I have written a scipt that will report when a drive is down, but i finding if the status of the drive is UP, then "while read LINE" ignores the IF statement. I want the script to print the echo "All the drives are up". How can i modify the script so that else exception is not ignored. vmoprcmd command give you the following output as show below: Drv Type Control 0 hcart2 DOWN-ACS 1 hcart2 DOWN-ACS vmoprcmd | grep -i DOWN | awk '{print $1,$3}' | while read LINE do if [ $LINE != "" ];then .......... else echo "All the drives are up" >> /tmp/drive_status fi done ..... Thanks Junes King Regards Junes

Your problem is that if all the drives are up nothing is grepped and, thus, your while loop never executes. I don't use the vmoprcmd, so I placed the output in file prcmd.txt. If the word "DOWN" isn't found, the grep fails setting the unix exit code to non-zero meaning all the drives are up: #!/bin/ksh grep -i "DOWN" prcmd.txt > myfile.txt if [ $? != 0 ] then echo "All the drives are up" fi # end script. Now, if the myfile.txt size is greater than 0, you have a problem drive: if [ -s myfile.txt ] then echo "Process myfile.txt to find the bad drive" fi

Thanks for that, it worked a treat!! if [ -s myfile.txt ] then echo "Process myfile.txt to find the bad drive" fi King Regards Junes
