What I noted so far:

Yeah, they do get warm. Best to make sure you have a bit of airflow over
them. It doesn't take much air movement to keep temps in check.
- the disks were now in a different order, pretty much reverse order.
I am not sure the order will remain fixed (by port number?) or
variable (as the disks spin up).
The driver scans them in port/slot order, and apparently in order of
increasing pci address in the case of multiple cards. In my case where I
have staggered spinup enabled it spins them up in groups and then waits
for them in order, so things don't tend to move around unless you shift
hardware about or a drive fails.
Make sure you do a periodic lsdrv just for records sake, but as yet I've
not needed it. I keep a spreadsheet which lists which drive S/N is in
which physical slot so when something happens I can just look up which
drive needs to be popped without risk of pulling the wrong disk.
I swapped out a set of highpoint controllers for these LSI units back in
2011 and it was the best thing I ever did for storage speed and reliability.
