I've done a bit of lurking and I believe I am ready to install an add on 24 disk shelf to my FAS2240-2 system. I was wondering if you could take a look over my procedure and let me know if it checks out. I really appreciate it.
Things to consider: our current setup is 2 aggregates(1 on each controller) with 11 disks split between them in raid DP ( 2 spares)
I am adding an additional 24 disks and wish to make a new raid group in each aggregate.
all disks are 600gb SAS
6. After confirming disks are seen by the controllers they will now be split between both:
Controller1: disk assign 1,3,5,7,9,11,13,15,17,19,21,23
Controller2: disk assign 2,4,6,8,10,12,14,16,18,20,22,24
7. Create new raid groups on existing aggregates(2) with the following commands
aggr add aggr_1 -g new 11
aggr add aggr_2 -g new 11
(we don’t assign 12 as I’d like to keep a hot spare disk per raid group)
reallocate -f -p /vol/ vol_1
9. Turn back on auto assign
Solved! SEE THE SOLUTION

Yes the existing raid group is actually the default at 16 but there are only 11 disks. Rather than add 5 disks I decided to just make a new raid group.

ACP and SAS cabling are fine.
But he is correct in the sense that NetApp best practice recommends you go IN to a square port and OUT of a circle port. Easy way to remember is 'O' for OUT. Doesn't matter if you have it backwards as long as its consistent across the environment, but Config Advisor will identify the discrepancy between circle and square and alert accordingly. Functionality is the same.
