OH MY GOSH aos saving me again
watch this video, solved my problem:
Summary:
1. Get lsiutil (good samaritan hosted here: https://github.com/thomaslovell/LSIUtil/), (and save to unraid)
2. ./lsiutil -s to show all devices
If you see "SAS2308's links are off, off, off, off, off, off, off, off", keep going! (this is bad)
3. select your device with ./lsutil -p 2 -e (mine is on port 2, my internal card is port 1)
4. 68 shows port state summary, look for these problematic settings:
"port stat off,off,off" (bad, as above)
Link Enabled: No (bad)
SSP Target Enabled: No (bad)
5. 61 sets default values, then 68 to view port state again. this enables the links, but port state will still show "off,off,off" because you need to reset to take effect
6. 99 to reset the chip, then 68 to check that ports with plugs in em say "6.0 G" (connection speed) and if disconnected say "down" -- not "off"!
Once I did this, my plugged-in drives immediately appeared in UD!
