vSphere 4 LUN removal issue

Please see this original post for information on a vSphere 4 storage bug that appears to be getting several people.

It deals with removing a LUN from the server…and the order you perform the process. The proper sequence is:

1. In the vSphere client, vacate the VMs from the datastore being removed (migrate or Storage vMotion)
2. In the vSphere client, remove the Datastore
3. In the vSphere client, remove the storage device
4. Only then, in your array management tool remove the LUN from the host.
5. In the vSphere client, rescan the bus.
