I forgot to bundle the DM config file with the 2.2-stable snapshot. Sorry. Pass0 is the pass through interface. You'll need it in order to use camcontrol or xmcd. > 2.

I'm looking at alternative ways to get the information that may be more robust. It seems that the adapter doesn't like having lots of outstanding SCSI commands when you make this request. > 3.

Probably because the controller hadn't finished negotiating with the drive when we asked. We have no way of easily ensuring that the negotiation has taken place unless we force the card to probe all devices. Forcing the card to probe them all may fail if a device can't handle multiple luns (which the SCSI code probe will avoid), so I wanted to avoid that. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
