how to hardware RAID 1 on T5120

Hi,

I have t5120 sparc and I have 2 146 G drives in the system. I will be installing solaris 10 and also want the system mirrored using Hardware RAID "1"

The System did come preinstalled as it comes from sun. I did not do much on it.

I booted system using boot cdrom -s

gave format command

it showed disks below,

# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
0. c1t0d0 <SUN146G cyl 14087 alt 2 hd 24 sec 848>
/pci@0/pci@0/pci@2/scsi@0/sd@0,0
1. c1t1d0 <SUN146G cyl 14087 alt 2 hd 24 sec 848>
/pci@0/pci@0/pci@2/scsi@0/sd@1,0
Specify disk (enter its number): ^D


then I tried below, I wonder if the output is normal ?

# raidctl
Controller: 1
Disk: 0.0.0
Disk: 0.1.0


I was expecting below

# raidctl
No RAID volumes found.



Anyways, from the position , system is in, how to configure RAID 1 and I will be installing the Solaris 10 again with repartitioning according to my needs, ( I do not mind destrying the disk data)

I tried raid1 using raidctl command earlier and it showed some errors

Boot device: /pci@0/pci@0/pci@1/pci@0/pci@1/pci@0/usb@0,2/storage@2/disk@0:f File and args:

WARNING: /pci@0/pci@0/pci@2/scsi@0/sd@0,0 (sd0):
Corrupt label - bad geometry

Label says 286718976 blocks; Drive says 286607360 blocks



and
then when I tried to install solaris 10 after earlier config of RAID 1 there was below error,

After saying NO to remote services

One or more disks are found, but one of the
following problems exists:

Hardware failure
Unformatted disk.


I have then deleted RAID Volume and rebooted system to see the same system disk set up as original.

Please let me know how to proceed from above setup

Thanks
