I have been battling this for about a week now and am at my wits end.
I had DSM 6.2 installed on the Chenbro NR12000 but would like to install DSM 7.1 if possible due it being somewhat exposed to the internet and what not. Whelp, the issue I have now is that while using TCRP M-Shell and other TCRP loaders, when I do the sataportmap command it wants to map the 6x sata drives that are on the board, and while is displays the sas controller and that a disk is present, it completely ignores such, and any disks on connected to such are not shown. I have messed around with the sataportmap'ing and have been unsuccessful so far getting the SAS controller to present any disks to DSM. Anyone have any experience with such?
