Show rootdg information
-bash-3.00# vxprint -g rootdg
Disable plex (rootvol and swap vol)
-bash-3.00#vxedit -g rootdg dis rootvol-02 swapvol-02
Remove plex (rootvol-02 swapvol-02)
-bash-3.00# vxedit -g rootdg -rf rm rootvol-02 swapvol-02
Check the status
-bash-3.00# vxprint -g rootdg

Answer / sbrahman75
First disaccociate the plex
#vxplex dis rootvol-02
Now, the slice information for disk newroot (c2t2d0) is:
# prtvtoc -s /dev/rdsk/c2t2d0s2
Delete the rootalt volume from the new root disk.
# cd /
# umount /mnt
# vxvol stop rootalt
# vxplex dis rootvol-02 (Disassociate the plex from the
volume and remove the volume.)
# vxedit rm rootalt
# vxsd dis newroot-01 (Disassociate the sub-disk from the
plex and remove the plex.)
# vxedit rm rootvol-02
7. Mirror all the other volumes from the current root disk
to the new root disk.Do not mirror swap volumes. Swap slices
will be created on the new disk manually. In this example,
the volumes to mirror are var and opt.
# vxassist -g rootdg mirror var newroot
# vxassist -g rootdg mirror opt newroot
