Been using SoftRaid XT for some time without issue, currently on 7.5. On a Mac Mini, osx Monterey 12.7.6, running a ThunderBay 6 on RAID 5 over Thunderbolt.
Friday evening I was switching my monitor Thunderbolt cable from a work laptop back to my Mini, and I must have nudged the Thunderbolt cable that connects the ThunderBay 6 as the time from the log below matches up. The Mini’s system had been sleeping for quite some time and did not respond, stayed in it’s sleep state.
When waking the Mini later that evening I got a warning from SoftRaid that “Disk for SoftRaid Volume has disappeared”. The Raid volume was not on my desktop and upon opening the SoftRaid application, none of the disks nor the volume appeared.
After restarting and trying a new Thunderbolt cable, none of the disks nor the volume appear in SoftRaid, nor in Disk First Aid. Any help or advice would be appreciated, I’m pretty experienced on a Mac but have only limited experience with Raid and haven’t yet been through a rebuild process.

I should add that after restarting, I turned off sleep in the Energy Saver prefs pane.
And I attempted to attached my SoftRAID Tech Support file here but got a message saying filetype is not supported (wtf?) ExampleFile.sr_supt
We have to fix this attachment issue. I don't know what caused that.
Did you power cycle your drives?
No worries regarding the attachment issue.
Drives have been power-cycled a few times with no change. LED light showing orange.
Either you have a failed cable, computer (thunderbolt port) or enclosure. Most likely cable, so move things around. This is 100% a hardware issue
Appreciate you narrowing it down. I've switched ports at both computer and enclosure sides, and 3 different cables. All the same, no change, no result.
This would leave me to believe that the only non-working element is on the enclosure side. Do you know if OWC has any replacement Thunderbolt controllers (or whatever it is) that I could purchase?
How old is the enclosure? I am not in hardware, but can check... Is this a thunderbolt 2? 4 bay?
Thanks for getting back to me so quick and appreciate you checking...
It's a ThunderBay 6 with Dual Thunderbolt 3 Ports. Purchased in January 2019
Thats been discontinued for a while. We may not have spare parts, as it was the only 6 bay we did. I will ask on Monday.
Thank you for that, much appreciated! Sorry to interfere with your Sunday...
There are no spare parts left sorry. I did check ebay and not much there. A replacement might have to be the 8 bay.
Are you able to provide me with a part number or a specific description to search for? I'm not sure if I can afford to upgrade at the moment...
And would you have any insights on how to crack the Thunderbay case? She's pretty solidly put together.
At least on ebay, you cannot search by part number, they are not there. Generally it is the Thunderbay 6-bay, but you will get all kinds of 4 and 8 bay results. Ebay had one,but full of drives and expensive (over $1,000)
The screws are on the bottom, inside the rubber feet. I believe the bottom of the feet can be removed, giving access to the screws
Thank you! I've been able to crack the case and isolate the TBT3 controller. Haven't had any luck finding a replacement so far but I'll keep looking.
Any idea if I could replace it with a similar, but not identical one? I may have to task a local tech guy to confirm the failure hands on and look into repair/replace options... Any insights you could provide into this would be valuable to me and thank again for your help so far :)
I have no idea here, you are in uncharted waters!
this enclosure has 3 PCI lanes, and a NVMe slot. But I cannot guess to how to replace/repair any components.
