Hi Tom, 

What model controller do you have? I expanded a our raid 5 array on a Compaq 
Proliant 1500 using a Smart 2DH raid controller with NT 3.51 back in 1998 when 
I supported the servers at LSI Logic and it worked with out having to recreate 
the array. Glenn is right that lower end Proliant controllers did not support 
this option. 

As for Expanding the C: Partition Power Quest has a product called Server Magic 
( They are now owned by Symantec and changed the name to Volume Manager ).

If your only expanding the data partition's you can do so with Dynamic Volumes 
in 2000 / 2003 server and then add the additional space once you have added it 
to the drive array in the controller raid utility.

Tom,

First Question.  Some of the older Compaq RAID Controllers didn't allow 
raid expansion, but all of the new models (52xx, 5i, 64xx, 6i) should 
allow this.  Check the firmware levels on the card, and also check the 
version of the PSP (ProLiant Support Pack) your running on the server. 
 From within Windows, you should be able to expand the array no 
problems.  There will be performance hit while it does it (since its 
shuffling data around), but the machine should be reasonably happy.

Second Question.  You *might* be able to extended the C: partition, but 
the requirements outlined in the Microsoft Support Article: 
http://support.microsoft.com/default.aspx?scid=kb;en-us;325590, are 
fairly stringent:

- For Basic volumes, the unallocated space for the extension must be the 
next contiguous space on the same disk (this wouldnt be do-able, unless 
you deleted the second partition before attempting the resize).
- Only the extension of data volumes is supported. System or boot 
volumes may be blocked from being extended. (well, seeing as your trying 
to extend the C: drive, this could be a problem)

Last Question, A Single Channel (scsi bus) within a controller can have 
any number of arrays consisting anywhere from a single drive, up to a 
full bus.  Its purely a logical distinction.
