Yes, you can do this. And the sim isn't showing a bug, that's what
ONTAP would do. It's just not a good
idea to mix drive sizes within the same RAID group. You're begging for
performance issues if you do so.

Subject: Same aggregate, different size disks?
Is it possible to have both 144G and 300G disks in the same aggregate,
but different raid groups? I can't seem to find any documentation on
this.
I tried using the ONTAP Simulator to test this, but the simulator seems
to have a bug because I was able to add disks of multiple differing
sizes to the same raid group (without right sizing them to a common
size) and I was even able to add a smaller disk to a raid group of
larger disks.
