Hardware RAID using three disks

Dear All ,

Pl find the below command ,

Code:

# raidctl -l
Controller: 1
        Volume:c1t0d0
        Disk: 0.0.0
        Disk: 0.1.0
        Disk: 0.3.0
# 
 raidctl -l c1t0d0
Volume                  Size    Stripe  Status   Cache  RAID
        Sub                     Size                    Level
                Disk
----------------------------------------------------------------
c1t0d0                  136.6G  N/A     OPTIMAL  OFF    RAID1
                0.0.0   136.6G          GOOD
                0.1.0   136.6G          GOOD

AVAILABLE DISK SELECTIONS:
       0. c1t0d0 <LSILOGIC-LogicalVolume-3000 cyl 65533 alt 2 hd 16 sec 273>
          /pci@0/pci@0/pci@2/scsi@0/sd@0,0
       1. c1t3d0 <SUN600G cyl 64986 alt 2 hd 27 sec 668>
          /pci@0/pci@0/pci@2/scsi@0/sd@3,0
Specify disk (enter its number): ^D

In the above output , i want to know how this RAID 1 volume has been created , whether it is created of two disks or three disks as because i find in "raidctl -l " command there are three disks present .

And also i want to do the patching on this server , any one tell me how to split this raid 1 volume and do the activity.
