Hello, and thanks for taking the time to read this. I have attempted everything I could find on the internet and have exhausted everything I can short of throwing in the towel. I am going to include as much detail as possible. Sorry if the fix is simple but I just frankly am lost at the current moment.
I bought SAS drives (Seagate Exos 7E8) off of eBay, and the post claims they are working. My LSI card does not see them plugged into the card. My LSI card is LSI-9300-16i flashed to IT mode in version 16. The hard drives are plugged into a backplane from my server case which is a CX4712 from Sliger. Sliger claims they are using an SFF-8482 adaptor in the backplane. Sliger also claims that SAS-HDD is supported which, according to my research, should be working. Now I can confirm these drives are getting power since I can feel the vibrations from them (Maybe a better way than this?) so I don't think the PSU is the issue. The LSI card is being seen by BIOS and yes I was able to control c into that card and check everything out. The card is not see any devices plugged into it. In the office chance it matters, my motherboard is a SuperMicro x10dal-i and yes the PCI slot is working. It does not have SAS support so I could not test the drives by skipping the SAS controller. I was able to plug them into a Windows machine and it showed that the device did exist but since USB is Sata only, I could not make any changes to it. My running belief at the current point in time is that they are formatted badly but the seller claims the format is 512e which in my research should be fine I think. The sticker from the seller is Nist 800-88 clear and passed so I am unsure if that is making a difference. I have confirmed with a Sata Drive that the backplane is not the issue. The issue seems to be something with either the drives themselves or with the LSI SAS card.
In my head at least, This is the transaction for these hard drives
Seagate Exos -> SFF-8482 adaptor -> Mini SAS Cable -> LSI 9300-16i.
Kind of asking for any steps I should take to fix this. I am really close to either returning them or just ordering a SAS dock and going from there. Any kind of advice is appreciated. Ask me any kind of questions you think may be helpful! Thanks
