FreeBSD 6.0 compat with DL320 G4

Let me ask you this:

  Would you, right now, feel comfortable walking into your server room
yanking out one of the SATA drives?  Then shut down the server, install
drive back in, and initiate the rebuild?

  I have done just that to our production Compaqs with SCSI arrays on
the intelligent controller, of course I don't have to down the server to
the array since the controller does it automatically when you put the
back in.  It is one of the most effective sales tools we have, we've sold
several servers by doing this.

  I would also feel comfortable doing it to a server running the 3ware
raid card.

  I don't know I'd feel comfortable with doing this with raidctl but I
are going to end up testing this out since that's probably what we are
going to
have to end up doing with ours, at least until Soren reverse engineers
the Adaptec
metadata format for some future version of FreeBSD.

  But if I had known about this problem in advance I would never have
the server.
