I am going to contact DPT tomorrow about obtaining the NDA-bound specs for the board. We have some development talent in-house to commit to stabilizing this driver. Our choices are either: a) wait for Simon to stabilize the driver b) try to stabilize the driver ourselves, release code back to FreeBSD c) scrap FreeBSD on this HA server (Solaris,Linux,NT all have native support for DPT) d) scrap DPT and use a SCSI-to-SCSI based RAID solution Given our current committment to DPT and FreeBSD so far, I'd prefer a or b above. I'm not confident of a) happening quickly, as Simon appears to be either busy with other projects or relatively unavailable. As for b) we're mostly application hackers, not driver hackers, so it may be a stretch. -Troy Cobb Circle Net, Inc. http://www.circle.net > -----Original Message----- > From: Julian Elischer [mailto:julian@whistle.com] > Sent: Friday, May 29, 1998 2:33 AM > To: tcobb > Cc: 'Greg Lehey'; 'Mike Smith'; 'freebsd-current@freebsd.org' > Subject: RE: DPT driver fails and panics with Degraded Array > > > I guess this is really something you want to discuss with simon. > I'm sure he will contact you soon > He's just finished moving houes and has been out-of-touch fro > a few weeks > > julian > > > On Fri, 29 May 1998, tcobb wrote: > > > > -----Original Message----- > > > From: Greg Lehey [mailto:grog@lemis.com] > > > > > If you just want to report a bug, use send-pr.
