>Description:
Hi,
I have purchased motherboard intel se7230nh1-lx, and wished to create on her basis RAID10. Made as it is written to documentation.
Has entered in bios, has chosen 4 disks, has told that they in raid10, initialized, rebooted.
At loading the system speaks that status RAID OK, but at loading the FreeBSD informs that RAID DEGRADED.
RAID it is made in ICH7R on LSI v3 embedded MegaRAID.

Help me PLZ.
P.S.
Also I have found out, that if to try to create RAID through atacontrol controller is found out as Intel MatrixRAID.
It occurs because of that that function ara_raid_create in the driver ata at creation RAID does not check a format of existing structure metadata by means of function ata_raid_read_metadata, and simply causes pci_get_vendor.
I have not understood, it specially so is made, what it would be possible to try to create RAID with structure not native for the controller or simply have not added a code still?
>How-To-Repeat:
To create RAID by means of ICH7R embedded LSI v3 MegaRAID using all four channels.
>Fix:
I have found similar PR, but this patch is not established on 6.1-STABLE, and 7.0-CURRENT,
and I do not have not enough qualification what to correct him.
