Hello guys, I have this problem and i need yours councils.
I have two machine linux with installed Fedora core 4.
This machines have one host controller SCSI 160 Qlogic QLA10162 with 2 exit LVD.
This controllers of this two machines have connect on disks array (cluster solution).
On disk array I have 6 disks SCSI therefore configure :

Stripe md10
_________________
Disk 1 Disk 2 Disk 3|
________________|

Stripe md20
________________
Disk4 Disk 5 Disk 6|
________________|

md10 ____
md20 ____|____ Mirror md100


I have configure this disks with mdadm :

ARRAY /dev/md10 level=raid0 num-devices=3 devices=/dev/sdf1,/dev/sde1,/dev/sdd1

ARRAY /dev/md20 level=raid0 num-devices=3
devices=/dev/sdj1,/dev/sdi1,/dev/sdh1

ARRAY /dev/md100 level=raid1 num-devices=2
devices=/dev/md10,/dev/md20

On boot i launch
/sbin/mdadm --assemble --uuid=975f7468:1e6eceb5:480f2a0d:b8a518e1 /dev/md100 1>/dev/null 2>/dev/null


When I connect 2 controllers on array i get kernel error SCSI when i boot on second machine,
but when I connect only machine one time on array function correctly.

How I can shape my Array with mdadm Multipath storage?
I have configure my array with another software clustering?


Thanks in advance.

I use a product from ADIC called Stornext and a Qlogic switch to control all the LUNs to our Datadirect storage. It works pretty good, but it's pretty expensive. I wish I had more to help for you...

but this product succeeds to avoid the errors scsi to the boot kernel? why I have the prefeeling that mine is an error of driver
