Alright, so I am apparently a gigantic moron. While I have been building PC's and servers for 20 years, I did not know that SATA power cables are not interchangeable between different PSU manufacturers. They will sometimes fit PSU's by different manufacturers because the connector is shared between some of them but for some reason the pinout of the PSU is not standardized and most manufacturers use a different one, sometimes even between different PSU models by the same manufacturer. So, I apparently blew up 4 x 12TB drives, ouch I noticed indeed that they didn't even appear in the BIOS when connected to onboard SATA. These were WD shucked drives so initially I thought that the 3.3V pin would need to be covered, even though that shouldn't be needed anymore with newer WD drives. When that also didn't work even after removing the pin altogether, I went looking further and encountered someone that had blown up a drive because he used a SATA power cable from another manufacturer. This made me check and surprise, surprise, one of the cables was not like the others and it was the cable I had used to connect these new drives. How that cable got mixed in with the rest I do not know, but it is a Seasonic one while this particular PSU is a Corsair one. So yeah, this was a grave ID10T user error I'm going to leave this up so someone else might learn from my mistake. Never, ever use power cables on a PSU that did not come with that specific PSU. Lesson learned, even though it was a very expensive lesson, it will make sure I never make that mistake again

Hello I know this is an unsupported setup but I'm hoping someone can shed some light on the issue I'm experiencing. I have unRAID set up in ESXi. The general system works well. I boot directly off of the USB drive, so no PLOP boot manager, simple USB passthrough. I have also passed through my PCI NIC, which works since I can access my setup, so PCI passthrough seems to be working as far as NIC's go I have an LSI 9211-8i, bought with IT-mode enabled from a vendor that only sells IT-mode HBA's and is very popular. I have passed this through to the unRAID VM as well and the controller is seen by unRAID and properly identified, it is visible in the system devices menu and I am even able to trigger passthrough to an unRAID VM, though I of course don't want that. However, my disks don't appear to be detected. I have searched for hours but since I'm very new to unRAID, I struggle to find the proper logs to comb through in search of a cause. The disks are spun up (you can feel this) and I have replaced the breakout cable already to rule that out. The cables I'm using are the proper SAS->SATA breakout cables. I have also tried swapping to the second port on the controller I'm hoping someone here can take a look at my diagnostic bundle and shed some light. If more information is needed I will of course provide it. Diagnostic bundle attached Thanks in advance! *edit* As you can probably see in the diagnostic bundle, I am currently running a trial license. I have already bought a real license but decided I would first make sure this setup is stable before I activated that. I assume the functionality is identical between the two, so this should not be a factor in this issue *edit 2* I have verified in the BIOS that the HBA is set to IT-mode and is properly recognized unraidserver-diagnostics-20230101-1412.zip

That's awesome, that means I can already get started, sweet. Also very good to know that you have actually done this in the past, that is a much better answer than "it's theoretically possible". This is great. I had indeed not expected this to be possible. It's quite impressive that it actually is, as most (enterprise) storage solutions are very finicky about things like UUIDs and migrations to dissimilar environments, protocols or hardware Thank you very much for confirming this and for the offer of guidance. If I have any doubts at all during the migration procedure I will reach out for sure, better safe than sorry (though I do have off-site backups, of course) I'll also go through the forum to see if I can find any information on this. I've already tried searching briefly but I have to admit that I only did a very quick sweep before posting here, it's very likely that I missed whatever information is out there Cheers and thanks again!

Hello everyone I have quite a simple question, at least I think it's simple but I might be mistaken. I am planning on virtualizing unRAID using ESXi. Now, I have already spent waaaaaaay too much money this month on a new server, storage, parts,... because of course I did 😂 I don't yet have an LSI HBA to do PCI passthrough with and it's not in the budget anymore this month. I am however very eager to get started, so my question is: if I set up unRAID on ESXi using RDM disks, so passing through my disks connected to the onboard motherboard SATA connecters to the VM, can I then later when I have bought an LSI HBA, migrate my disks to PCI HBA passthrough without having to wipe my data? In other words, can unRAID volumes be migrated transparently from one passthrough method to another? I suspect this will not be possible because the UUID of the drives will change but I am looking for confirmation Thanks in advance! Cheers
