The generation 5 and 6 controllers auto configure.
So if you don't do anything, at the first power on.
1 disk it will create a RAID 0
2 disks it will create a RAID 1
3 disks it will create a RAID 5
More disks than that, I don't know how it configures.
When you create a RAID you will end up with 1 or more LUN's (Logical Units). The LUN(s) appear as a physical disk to the Oprating system.
The auto config create only 1 LUN, using the number of disks available.
If you have only 1 controller, it will be set for boot controller.
If you have more than 1 controller, one of them will be set as boot controller, I can't remember the rules.
If you add in disks later, the array controller will do nothing. You will have to configure it manually.
There is 2 parts in a RAID disk.
1. The Array: Here you select wich disks will be used for an array.
2. The LUN: Here you select the size of the LUN(s) and RAID level(s)
You got 2 configuration tools
1. ORCA (Option ROM Configurable Adapter), the simple tool. During POST you hit F8, when prompted by the array controller. It's simple and easy.
Create Array: including use of hot spare disk. Multible arrays, only 1 LUN on each array.
Delete Array: Delete your data, non reverseble.
View Array
Select as boot controller: Only appear if controller isn't set as boot controller.
2. ACU (Array Configuration Utility).
The tool, that enable you to use all of the features of the Smart Array controller.
You can expand, extend exsisting arrays, change RAID level (Migration), mulible LUN's on the array(s), different RAID levels within an array.
You can do everything on-line = Server in production.
If you have installed your server, using Smart Start, the ACU is installed.
It take 2 actions to start ACU.
Start the engine
Start ACU
Both done from: all programs > HP system tools > array configuration utility (Might not be exact)

Now You are confusing me. And I do hope you havn't got yourself into trouble.
I wasn't aware that it's possible to do a migration from the ORCA.
I did believe it was possible from the ACU only.
Migration is normally no problem.
Can you please tell what you want to do?
As I understand:
You have got 1 disk, and you want to put in another disk, and create a mirror = RAID 1.
Yes HP does call it 0+1, no matter.
If that's what you want, then I Woould recommend using the ACU.
Server should be running.
1. Hot add disk.
2. open ACU.
3. Expand array, press save.
4. Wait till the next day.
5. Migrate RAID level, from 0 to 0+1
6. next day it will be finished.
I am afraid, You have been trying to create a new array, using the disk that is allready
in use and installed. If you do that I am afraid you might have deletet your installation.

Ok. So you want to install a server, with 2 hard drives, each 36 GB. And you want to create one 72 GB disk (RAID 0, no redundency).
As a wrote. The Smart Array controller auto configure a RAID 1 (Mirror) when you got 2 unconfigured drives.
There is 2 ways to configure it as you want.
1. The ORCA. Hit F8 when prompted.
2. Select Create array.
3. Select Both hard drives.
4. Selecet RAID 0
5. Boot on Smart Start and install your server.
Or You can use ACU, from the Smart Start CD.
1. When the Smart Array Controller pormpts you to Hit F8 or ESC, Hit ESC, this will abort the auto configuration.
2. Boot from the smart start CD.
3. Select the Maintenance Tab (I'm not 100% sure if it call maintenance, so look for something like that)
4. Start the ACU.
5. Create a RAID 0.
6. Continue Installation from Smart Start.
In Your case, it seems lik you have got it auto configured.
If so, you must delete the RAID. The fastet way is to use the ORCA.
If you miss a boot controller, simpy check the first screen on the ORCA.
If you got a fourth line: Select as boot Controller, then select that line and hit enter. Follow any on-screen instrauction. And the fourth line will disappear, wich means the controller is now boot controller.
Normally if you got, one controller only, it will be selected automaticly.
Iy's possible to have serveral Controllers in a server, then you may have to choose manually. Each controller then will prompt you to hit F8.
The most importen remember is: If you have got an unconfigured Smart Array, Genration 5 or 6, it will auto config., according to the rules I wrote.
The RAID will be avaiable instantly, after it has been configured.
During Smart Start you will be asked to select the size of your C-drive. I'm not sure at what point, but take your time, nothing will time out. Except for the first time autoconfigure.
In case you don't know: Beware with RAID 0, you have got no redundacy, wich mean if one drive fail, you must re-install/Restore from backup.
Just ask all the questions you need.
Cheers
