[SunHELP] live upgrade, empty dataset error

[Shannon]

I have a PC server running Solaris 10 and want to apply patches.

I tried to create a new BE but its failing with an empty dataset name, and I
cannot figure out why. I have checked the zfs properties for the current root
and none are empty and all look correct.

I removed and recreated /etc/lutab as well.

Error follows, ideas appreciated:
