I am in the process of trying to setup a Dual Xeon machine with a Silicon
Image 3112 SATA controller. The system is booting from a parallel ATA disk and
there are two SATA disks being used to store data.
I was able to access the SATA drives, both in a raid0 and non-raid
configuration, using the driver (sii3112rl.o) with the machine. This module
was compiled for a uni-processor RH8.0 kernel (2.8.18-14). We were getting
transfer rates of around 40MB/s in non-raid and 80MB/s in raid0. There was no
SMP version of the module supplied so it was kind of useless to us.
So, I tried a 2.4.21-pre6 kernel (SMP with hyperthreading). The 3112
controller was identified at boot and I was able to access the disks. However,
hdparm was reporting very poor transfer rates, around 1.8MB/s. It turned out
that DMA was not enabled on the disks. When I enabled DMA I got back to a
transfer rate around 40MB/s. I set the transfer mode to udma6.
Then I tried to make an ext3 filesystem. mkfs would get up to around the 240th
inode table (ie: "Writing inode tables: 240/xyz") and then freeze up for a
while. The following errors were displayed on the console:
hde: dma_timer_expiry: dma_status == 0x21
hde: timeout waiting for DMA
hde: timeout waiting for DMA
hde: status timeout: status = 0xd8 {Busy}
hde: drive not ready for command
ide2: reset phy status=0x00000113 siimage_reset
ide2: reset timed-out, status=0xd8
hde: status timeout: status = 0xd8 {Busy}
hde: drive not ready for command
ide2: reset phy status=0x00000113 siimage_reset
ide2: reset timed-out, status=0xd8
followed by loads of IO errors. After this, the disk was uncontactable. I
thought the problem might be with udma6 so I tried all of them but with the
same problems. I also tried 2.5.66 and a RedHat 2.4.20-2.54 kernel but these
had the same problems. If I turned DMA off I was able to make a filesystem
(although very slowly). I was also able to make a filesystem using the
original supplied driver.
The timeouts also occurred if I used the silraid module and accessed the disks
via /dev/ataraid/d0.
I could swap the drives for parallel ATA ones but would rather get the SATA
ones working if possible. I recall reading a message from Andre containing
performance details about a 3112 controller and Linux raid 1, so I presume
that it is possible to get this configuration going and it is just that I am a
doofus.
Here is some info on the machine:
