so, I found the answer. apparently reading the isilon 7.1 cli guide was my mistake, I needed to read the 7.1.1 cli guide as they updated the isi worm command in 7.1.1.  'isi worm domains create --mkdir' is the NEW command in 7.1.1. Not sure if this changes in the 7.2 release as I have not read the 7.2 cli guide.  a little frustrated here and I apologize for any sarcasm.
so, i'm testing out the smartlock features on my 7.1.1.2 cluster. I licensed smartlock and read the processes on how to create a smartlock folder. the cli states to use: isi worm mkdir --path  but the mkdir comes up as an invalid option (or bad subcommand).  performing a isi worm --help doesn't give me the mkdir subcommand option and I only get 3 options: cdate domains files  'isi worm domains' has the option 'create' to create a smartlock domain but does not have the mkdir option.  I don't understand what I am missing here? Do I need to 'enable' anything else? I am assuming I am in 'enterprise' mode on my particular cluster.  the cluster was a 6.5 upgrade to 7.x and everything I read states that smartlock is available as 'enterprise' mode.  Thanks.
