Apple System report shows it's connected to the thunderbolt

All lights on R8 is

Promise (ver 4.06) utility can't see the R8 as well.

Running intel macos monterey 12.0.1

Hi Shing,

It looks like the driver is not loaded. Please run the following commands from a terminal.

promise@promises-Mac-Pro ~ % sudo kextload /System/Library/Extensions/PromiseSTEX.kext
Password:
Executing: /usr/bin/kmutil load -p /System/Library/Extensions/PromiseSTEX.kext
promise@promises-Mac-Pro ~ %

This will manually load the driver. Then verify that it's loaded with kextstat.

promise@promises-Mac-Pro ~ % kextstat | grep -i stex
Executing: /usr/bin/kmutil showloaded
No variant specified, falling back to release
   70    0 0xffffff8003434000 0xb000     0xb000     com.promise.driver.stex (6.2.13) AE253556-66D8-38D2-B9D1-179B78F29153 <69 16 7 6 3>
promise@promises-Mac-Pro ~ %

This shows the driver is loaded. If the volume does not mount unplug and replug the thundebolt cable.
