No, you can add an extent to a datastore non-disruptively.

I went to Extend Device and i get a ! Warning: The current disk layout will be destroyed. All file systems and data will be lost permanently.

Are we sure?

That message is scary, but what it is refering to is any data on the extent.  Not the current LUN.  Check out this thread on the VMware Communities forum:

After a rescan on all hosts to see the increased size of LUN the extent worked without data loss. You are correct sir. Thank you again!
