Hi
So I have ldoms 1.2 and SC 3.2 latest release + patches etc.
strangely enough I don't seem to be able to disable the fencing.

This is an internal disk exported to two guests via ldm add-vdsdev -f
option.
in primary I have

/dev/dsk/c2t5000CCA00053682Cd0s2
shared
/dev/dsk/c2t5000CCA00053682Cd0s2
I cannot use cldevice on any disk in any of my guests, except for the
root disk, which is a zfs based disk image, the other entire disks ( ie
added slice 2 of the disk to the vdisk server, then on a vdisks to my
guests ) cannot be seen via cldevice, perhaps I am doing something wrong
though.
