Re: pv unavailable
#pvchange -a n /dev/disk/disk26
replace the disk
#vgcfgrestore -n vg00 /dev/rdsk/
#vgchange -a y vg00 -->resync mirrors
#lvlnboot -R vg00 -->update BDRA
#lvlnboot -R vg00 -->check the boot configuration.
Check if all the mirrors are in sync.
# vgdisplay -v vg00 |egrep -i "lv name|lv status"

Re: pv unavailable
PV Name /dev/disk/disk26
PV Status unavailable
and the NO_HW status indicates a dead disk that needs replacement.
Hope this helps!
Regards
Torsten.
