It's been a long time since I have made these sorts of changes, so I
think it best I double check my memory.

We are making many changes to our disc drive configuration this weekend,
and I want to do this with the least
amount of pain (ok, work).

We will be removing some of the old 4gb full height discs from a HASS
unit and replacing them with the 4.3gb low profile discs.
In addition we are adding mirrored discs for a couple of private volume
sets (non_system_volume_sets ;-)

1)  The 4.3gb low-profile discs I am adding have different model numbers
in ODE
ST34371W,  ST34572WC, and  ST34573WC   even though they all look the
same.  
Does it matter what I configure them in as?

2) because I will be moving discs around, and adding discs to the volume
sets, I think the best bet is to delete
all of the LDEVs and completely read them from scratch.  This means I
also should scratch the volumes add them 
back to the appropriate volume set and then restore the data.

Am I missing anything?
