 boards support ECC RAM (not just DDR5 “ecc”). My desktop is non ECC so I don’t think this is an issue.
- Until I disabled legacy bios with the EFI one installed the HBA would not show in the Asus TUF Bios or my TrueNAS dashboard.
Thanks for reading if you have - and my appreciation for any help or advice that comes my way ![]()
