--Apple-Mail-8--534908674 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii actually we were having a similar experience with the smartarray p212... = attached a SAS tape changer (tandbergdata lto-4 autoloader) to it, but = could only see the tape drive, not the changer. in our case, the p212 = was the second smartarray controller on the bus (ciss1), with a P410 as = the primary one. i believe there's a bug about that as well. to = contrast, another machine with an IBM serveraid SAS controller and the = same tape changer works quite nicely out of the box with FreeBSD 8.0. please get in touch with me if you're a developer and want to see a = dmesg or similar.. :) cheers, /folkert On 6 Jul 2010, at 15:04, frank cheong wrote: > Riding on > http://www.experts-exchange.com/OS/Unix/BSD/FreeBSD/Q_26283427.html as = well > as > = http://www.pubbs.net/200911/freebsd/20344-ciss4-not-seeing-multiple-luns.h= tml > I would like to know if there is any way to manually create/link the > /dev/ch0 driver for this case. >=20 > Actually, I have my msl 2024 1760 SAS tape library attaching to my HP = DL 180 > G6 thru Smart Array P212.
