It's not easy, no.  Depending on what you're trying to accomplish, 
exactly, it may be possible doing a cluster failover and giveback, though. 
It's not really supported, especially for customers, but professional 
services still has a few tricks up their sleeves.

I don't mean to take away anything from Isilon -- they have a really cool 
system with a lot of advanced functionality, and you can get a tremendous 
amount of performance out of them.  I wish they had better snapshots 
functionality, but that's not really their priority market anyway.  The 
way you can set up different file-level replication (RAID-ish) protections 
at the directory level is nifty, too.
