So we have adaptors 0-3.
In this case it was on adaptor 2. Could loop through each adaptor.
$ sudo sas2ircu 2 DISPLAY | grep -B 9 -A 3 Z1F*****

So the disk is in enclosure 2, slot 6.
Adaptor = 2, Enclosure:Slot = 2:6
sudo sas2ircu 2 LOCATE 2:6 ON
Now physically locate the disk, the red LED to solid on. Don't pull it out yet as we can't turn the LED off without a disk in the bay.
sudo sas2ircu 2 LOCATE 2:6 OFF
Now pull the disk!
