ESXI 4.1 LUN maping question

I normally don't work with ESXi 4.1 and want to confirm something:

I have presented a test LUN to the host not made a datastore out of it or anything.
SO it sees the LUN when you click the devices tab I can see the naa. and it says mounted

Can I just delete volume from the SAN without causing a APD or PDL? As there is no I/O going to it or anything?

Might be a stupid question, but I would rather ask it then not!

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Yes, you can. Delete from SAN, and issue a Re-scan HBA or iSCSI software adapter.
