SBS2003 + HP ML350 - New Disk Added To Raid 5 - How Do I make The Array Bigger Using This Disk

I have the following:
HP ML350 Server with hot plug disks
Originally 3 x 36.4 Disks with on partition C: - into Array A (only one array setup)
I have added 2 more disks

1 has been setup as a Hot Spare and seems ok.
The other has been added to Array A - I extended the Array (which took overnight) - using HP ACU (Array Configuration Utility)
The extension completed ok and I can see the following under MMC/Disk Management

C: 67.86Gb NTFS             |       33.92Gb                                      |
Healty (System)               |       Unallocated                                 |

Also worth noting:  The array status in ACU says "#705 Background parity initialization is currently queued or in progress on logical drive 1 (Raid 5 in Array A)

1 - What do I need to do to integrate this free space into my C: Drive?
2 - Also is the error #705 going to go away once I complete the steps in Q1?

THis is a live server so I wanted the advice from the experts before changing anything.

Hi support_realtime,

1. There should be an option Extend Logical Drive in the configuration utility.
2. Have you tried ADU to check for the error message its on the Smart CD supplied by HP.

1 I have run the Extend Logical Drive program.
  Before I ran this the new disk was added to the array but not seen as available space by the OS
  After running this the additional space was visible on the OS (on Disk Mgmt) - as unallocated (see question notes)

 I need to know what to do to integrate this unallocated space into the current c: (without affecting the current c: drive or any boot sectors)
 I'm sure that its simple, but just need guidance so I don't do something stupid on a live server.

2 Yes - no errors just the informational message "#705 Background parity initialization is currently queued or in progress on logical drive 1 (Raid 5 in Array A)"

Decided not to expand the C: drive and create a new drive D: to host the USER SHARED FOLDERS
