ServeRAID-5i - How do I create ONE logical drive from 6 physical drives?

I have an IBM xSeries 345 Type 8670 Server with a ServRAID-5i Ultra320 SCSI Controller.  I literally ran out of space on C:\ and had lots of space on D:\ for all my data.  After backing up only the data files and moving them to another server, I decided to format.  Need to get it back up and running, but ran into a problem.  (Let me add... I would like to not have 2 drive letters this time.... want just one large c: drive)
I started out with the ServerGuide6.1.3  Setup and Installation CD, ran through the wizard, Express Config for RAID which created... 1 Logical Drive, RAID level 5, Array A, Hot Spare Yes, only 1 controller.  Express Config did see my 6 physical drives, took 5 added them together and took 1 for hot spare drive so I excepted the way it looked and made no changes.  Applied, removed CD, put in my Windows 2003 Server CD, was looking good until it asked me where I wanted to install with one option being C:\ 55MB free space ... Ouch!  Not what I expected.
I plan to try again, but not comfortable using RAID and not sure why my one drive came out so small.
I want all space usable and one logical drive of C:\
Can you please help me to get one large C:\ drive?

The array CD will allow one create a partition, in that partition one can create a logical drive which would end up being the C:.

What size are the disks?  One should see ~ 4*drive capacity (Raid 5 of 5 disk + hot spare).

Each disk is 36.4GB
Physical drives in Array A - SCSI channel 1 - New Online CH1, ID 1 (34715MB)
Then it expands down to say New Online CH1, ID 2 (34715MB); ID 3 on down to ID 5.
Logical drives in Array A - New logical drive 1 (133860MB)New hot-spare Ch1, ID 0 (34715MB)
I am asked the question of click 'Continue' to work with your ServeRAID configurations or click 'Exit' to exit the ServeRAID Manager program & return to ServerGuide.
I am not seeing where I would go to create the partition??
The wizard says that once I partition & format these drives, I can use them to store data....but not seeing where that is.  THX!!

Clicked Exit to return to the ServerGuide, system reboots, attempts to boot to CD and continue to read, and goes in a cycle of rebooting, not taking me to the next step in the ServerGuide.
Gosh...I wonder if it would help to try another CD that came with another identical server?
Yep!!  Second CD worked like a charm.  I got to the next step of partitioning the logical drive, used up all the space I wanted to use and was able to move on from there.
Sorry to have taken up your time on a bad CD.

2nd CD worked like a charm and gave me the option to create one logical drive in this partition.  Your question made me question my 1st CD and I couldn't see why it would not take me to the next step to partition.  THX!!
