Changing a RAID configuration - Adding/removing disks

[Pete Helgren <Pete@xxxxxxxxxx>]

I have a customer with a new i5 520 that we added 4 drives to.  It 
originally had 4 drives and we added 4 more.  The problem is that I 
added the new units to the existing ASP (1) and it turns out the new 
drives were a different size and model than the original 4 so they 
couldn't be added to the RAID parity set. I need to correct this before 
we go into production.

So, what I'd like to do is get these new drives as part of a protected 
raid set.  Current disk protection status is:

            Serial                  Resource                
ASP  Unit   Number      Type Model  Name        Protection  
  1                                             Unprotected 
        1   68-0D9C14B  4326  074   DD002       Device Parity
        2   68-0DD6772  4326  074   DD004       Device Parity
        3   68-0DD7645  4326  074   DD003       Device Parity
        4   68-0DD75EF  4326  074   DD005       Device Parity
        5   68-0DCE4C6  4327  050   DD008       Unprotected 
        6   68-0DCB227  4327  050   DD001       Unprotected 
        7   68-0DCF3A4  4327  050   DD006       Unprotected 
        8   68-0DCD5D9  4327  050   DD007       Unprotected 

I think I can make the 4327 drives part of a different ASP and then they 
can be part of a RAID set (correct?)  The storage controller displays as 
a 573D when I use Work with Storage Resources.  Or, is there a better 
way to do this?  Also, I have typically worked with smaller system that 
have only one ASP, is there a downside to multiple ASP's?

If I do remove the 4327's from ASP 1 and create a new ASP, how do I move 
data off of them?

Just need a few pointers on how to proceed.
