Hi all!
I have a problem installing FreeBSD 9.0 on Fujitsu Primergy RX200 S5
server with LSI MegaRAID SATA controller (two SATA HDDs in RAID1
array). When booted from a CD, FreeBSD doesn't recognize RAID Array,
it recognizes HDDs only (ad4 & ad6). On the same server, FreeBSD 8.3
installation recognizes RAID Array (ar0).
pciconf -vl on FreeBSD 9.0:
ahci0@pci0:0:31:2: class=0x010400 card=0x11501734 chip=0x3a258086
rev=0x00 hdr=0x00
vendor = 'Intel Corporation'
device = '82801JIR (ICH10R) SATA RAID Controller'
class = mass storage
subclass = RAID
So it's not an LSI MegaRAID, but an Intel Controller?
I found this on the net:
quote from:
http://serverfault.com/questions/275875/raid-bus-controller-intel-corporation-82801jir-ich10r-sata-raid-controller
"ICH10R-based RAID controllers are so called fake- or software-RAID
controllers, the OS needs to do all the work."
What you have on 8.3 might be a software raid,
one way to get it:
gmirror label ar0 ad4
gmirror load
gmirror insert ar0 ad6
You now have ``/dev/mirror/ar0'' as device node for your software RAID,
check:
gmirror status
pciconf -vl on FreeBSD 8.3:
atapci0@pci0:0:31:2: class=0x010400 card=0x11501734 chip=0x3a258086
rev=0x00 hdr=0x00
vendor = 'Intel Corporation'
device = 'SATA RAID Controller'
class = mass storage
subclass = RAID
dmesg output on FreeBSD 8.3:
# dmesg|grep ar0
ar0: writing of DDF metadata is NOT supported yet
ar0: 952720MB <DDF RAID1> status: READY
ar0: disk0 READY (master) using ad4 at ata2-master
ar0: disk1 READY (mirror) using ad6 at ata3-master
As far as I understand (while I don't have that much FreeBSD
experience), amr is the appropriate driver for this controller. Tried
to load it manually (kldload /boot/kernel/amr.ko) but it seems the
driver is already present in kernel.
What am I missing here?
Thanks!
