can't recognize hp msl 2024 attaching p212 on FreeBSD 8 p3

F

I have a brand new HP MSL 2024 LTO 4 SAS auto tape library attaching to Smart Array P212 on my DL180 G6 server running on FreeBSD8 p3.

I have no problem in using the tape drive thru " mt -f /dev/sa0 rewind" or even " tar -cvf /dev/sa0 testing.txt" while whenever I tried to access the loader thru " mtx -f /dev/ciss0 inquiry" or " mtx -f /dev/sa0 inquiry" without luck and I have also tried to use the chio with luck either.

I did upgrade the firmware version of the Smart Array P212 to the latest available. What kind of information should I provide?

server# chio -f /dev/sa0 move slot 9 drive 0

What is going on and what else should I try?

Does that means freeBSD cannot recognize the tape library and haven't build the ch0 loader driver?
 
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.html
I would like to know if there is any way to manually create/link the /dev/ch0 driver for this case.

Actually, I have my msl 2024 1760 SAS tape library attaching to my HP DL 180 G6 thru Smart Array P212. I can successfully use this tape library with my window 2008 ad backup exec 2010. While from my freeBSD 8.0, 8.0 p3 or even 8.1 RC2, I don't even see the /dev/ch0 device link whereby I can see this device using the camcontrol. My question is: -

1. Is there any way I can manually create/link the /dev/ch0 device driver ?
2. How can I achieve 1 if it is possible.
3. Having learnt that exposing disk mirror controller should be considered as danger, may I have more information and background information about that ? What specific problem will I encounter for that ?

Pls find below the configuration details which is related to the tape library:-

After installing redhat linux with drivers downloaded from hp website on the same setup, I found that the problem should be the ciss driver in freeBSD which didn't handle lun > 0. Coz rehat works nicely with the changer only when using the drivers provided by HP (that means redhat also can't recognize this tape library using the default ciss driver/setup). Sad news is I will have to stick with redhat linux when everything works in order to save some money from grabbing another controller which suppose to work with freeBSD. I keep this post here hopes other will not fall into the same HP P212 related media changer problem or best if someone will enhance the ciss driver in order to handle device with lun > 0.
 
Haven't you tried to manually scan lun 1 of that device with camcontrol rescan 1:6:1
?
Also, for information, CAM in 9-HEAD recently got new lun scanner routine.
