Replacing a boot disk WITH LVM mirroring

As with chapter 2, mirroring adds a new twist to the recovery of a boot disk, and makes the recovery much simpler than without mirroring.

Example configuration:


Volume group /dev/vg00 contains the three disks, with the logical
 volume configuration as shown:

                 |---------|     |---------|     |---------|
                 | lvol 1  |     | lvol 1  |     | lvol 4  |
                 |         |     | mirror  |     |         |
                 |---------|     |---------|     |---------|
                 | lvol 2  |     | lvol 2  |     | lvol 5  |
                 |         |     | mirror  |     |         |
                 |---------|     |---------|     |         |
                 | lvol 3  |     | lvol 3  |     |         |
                 |         |     | mirror  |     |         |
                 |---------|     |---------|     |---------|

hardware address  52.6.0          52.5.0          52.4.0
device file       c0t0d0          c0t1d0          c0t2d0
  (/dev/dsk/)

This involves a head crash of the disk at hardware address 52.6.0.
