UNIX Log File Content - Duplication Issue

I have a shell script with 2 run time arguments. During the execution if i got any error, then it needs to redirected to a error file and in console. Also both error and output to be redirected to a log file.

Error output is getting copied to err file and getting displayed in console too. But in log file the output and error message it getting redirected twice. I am not willing to use set -x option.

Code:

#! /bin/sh
errExit ()
{
    errMsg=`cat $1.log >> "$1".err`
    cat "$1".err | tee /dev/fd/3    
   return
}
test()
{
logfile=$1
exec 3>&1 1>>"${logfile}".log 2>&1
echo "$1"
echo "$2"
echo " "
echo "#################################################"
echo "Hi Hello,This is first function"
echo "#################################################"
if [[ -z "$2" ]];
then 
errExit $logfile
return
else
#<some Commands Here>
fi
}
test_1()
{
logfile=$1
exec 3>&1 1>>"${logfile}".log 2>&1
echo "$1"
echo "$2"
echo " "
echo "#################################################"
echo "Hi Hello,This is second function"
echo "#################################################"
if [[ -z "$2" ]];
then 
errExit $logfile
return
else
#<some Commands Here>
fi
}

NAME

       line - Reads one line from standard input

SYNOPSIS

       line

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       line:  XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS

       None

DESCRIPTION

       The  line  command  copies one line, up to and including a newline, from standard input and writes it to standard output.  Use this command
       within a shell command file to read from your terminal.	The line command always writes at least a newline character.

NOTES

       The line utility has no internationalization features and is marked LEGACY in XCU Issue 5. Use the read utility instead.

EXIT STATUS

       Success.  End-of-File.

EXAMPLES

       To read a line from the keyboard and append it to a file, enter: echo 'Enter comments for the log:' echo ': c' line >>log

       This shell procedure displays the message: Enter comments for the log:

       It then reads a line of text from the keyboard and adds it to the end of the file log.  The echo  ':  c'  command  displays  a	:  (colon)
       prompt.	See the echo command for information about the c escape sequence.
