Solaris 10 U11 Live Upgrade - Errors when patching an ABE on Solaris 10, then unable to ludelete

I hit the following error when trying to apply Solaris 10 U11 patches to a newly created ABE:

[root@reg2uxap0962:liveupgrade/10_Recommended] # time ./installpatchset -B sol10u11 --s10patchset
ERROR: Failed to mount boot environment 'sol10u11'.

real    0m27.535s
user    0m6.447s
sys     0m7.401s
[root@reg2uxap0962:liveupgrade/10_Recommended] #

I tried to delete that ABE using ludelete, but I get this error:

[root@reg2uxap0962:liveupgrade/10_Recommended] # ludelete sol10u11
ERROR: unable to mount zones. Error message follows.

I know that /opt/VRTSpbx is the problem, it shows as a lofs FS on the zone config. I want to redo the ABE excluding that path, but I cannot delete the current ABE.
