Can I do lun resize of live vmware lun? What are the steps in Vmware (just rescan?) any consideration?

Well, one important thing to know is that (afaik) VMFS3 doesn't support resizing so:

1. You cannot shrink the LUN without taking the chance of possibly corrupting the data on it 2. You cannot grow the LUN and expect VMFS3 to take advantage of the new space.

What you can do is concatenate a new LUN to an already existing datastore, which VMWare calls extents, but that would mean that if one of the two LUNs would get corrupted, you're SOL.
