HI,rvent ,read from your post,your disk /dev/dsk/c5t8d0
Allocated PE is 9650 but the mirror one /dev/dsk/c4t8d0 Allocated PE is 9625.

what about the used 25 pe on /dev/dsk/c5t8d0

Please attach pvdisplay -v /dev/dsk/c5t8d0,
and ls -al /dev/vg01/*

from your post,i will tell you how to recreat your removed lv.Then you could remove it and repair vg01 error.
