RAID 1 on a Mac Pro running Tiger

Hi,

I just got my new Mac Pro. It has two 500 GB drives. I had them installed with the intention of making them RAID 1 (mirroring). I thought there would be a good How-to on Apple's site about this but they don't have all that much info (at least not anything I could find).
I found one tutorial on line but it said I needed at least three disks to make this happen -- that doesn't sound right to me. As long as I'm willing to re-install the OS, just two disks seems fine. Is this correct?

Also, can someone tell me how I go about doing this? I assume I boot from the CD and somehow or another select RAID, but I can't find where I would do that?

G'day,

Booth of the CD and select RAID, then from the left hand side just drag in the drives that you wish to run the raid no. Click create and make sure is RAID 1, done.

Hi AM,

Thanks, but I did boot off the CD. I don't see anyplace to select RAID from? Is it so obvious that I just missed it?

Thx,

G'day,

Have you boot of a 10.4 CD?
check this link out from apple support.

Let me know how you go.

Cheers,

The missing piece to this puzzle for you may be as simple as your finding Disk Utility up in the system menus (I believe it's the "Installer" menu) once you've booted from the CD and are looking at the initial screen of the installer. Once you have launched Disk Utility from the menu, follow the steps found at the link below.

PeterD, Yes! That was the missing piece of the puzzle. Finding Disk utility when I started from the CD.

I found it and I'm ready to proceed.


One more question.
Which Volume format should be used.  OS Extended (Journaled) or just OS Extended?
Just for comparison sake, I looked at the machine I'm currently on (not the one I want to set RAID up on) and it says  it's OS Extended.  Is the "Journaled" option good?

Thanks,
Mike

G'day,
Use OS Extended (Journaled) it helps if you force reboots. The Journaled version is good.

Hope this helps,

Cheers,
