need help to unmount file systems via script

[Maaz]

cat /proc/mounts | grep "/dev/disk/by-path/ip-"

/dev/disk/by-path/ip-192.168.0.206:3260-iscsi-iqn.2009-03.com.test:0ad96cc0-32f7-4804-a73c-11505b43db90-lun-0-part1 /ap_logs reiserfs rw 0 0

I want to write a script that unmounts all of the iSCSI LUNS


#!/bin/bash

cat /proc/mounts | grep "/dev/disk/by-path/ip-"
if [ "$?" == "0" ]
then echo "iSCSI LUNS are mounted...Unmounting all of the mounted iSCSI LUNS"
############################################
## here I need forum's help(script code), I
## mean how I can unmount all of the mounted
## iSCSI LUNS
############################################
else echo "iSCSI LUNS not mounted"
fi

Hi,
I don't have iscsi, but in fstab or /proc/mounts you have the mount point in position 2, so why not something like
for i in `cat /proc/mounts | grep "/dev/disk/by-path/ip-" | awk '{ print $2 }'
do
umount $i
if [ "$?" == "0" ]
then
echo "iSCSI LUNS umounted"
fi
done
