Re: How to properly unpresent/remove LUN from Vmware.
For the most part you are correct. Below is a are the steps I would recommend following.
1. Verify no I/O is going to the volume.
2. Remove datastore from hosts.
3. Unmount volume from hosts.
4. rescan storage adapter inside ESX.
5. Remove IQN access inside array.
6. Set volume offline.
7. Delete volume.
Let me know how it goes.
