   <em>
   For a multitude of (stupid) reasons, vendors often attempt to lock
   out our participation with their customers by refusing to give our
   programmers sufficient documentation so that we can properly support
   their devices.
   <p>
   Take Adaptec for instance.  Before the 3.7 release we disabled support
   for the
   <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=aac&sektion=4">aac(4)</a>
   Adaptec RAID driver because negotiations with the Adaptec had failed.
   They refused to give us documentation.  Without documentation, support
   for their controller had always been poor.  The driver had bugs (which
   affected some users more than others) which caused crashes, and of
   course there was no RAID management support.  Apparently most of these
   bugs are apparently because the Adaptec controllers have numerous buggy
   firmware issues which require careful workarounds; without documentation
   we cannot solve these issues.
   <p>
   The driver was written by an OpenBSD developer, who cribbed parts
   of it from a FreeBSD driver written by an ex-Adaptec employee.  But no
   public documentation exists, and Adaptec has dozens of cards with
   different firmware issues. All of this adds up to a very desperate
   development model -- it becomes very hard for the principle of
   "quality" to show its head.
   <p>
   RAID devices have two main qualities that people buy them for:
   <br>
   <ul>
   <li>Redundant
   <li>Repair
   </ul>
   You want a RAID unit to provide you with redundancy, so that if some drives
   fail your data is not lost.  But once a drive has failed, you require your
   array to (automatically, most likely) perform the operations that repair
   itself, so that it is functioning perfectly again.
   <p>
   Some vendors (or like the above Adaptec case, ex-employee) have
   sometimes given us some documentation so that we could write drivers,
   so that their devices could support Redundancy.  But these vendors have
   never given us any documentation for performing Repairs.
   <p>
   Instead these vendors have tried to pass out non-free RAID management
   tools.  These are typically gigantic Linux binaries, or some crazy thing, that
   is supposed to work through a bizzare interface in the device driver, which
   we are apparently supposed to write code for without any documentation.
   <p>
   And since we refuse to accept our users being forced into depending on
   vendor binaries, we have reverse engineered the management interface for
   the AMI controllers.
   <p>
   There is no great "intellectual property" in this stuff, it is all
   rather simple primitives.  This is all that we need to implement
   basic RAID management:
   <ul>
   <li>SCSI transactions on the back-side busses
   <li>Discovering which drives are in which volumes
   <li>Being able to silence the buzzer
   <li>Marking a new drive as a Hot-Spare
   </ul>
   <p>
   The AMI driver needed to support these small primitive operations.
   And once we had that, we rely on something else which we know: Almost
   all the RAID controllers would need the same primitives.
   <p>
   Thus armed, we were able to write a generic framework which would later
   work on other vendors' RAID cards, that is, once we get documentation
   or do some reverse engineering for their products.
   <p>
   But having been ignored for so long by these vendors, it is not clear when if
   ever we will get around to writing that support for Adaptec RAID
   controllers now.  And Adaptec has gone and bought ICP Vortex, which
   may mean we can never get documentation for the
   <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=gdt&sektion=4">gdt(4)</a>
   controllers.
   The "Open Source Friendly liar" IBM owns Mylex, and Mylex has told us we
   would not get documentation, either.
   3Ware has lied to us and our users so many times they make politicians
   look saintly.
   <p>
   Until other vendors give us documentation, if you want reliable RAID
   in OpenBSD, please buy
   <a href="http://www.lsilogic.com/products/megaraid/index.html">LSI/AMI</a>
   RAID cards.  And everything
   <a href="http://marc.theaimsgroup.com/?l=openbsd-misc&m=112630095818062&w=2">
   will just work</a>.
   <p>
   And keep pestering the other vendors.

   secure operating system,
   to communicate with the lost RAID. But alas, he is foiled once again by
   the evil Neozis.  Again he must chase the truth.  Will our hero prevail?<br>
