[Xen-users] Xen Dom0 with FibreChannel (FC) can't export disk to DomU

[Dietmar Simons <info@xxxxxxxxxxxxxxxxxxxx>]

Hello all,

I have a problem with Xen and FibreChannel.

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:
