Hi All,
I set a hardware RAID system with ARCO's Duplidisk for
my FreeBSD server, and sometimes finds messages as follows;
ata0-master: no status, reselecting device
[my hardware environment]
Mainboard: Asus P/I-P55T2P4 Rev.3.0
CPU: Pentium166
RAID Card: DupliDisk ROM Rev.2.09P (NOT DupliDisk II)
http://www.arcoide.com
HDD: Maxtor 90845D4 (8.4GB) x 2
OS: FreeBSD 4.3-RELEASE
[dmesg output]

ata0-master: no status, reselecting device
-----------------------------------------------------------------
* According to some DupliDisk's FAQ,
http://www.cybernetech.co.jp/product/duplidiskfaq.html (sorry,
in Japanese) it is written that it uses PIO4 for data transfer
by default.
But, as shown above, it is PIO3 under my environment.
[for reference]
When connected HDD directly with Mainboard (without DupliDisk)
dmesg says;
ad0: 8063MB <Maxtor 90845D4> [16383/16/63] at ata0-master WDMA2
^^^^^^^
Well, I thought it is because my kernel is reselecting
HDD's transfer mode at intervals.
So I added the following line to /boot/loader.conf.
hw.ata.ata_dma="0"
and forced to select PIO mode, when booting.
Nevertheless, "ata0-master: no status, reselecting device"
appears on my console!
FreeBSD seems to run correctly, but I am quite anxious
about this message.
Oh! Could you advise me if it is because of some system
disorder and it is necessary to do something to fix it,
or it doesn't matter, and it's all right to leave it.
Thanks.
Best Regards
