I have seen this being reported by others as well. With the mpt driver, they show up in the right order, though. Any ideas what might be causing this?

The ordering is not guaranteed and, since SunOS 5.0, not expected. When you
use SAS devices, you'll see the "ordering" look more like the SAS address.

Make sure you run as root or with appropriate privilege. Running fmtopo as a
unprivileged user won't show disk details.
