The main issue with the cables is that they must be forward breakout cables, reverse breakout look the same but won't work for this, but like I mentioned and unless I saw wrong in the first diags it was detecting a drive, that would mean the cables are the correct type, can you confirm if there was a 2TB Seagate Firecuda connected to it?
The HBA itself appears to be working correctly, it's detected and initialized without errors, of course if there's some issue with the connections that won't be visible in the logs.
