As far as I'm aware of and having worked on it for a similar requirement; NetApp don't have a documented procedure for it, but insist on performing recovery in consulation with P1 support. This is only possible if it is a production system, and not with a evaluation or demo version.
I've simulated node crash and VM crash scenarios and recovered; however, they were done in collaboration with NetApp team members. There are multiple steps and have to be done cautiously.
If there is potential for you to purchase a full version of the software post evaluation, then I would suggest working with Netapp account support/sales teams and you performing the crash/recovery test before go-live with a full licensed version, thereby you gain all acceptance tests.
