JKnc> You have to setup the RAID-1 volume in the LSI BIOS.
JKnc> The normal motherboard BIOS is supposed to execute the bootrom in the
JKnc> LSI card, which will allow you to enter the LSI BIOS.
JKnc> If I remember correctly it's "control-C" on bootup, instead of "DEL".
JKnc> Then you select new IM volume (Integrated mirroring)
JKnc> You can migrate your main disk to the volume, and your second disk will

I described in my first message, that RAID was setup in BIOS, but
FreeBSD can't see it's raid. It is main problem! ...not "event 0x16"
problem
Once again:
---
In system BIOS I set
Mass storage controllers menu
SAS controller - Enable
SAS configure as SW RAID - Enable
RAID was build in controller's BIOS (CTRL+E during boot).
---
We talking about Intel 5000PAL + SAS backplane
There is LSISAS1054E chip and 3 SAS Ports 1U Active Backplane and Intel Embedded Server Raid
Technology II for RAID setup (CTRL+E during boot)
FreeBSD can't see raid

JKnc> How I can test it...
JKnc> First of all FreeBSD should see RAID, but it only see separated HDD

JKnc> This is the problem that I described
