Folks,

We have a very large db replicated to a VMAX, running 5876 code, from the R2 we have 4 different test,dev,Backup,QA clone copies.  We figured we could save a ton of space using nocopy clones, none of these environments require high performance.

The problem is the default behavior on a nocopy clone is copy on access.  How do we change that behavior to copyonwrite?

We have thought about changing the whole operation and using the new -vse and making it a Snap but like the idea of being able to make it a full clone copy if the need arises.  Thanks in advance.

If anyone has good documentation on the differences between a nocopy clone and the vse option that would be welcome as well.
