Thanks for the post! I have clients that are using our CLI to automate snapshots and clones all of the time. Email me @ Panda@nimblestorage.com and I will send you our cli reference guide and reference vol --clone.
also I will ping my piers for some scripts that might help you as a frame work.
That's a good thread here on creating scripts to automate the taking of clones and mounting them to a speciifc host:
There's also a sample script towards the bottom of the thread that does exactly that was created by Adam Herbert
Inside that script you should be able to set Initiator Group that the clones get mounted too
