Step 5. Reboot from your new VxVM root disk. If you created a mirrored root disk, then there is nothing more
to do. The LVM root disk can now safely co-exist with your VxVM root disk, giving you an
emergency backup boot target.
Step 6. If you wish, you can convert your original LVM root disk into a mirror of your VxVM root disk using
the following commands:
# /etc/vx/bin/vxdestroy_lvmroot -v c2t0d0
# /etc/vx/bin/vxrootmir -v c2t0d0
Once this operation is complete, you will be running on a completely mirrored VxVM root disk.
Step 7. If you later choose to return to an LVM root, you can use the vxres_lvmroot (1M) command to restore
the LVM root disk.
