SATA RAID Problems

Sun Jan 6 14:57:13 PST 2008

Hi

I just bought a new Server (a Fujitsu Siemens PRIMERGY Econel 100)
with 2 x 160GB disks (ad4 and ad6) and added a 1TB disk (ad8).
Configuring the two 160GB disks ar a RAID1 in the LSI MegaRAID utility
works without problems, but when I boot FreeBSD (FreeSBIE 2.0.1 or a
bootable 7.0 RC1), the RAID consist of ad4 and ad8 (see dmesg below).
I tried to delete the RAID configuration from the disks (I never
configured the 1TB disk into the RAID in the first place) via LSI
utility, atacontrol delte and dd'ing the head of the disk from
/dev/zero but nothing worked. When I unplug ad8, the RAID is displayed
as consisting of ad4 and ad6 as expected.
When I change the SATA Controller from RAID to Native, atacontrol
displays the correct drives (ad4 and ad6) to belong to ar0.

Furthermore, the througput rate of the disks is very meager, ad4 and
ad6 make around 5MB/s, ad8 only 0.5MB/s.

any ideas?

thanks

Stefan
