Preferred way will be to use NST. However, if you are quite confident and the HS drive is not in use, you may do it manually as well.  Sandip
Just checking to make sure I do this right...  Do I need to use NST to remove the old one before puting the new on in?  I'm assuming I need to destroy the HS RG first.  Once it is an "unused" disk, can I just pop the old one out and put the new on in?   Dan
