As others have stated the while loop is run in a subshell and variable assignments are lost the general accepted solution is to use Process Substitution eg:

Code:
    while read VGNAME
    do
        PPSTRG=$(lsvg ${VGNAME} | awk -F: '/PP SIZE/ {print $NF}')
        ...
    done < <(lsvg | grep -v rootvg)
    ...
