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:
SunOS Release 5.10 Version Generic_127127-11 64-bit

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

NAME
ciss -- HP/Compaq Smart ARRAY 5/6 RAID controllers SYNOPSIS
ciss* at pci? function ? DESCRIPTION
The ciss driver provides support for the CISS interface implemented by fifth and later generations of the HP/Compaq Smart ARRAY family of controllers. The CISS interface is defined in the document entitled CISS Command Interface for SCSI-3 Support Open Specification, Version 1.04, Valence Number 1, Compaq Computer Corporation, 2000/11/27. This driver supports several Compaq and HP controllers implementing the CISS interface, including: o Compaq Smart Array 5300 version 1 o Compaq Smart Array 5300 version 2 o Compaq Smart Array 5i version 1 o Compaq Smart Array 5i version 2 o HP Smart Array 5312 o HP Smart Array 6i o HP Smart Array 641 o HP Smart Array 642 o HP Smart Array 6400 o HP Smart Array 6400 EM o HP Smart Array E200 o HP Smart Array E200i o HP Smart Array P400 o HP Smart Array P400i o HP Smart Array P600 o HP Smart Array P800 o HP Smart Array V100 o HP Smart Array 1 through 13 These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superpositions of those configurations. Although the controllers are actual RAID controllers, the ciss driver makes them look just like SCSI controllers. All RAID configuration must be done through the controllers' BIOSes. Hardware from previous generations of this product family may be supported by the cac(4) driver. SEE ALSO
bio(4), cac(4), intro(4), pci(4), scsi(4), sd(4) HISTORY
The ciss driver first appeared in NetBSD 3.1. AUTHORS
The ciss driver was written by Michael Shalayeff <mickey@openbsd.org>, and ported to NetBSD by Tonnerre Lombard <tonnerre@netbsd.org>. BSD
