use head -2. What is the actual o/p you are looking for?

svmon | head -2

Can you try this?

Let try this ..

# cat test
#!/bin/bash
# Simple Disk Alert Script
DISKRATIO=40  # %40
for MOUNT in `df -k | awk '{print $6}' | grep -v "^Mounted"`
    do
      USAGE=$( (df -k|grep -w $MOUNT|awk '{print $5}'|awk -F% '{print $1}') )
            if [ $USAGE -gt $DISKRATIO ] ; then
                echo "On $MOUNT --  disk is usage about -- %$USAGE ratio ..."
            fi
    done

 ./test
On / --  disk is usage about -- %47 ratio ...
On /oracle --  disk is usage about -- %43 ratio ...
