We have some LaCie 1 TB external disks which work fine on
other Linux servers (running Red Hat 9, and Ubuntu 7.04),
but which fail to be seen on our CentOS 4.3 system with
kernel 2.6.9-34.107.plus.c4smp
The interface card is a Sunix 64 bit Firewire 800 ieee1394b
adapter plugged into a PCI slot in our Linux server, which
is a Tyan Thunder K8SD Pro S2882-D, 64 bit AMD Opteron CPU
Using "cat" to examine the "/proc/scsi/scsi" information shows
our system hard disk and internal RAID array:
cat /proc/scsi/scsi
-------------------
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: WDC WD360GD-00FL Rev: 33.0
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi4 Channel: 00 Id: 00 Lun: 00
Vendor: AMCC Model: 9550SX-8LP DISK Rev: 3.01
Type: Direct-Access ANSI SCSI revision: 03
I have found various items in the centos list archives,
but none of these has provided a definitive solution;
I have used commands such as "lspci", and "lsmod" to
ensure that the system sees the firewire card, and has
iee1394 and other modules loaded:
lspci | grep 1394
-----------------
01:03.0 Firewire (IEEE 1394): Texas Instruments TSB82AA2 \
IEEE-1394b Link Layer Controller (rev 01)
lsmod | egrep '1394|sbp2|s.*_mod'
---------------------------------
sbp2 26825 0
ohci1394 36953 0
ieee1394 124601 2 sbp2,ohci1394
sd_mod 19393 7
scsi_mod 140561 4 sbp2,3w_9xxx,libata,sd_mod
Somewhere I found a note about trying the "serialize_io=1"
option with the "sbp2" module, and now have tried that,
but still have no joy:
dmesg | grep sbp
----------------
sbp2: $Rev: 1219 $ Ben Collins <bcollins at debian.org>
sbp2: $Rev: 1219 $ Ben Collins <bcollins at debian.org>
ieee1394: sbp2: Driver forced to serialize I/O (serialize_io = 1)
The "1394" messages in "dmesg" are:
dmesg | grep 1394
-----------------

If anyone can suggest how I might proceed to get our LaCie disks
to run on the Firewire card under CentOS 4.3,
I shall be delighted to see what I need to do, thanks
