Thanks to Torsten and Tom Lieuallen for replying -

Some disk background:
The T2000s come with 2 SAS internal drives 0 1 .  SAS is serial attached
SCSI; like SATA serial ATA. Just remember that parallel drives send data in
parallel down the EIDE ribbon; while serial is a single data path and is
much faster and more reliable.
SAS is more reliable and supports a much higher rpm drive than SATA..

Before anything we'll need to apply the firmware patch to the LSI raid/SAS
and it wouldn't be a bad idea to install the firmware for the SC -

First thing we need to drop down to the OK prompt ha create our mirror (we
could also boot net)

uadmin 2 0 - will sync the filesystem and bring the server to the OK prompt
- you could do a shutdown -y -g0 -i0 now for a cleaner init shutdown..

# uadmin 2 0
syncing file systems... done
Program terminated
{14} ok

Wanted to go into the SC controller or could do (ok setenv auto-boot? false)
#. will get you to the sc prompt.

sc> bootmode bootscript="false to autoboot? tru to fcode-debug?"
sc> poweron -c
The Host System Power is already running
sc> console -f
Enter #. to return to ALOM.
 {14} ok printenv

boot-command            boot                           boot

As you can see autoboot is set to false. We need to select the device path
to our 2 internal SAS drives. Remove the disk at the end..

ok show-disks
a) /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/disk
b) /pci@7c0/pci@0/pci@1/pci@0/ide@8/cdrom
c) /pci@7c0/pci@0/pci@1/pci@0/ide@8/disk
Enter Selection, q to quit: a
/pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/disk has been selected.
Type ^Y ( Control-Y ) to insert it in the command line.
e.g. ok nvalias mydev ^Y
         for creating devalias mydev for /pci@7c0/pci@0/pci@1/pci@0
{14} ok select /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2
{14} ok 0 1 create-im-volume
Target 0 size is 143243264 Blocks, 73 GB Target 1 size is 143243264 Blocks,
73 GB The volume can be any size from 1 MB to 69943 MB What size do you
want?  [69943] Volume size will be 143243264 Blocks, 73 GB PhysDisk 0 has
been created for target 0 PhysDisk 1 has been created for target 1 Volume
has been created {14} ok show-volumes Volume 0 Target 0  Type IM (Integrated
  Degraded  Enabled  Resync In Progress
  2 Members                                         143243264 Blocks, 73 GB
  Disk 0
    Primary  Online
    Target 4        FUJITSU MAV2073RCSUN72G 0301
  Disk 1
    Secondary  Online  Out Of Sync
    Target 1        FUJITSU MAV2073RCSUN72G 0301
{14} ok

So we select location 0 and 1 to create a mirror volume..
Format now see the 2 drives as one.

      2. c2t0d0 <LSILOGIC-LogicalVolume-3000 cyl 65533 alt 2 hd 16 sec 136>

You will need to reinstall the OS:
ok>boot cdrom
Only Solaris 10 is supported on the T2000. Once you have installed the OS,
several patched are required for the T1 multicore chip.
