I found some information on this site, just want to cover my bases before doing it on our production system:
prtconf -vp|grep bootpath
root@discus2 # prtconf -vp|grep bootpath
bootpath: '/ssm@0,0/pci@18,700000/pci@1/SUNW,isptwo@4/sd@0,0:a'

nvramrc=devalias vx-disk01 /ssm@0,0/pci@18,700000/pci@1/SUNW,isptwo@4/sd@1,0:a #vx-disk01 is alternate boot disk
devalias vx-rootdisk /ssm@0,0/pci@18,700000/pci@1/SUNW,isptwo@4/sd@0,0:a #vx-rootdisk is primary boot disk

# Only comment out the following entries

set vxio:vol_rootdev_is_volume=1
umount /mnt
reboot server in single user mode
apply patches
validate if everything goes smoothly, then:
vxdiskadm option 6
source disk rootdisk
target disk disk01
otherwise:
make changes in /etc/vfstab to reflect slices of vx-disk01
boot from vx-disk01(disk01)
encapsulate disk
mirror disk using vxdiskadm
