Good day,
I trying to test sw target and initiator.
My config: two servers with intel x540 connected back-to-back(vn2vn).
Centos 6.4, software from official centos repo, not latest!:
fcoe-target-utils.noarch 2.0rc1.fb16-3.el6 @base
fcoe-utils.x86_64 1.0.24-2.el6 @base
node0 target
node1 initiator
What I've done:
1) echo eth1 > /sys/module/libfcoe/parameters/create_vn2vn
on both nodes
2) on target

Now I trying to fdisk /dev/sdc
But got:
"Unable to read /dev/sdc"
What I missing? Maybe I need to try latest versions of fcoe-target-utils and
fcoe-utils? latest kernel, another distro?
Thanks,
Alexey.
