Happy weekend John! I posted in the CR that while they are doing the work to 
increase it to 256, they might as well bump it all the way up to 65536 or 
sizeof (int). 

What build is that "alias" fix in? I made a little modification to my 
"iscsi-disk" script to allow luns just like that. I think I might have even 
sent it out? I was going to blog it, but I haven't gotten there yet.

Here is what I have so far...

(note: this is part 1 configuring iSCSI, part 2 will be creating the "first" 
xvm, part 3 will involve clones)
