Re: [Xen-users] Xen Dom0 with FibreChannel (FC) can't export disk to Dom
Hello,
thanks Ulrich for your answer.
You have right, it is not the type of cable, but it is the driver!
At first, I use the kernel LSI mpt drivers.
It doesn't work, I can't export an image or a partition from Dom0 to a
DomU.
Now I get the original LSI drivers from the LSI Homepage and build new
fusion/mpt modules for my kernel.
What should I say: It works!!!!!!
I can now export an image or a partition from Dom0 to a DomU as hdx or
sdx.
Thanks all for your help
Wish all the best

Hello all,
I have a problem with Xen and FibreChannel.
You should says "XEN and Samba". The type of cable should be irrelevant here.
The Dom0 can't export a Disk on a FibreChannel SAN-Box to the DomU's.
In the DomU configuration I try:
disk = [ 'phy:/dev/sdb1,/dev/sda1,w' ]
or
disk = [ 'file:/mnt/sambashare.img,sda1,w' ]
sambashare.img is a 512MB great Diskimage on a Partition on the FC-SAN-Box,
the Dom0 mount this partition on /mnt and the Filesystem is ext3.
The Xen Dom0 can mount every Partition on the FC SAN-Box.
Some information about my Server:
Dell PowerEdge 1950
FC-HBA is a 7104 from LSI
2GB RAM
DualCore Xeon
Kernel: 2.6.16.29-xen
And here the output from lsmod in DomU:
