Re: Lun resizing?
This is not true. Although most/all storage vendors allow you to grow a LUN (within reason)...Most/All host OS's have limitations on how big a LUN can be. Plus you need to throw in the fact that without some host-side software the OS will not know that you have grown/shrank the LUN (shrinking a LUN adds another conversation completely). Because a LUN (in most cases) are contiguous blocks on disk and are "pre-allocated" (depending on thin-provisioning), shrinking a LUN in some cases is not only difficult but could be impossible (EMC). You would need to create a new "smaller" LUN and copy all data to it and destroy the original. This is because most systems do not have a way to differentiate 1's and 0's inside the LUN from "usable data" and/or "sparce data".
