APPENDIX A
Determine which logical volumes spanned onto that disk. You only need to recreate and restore data for the volumes that actually touched that disk. Other LVs in the volume group are still OK.

        # pvdisplay -v /dev/dsk/c0tXd0
will show a listing of all the extents on disk lu X, and to what logical volume they belong. This listing is fairly long, so you might want to pipe it to more or send it to a file. For our example:

        # pvdisplay -v /dev/dsk/c0t2d0 | more
        .....
        .....
        --- Distribution of physical volume ---
        LV Name            LE of LV  PE for LV
        /dev/vg00/lvol5    50        50
        /dev/vg00/lvol6    245       245
        .....
        .....
From this we can see that logical volumes /dev/vg00/lvol5 and /dev/vg00/lvol6 have physical extents on this disk, but /dev/vg00/lvol1 through /dev/vg00/lvol4 don't. So, we will need to recreate and restore lvol5 and lvol6 only.

NOTE: Even though lvol5 was also in part on another disk drive, it will need to be treated as if the entire lvol was lost, not just the part on c0t2d0.
