Disk Structure Command for ASM - asmdisks

In my firm we have a seperation between System guys to the DBAs, we don't have root privileges. this is the reason that they are peparing us the ASM disks.
After using "/etc/init.d/oracleasm createdisk..." I tailored a script to see all the information that I can get WITHOUT the need to connect to the ASM instance.

#!/bin/ksh

export ORACLE_HOME=`grep ASM /etc/oratab | cut -d: -f2`
export PATH=$PATH:~$user/dba/scripts/bin:$ORACLE_HOME/bin
export SID=`grep ASM /etc/oratab | cut -d: -f1`

printf "\n%-15s %-14s %-11s %s\n" "ASM disk" "based on" "Minor,Major" "Size (Mb)"
printf "%-15s %-14s %-11s %s\n" "===============" "=============" "===========" "========="
for i in `/etc/init.d/oracleasm listdisks`
do
v_asmdisk=`/etc/init.d/oracleasm querydisk $i | awk '{print $2}' | sed 's/\"//g'`
v_minor=`/etc/init.d/oracleasm querydisk $i | awk -F[ '{print $2}' | awk -F] '{print $1}' | awk '{print $1}'`
v_major=`/etc/init.d/oracleasm querydisk $i | awk -F[ '{print $2}' | awk -F] '{print $1}' | awk '{print $2}'`
v_device=`ls -la /dev | awk -v v_minor=$v_minor -v v_major=$v_major '{if ( $5==v_minor ) { if ( $6==v_major ) { print $10}}}'`
v_size=`${ORACLE_HOME}/bin/kfod asm_diskstring='ORCL:*' disks=all | grep ${v_asmdisk} | awk '{print $2}'`
Total_size=`expr $Total_size + $v_size`
printf "%-15s %-14s %-11s %s\n" $v_asmdisk "/dev/$v_device" "[$v_minor $v_major]" $v_size
done
printf "\nTotal: %43s\n\n" $Total_size

The output is:
