Okay, I guess I'm kind of necro-bumping an old post, but we have a customer who is getting lots of these cmnd_abort(1143) errors. They are using the old build 3278. Obviously, the Atlanta build uses a different iscsi target framework by default (it uses SCST vs. old IET). So, this will most likely fix the problem, right?

(Also, we're making the changes suggested in the knowledge base article regarding buffer lengths for the iscsi target.) We are also enabling disk write cache, which we've seen to GREATLY increase performance when using 7200rpm drives and the Areca 1680 controller (rebuild times decrease by a full order of magnitude).
