#* AUTHOR      : James M. Santos                                         *
#* DESCRIPTION : Displays summary information about physical volumes     *
#*               (PV) together with more detailed information about each *
#*               logical volume (LV) defined in each PV.                 *
#* PARAMETERS  : 1) -p          - display output                         *
#*               2) -o filename - send the output of the script to the   *
#*                   filename specified.                                 *
#*               3) hdisk(s)    - PV name                                *
