Answer / deepak kumar

In SVM, get new disk and partion the new disk same as boot
disk

# prtvtoc /dev/rdsk/<> |fmthard -s - <new_disk>
# create meta with metainit command and do metattach with
all volumes

# On root partion, run metaroot command to convert it under
meta. Also need to edit /etc/system with set
md:mirrored_root_flag=1

with veritas root mirroring.

1. Iniitalize the both disk under veritas and add into root
disk group
2. once initialize, encapsulate the disk so that no data to
be lost.

3. use vxrootmir command or vxdiskadm and option 6.
