Thanks to Will Sterling, Michael Horton, Brian Ackerman, Yother Andy and

Probably it is not supported by Sun, but you can still boot from A5200 as
long as you can see drive from Ok prompt

I will try to boot from A5200 during maintenance window.

Here is what I did

# /usr/lib/vxvm/bin/vxdisksetup -i c2t106d0

# vxdg -g rootdg adddisk disk01=c2t106d0       ( make sure this is added as
a sliced)
# /etc/vx/bin/vxrootmir disk01
At this time, I have followinh config.

# vxdisk list

c0t0d0s2     sliced    rootdisk     rootdg       online
c0t1d0s2     sliced    root_mirror  rootdg       online
c2t106d0s2  sliced    disk01       rootdg       online

*# vxassist -g rootdg mirror swapvol disk01       *

Verify using the vxprint command.
Verify that you have proper OpenBoot PROM Parameters set

*# eeprom nvramrc
*nvramrc=devalias vx-rootdisk /pci@1f,4000/scsi@3/disk@0,0:a
devalias vx-disk01 /pci@1f,4000/SUNW,ifp@4/disk@w21000004cf68507e,0:a
devalias vx-root_mirror /pci@1f,4000/scsi@3/disk@1,0:a
OK, boot rootdisk
OK, boot root_mirror
OK, boot disk01

I will try it on maintenance window and let you know.
