Hi,

I have a Sunfire v240 with 4 72GB internal disks (drive 0 is the system disk).

Scratch the following ( Revised requirements below)
I need to set up a Raid using the remaining 3 disks for a Oracle database, but don't know how to do it (or the size of the database). I don't know if setting up the Raid will use one of the disks as parity or not, so details would help. I've read some of the threads, but don't know which one is better, Raid 0 +1, Raid 1 + 0, or another method.

The server came pre-installed with Solaris 9 and I don't know if it came with LVM (or how to access it if it does).

Thanks in advance.

Revised info:

My customer said they want dr0(system disk) mirrored to dr1, and dr2 mirrored to dr3, instead of the Raid.

use slvm (solaris logical volume manager) to do what you want. examples are in /etc/lvm/md.tab. also you should read "man metadb" and "man metainit"...
