That's also FRAID for the sil controller. If you can don't use the
sil's FRAId use MD which is built right into the kernel.

I've two machines with almost identical hardware (slightly different

One of the servers was installed a while ago by someone else, it's
running Fedora Core 5 and RAID is enabled:
# df -m
Filesystem 1M-blocks Used Available Use% Mounted on
/dev/dm-6 125931 2990 116441 3% /
/dev/dm-1 99 13 81 14% /boot
tmpfs 1012 0 1012 0% /dev/shm
/dev/dm-2 9917 151 9254 2% /tmp
/dev/dm-3 9917 237 9168 3% /var
# cat /etc/modprobe.conf | tail -n 1
alias scsi_hostadapter sata_sil
I installed CentOS 4.4 64bit on the other system, but I could not enable
RAID. The installer was always seeing 2 separate drives instead of one
RAID device.
Was it my mistake? Did I not enable the proper settings in the BIOS? (I
tried quite a few different settings)
Or is it perhaps that the CentOS kernel does not have the proper drivers
to support SiI 3114 in RAID mode?
It is most likely that the current kernel does not support the RAID in
that scenario, though I am not sure.
Looking at the latest testing kernel's changelog that we have built in
the testing repository (2.6.9-42.37), I do not see any added support for
Sil 3114 RAID to that kernel (that would not be in the standard
kernel) ... though there are sata_sil and sata_sil24 kernel modules in
the standard kernel that depend on libata. No idea if they support RAID
though.
The 2.6.18 kernel in CentOS5 will have more hardware support and most
probably support for those options, if they are in FC5.
You might try rhel5b2 (downloadable from the upstream provider) on that
machine if you don't need it in production immediately ... as CentOS 5
should be a fairly easy upgrade from there _OR_ use software RAID with
the C4 kernels.
Also I found this page to see about getting drivers:
http://www.siliconimage.com/support/supportsearchresults.aspx?pid=28&cid=3&ctid=2&osid=2&;
On the FC5 machine you can do:
lsmod
And see all the modules loaded ... also look in /etc/sysconfig/hwconfig
as it may list the module for the controller.
You can then look for that module name with the modinfo command on
centos-4.
