G'day Guys,

I've just gotten my new Norco RPC 4224 and discovered when I plug in the SFF-8087 MiniSAS connector to my RAID controller, the backplane is backwards.

Normally, disks are numbered from left to right:

Row 1: 0,1,2,3
Row 2: 4,5,6,7
etc...

In this case, the drives are showing up as:
Row 1: 3,2,1,0
Row 2: 7,6,5,4
etc...

The only reason I discovered this was because I'm using a different sized disk for my system disks and they showed up as 2,3 instead of 0,1

I'm wondering if this could be the SAS cables I'm using?? Is it possible they are reversing my drive numbering? Has anyone else experienced this?
 
Yep, although the reverse breakout cable I have also has the same problem. The thing with this is I can "fix" the issue by plugging in the SATA ends in reverse as well :).

What's the deal with LSI?
 
You should try it with the HP SAS Expander, even more odd stuff going on with that setup...
One would expect big companies like LSI do actually validate their software(firmware/MSM/drivers), but even the craziest stuff slip through which makes one wonder...

You can try and file a bug-report with them, if they can figure the issue out it will take at least a quarter until you will see the fix.
 
hmm, that brings up a point. I`ll check the firmware revision of this card to make sure there`s nothing newer. Still doesn`t explain why the reverse breakout cable is also backwards.
