3494 Dual-Gripper Work

[T.Y. Wu]

We are about to install the dual-gripper feature in the 3494.  This
means we will lose a few cells at the top and at the bottom.  After
re-inventory, we should get all the volumes correctly identified in the
library.   My question is: anything I need to do on the TSM side for
this change?   T.Y.
