Hi,
Probably I the idiot since recently has purchased a motherboard from
intel SE7230NH1-LX.
And now I try to get on her RAID, all over again I tried to make RAID10.
But in reality, she has problems and with RAID0 and RAID1 if them to use
at once two
As it has appeared on ICH7R RAID it is made through LSI embedded
MegaRAID V3.
After I have created RAID10 in BIOS system to me have given out the
following:
/...
atapci0: <GENERIC ATA controller> port
0x2040-0x2047,0x2050-0x2053,0x2038-0x203f,0x204c-0x204f,0x2020-0x202f

/ar0: WARNING - mirror protection lost. RAID1 array in DEGRADED mode/

/...../
That is connected into RAID only first and last HDDs.
If to create simultaneously RAID1 and RAID0, in RAID they connected too,
only they, both.
After some experiments, I have understood - work rotten.
After has tried to create RAID by means of atacontrol, he has given out
me the following:
/# atacontrol create RAID0+1 128 ad8 ad10 ad12 ad14/
/ar0: 305255MB <Intel MatrixRAID RAID0+1 (stripe 64 KB)> status: READY/
/ar0: 625163520 sectors [38914C/255H/63S] <> subdisks defined as:/
/ar0: disk0 READY (master) using ad8 at ata4-master/
/ar0: disk1 READY (master) using ad10 at ata5-master/
/ar0: disk2 READY (mirror) using ad12 at ata6-master/
/ar0: disk3 READY (mirror) using ad14 at ata7-master/
It was created... Has tried to work, like works, but at reboot BIOS has
given out the message on that that RAID not configured.
But the system was normally loaded and has shown me:
/ar0: 305255MB <Intel MatrixRAID RAID0+1 (stripe 64 KB)> status: READY/
/ar0: 625163520 sectors [38914C/255H/63S] <> subdisks defined as:/
/ar0: disk0 READY (master) using ad8 at ata4-master/
/ar0: disk1 READY (master) using ad10 at ata5-master/
/ar0: disk2 READY (mirror) using ad12 at ata6-master/
/ar0: disk3 READY (mirror) using ad14 at ata7-master
/
I began to test system, and finally she rebooted with Fatal Trap.
Business has appeared even worse.
I have removed RAID created through atacontrol and have created it anew
in LSI embedded RAID.
I has started to investigate source codes.
Has established a variable testing in 1 into
/usr/src/sys/dev/ata/ara-raid.c - has received following dmesg:

In general, I looked through source codes much, but have found only the
reason on which atacontrol specifies that it MatrixRAID:
Function ata_raid_create determines type of the chip only on pcivendor
(i.e. in my case 8086) and does not consider a format already
established metadata as it does ara_raid_read_metadata.
Can be it is meaningful lead to their identical kind or allocate in
separate function for example ara_raid_ident?
On greater my knowledge has not sufficed and further only questions :)
1. Where it is stored metadata on HDD or memories of the controller?
2. Whether probably to determine the maximal size metadata or it is
identical to all controllers?
3. Why to not use for Intel/LSI the driver amr?
4. In what place BSD determines which driver to substitute?
5. Where to find a format metadata?
I have some more questions, but these will help assist me for
construction of a course of an idea more.
Can be bad I googled - I apologize - specify a finger :)
Best regards GreenX.
