NOTE The boot, root, and swap logical volumes must be done in exactly the
following order to ensure that the boot volume occupies the first
contiguous set of extents on the new disk, followed by the swap and
the root.
The following is an example of mirroring the boot logical volume:
# lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c4t6d0
The following is an example of mirroring the primary swap logical
volume:
# lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c4t6d0
The following is an example of mirroring the root logical volume:
# lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c4t6d0
5. Update the boot information contained in the BDRA for the mirror
copies of boot, root and primary swap.
# /usr/sbin/lvlnboot -b /dev/vg00/lvol1
# /usr/sbin/lvlnboot -s /dev/vg00/lvol2
# /usr/sbin/lvlnboot -r /dev/vg00/lvol3
6. Verify that the mirrors were properly created.
# lvlnboot -v
The output of this command is shown in a display like the following:
