Hi,
We're using gmirror on our sun fire x2100 and FreeBSD 6.1-p10. Some
days ago I found this in the logs:
Apr 1 02:12:05 x2100 kernel: ad6: WARNING - WRITE_DMA48 UDMA ICRC
error (retrying request) LBA=612960533
Apr 1 02:12:05 x2100 kernel: ad6: FAILURE - WRITE_DMA48

disconnected.
Normally it looks like a disk error, but I think our half year old
disks (WD RE2) shouldn't fail after this short time. Of course they have
moving parts so they MAY fail. :( Yesterday I tried to reinit the sata
channel and insert the disk back into the mirror. I got this:
Apr 3 23:00:32 x2100 kernel: GEOM_MIRROR: Device gm0: provider ad6
detected. Apr 3 23:00:32 x2100 kernel: GEOM_MIRROR: Device gm0:

(retrying request) LBA=392960
Apr 3 23:00:53 x2100 kernel: ad6: FAILURE - device detached
After this, the disk disappeared from the sata channel completely.
The wierd is that we used the onboard nvidia-raid and the very same
error occured, but there was no report in the kernel the machine just
don't asked for operating system. Later I found out that the disk was
forgotten ~2 weeks before that reboot (data was ~2 week old on it).
Otherwise that
"forgotten/failed" disk was also half year old and was fine without a
problem.
Is there anybody who experienced something similar with SUN X2100 or
any other servers running FreeBSD 6 and sata?

Hi,
I can confirm your problem. I have same problem on one X2100 but not on
the others. Currenty I have 4 X2100 machines, but only one with this
strange problem. The problem is not caused by HDD it self, I tried to
replace it with brand new and same error appears after few days. May be
there are some problems with cables / connectors or something on
mainboard. I am well known by problems with SATA(n) disk drives problems /
disappearing on this list and local (czech) mailing list. I had similar
problems on ASUS boards with Intel chipsets... so in my point of view -
there is something bad with SATA in general. I never had problem like this
with old good ATA drives.
I have not solution for this problem. Disk is OK after reboot for a few
dasy or weeks... if there is somebody which can help with investigating
this kind of problem, I'll be happy to cooperate.
output of dmesg, smartctl, gmirror etc.:

Hi,
May I ask that when did you buy that machine with the problem and the
Machine with problems was bought at December 2006 (made at October
2006), first machine was bought at summer 2006, next to machines leased
earlier at 2007 (I don't know when bought / made)
