bash scripting: using multiple 'for loops'??
Hey guys,

I'm kinda a noob at scripting. I am trying to create a script that uses multiple for loops with the lsiutility to monitor disk health on a system.
The script runs, but it will continually echo an infinite number of LogVolumes when there are only 2 per virtual disk on my server. It's probably something simple. Any sugguestions?

Code:
#!/bin/bash
IFS=$'\x0A'
num_virt_disk=`/usr/bin/lsiutil -p -a 0|grep 'MPT Port found'|awk '{print $1}'

for ((i=1; i<=$num_virt_disk; i++))
do
	num_log_vol=`/usr/bin/lsiutil -p${i} -a 1,21,1,0,0,0|grep volume|awk '{print $1}'`

for ((x=0; i<=$num_log_vol; x++))
	state=`/usr/bin/lsiutil -p${i} -a 1,21,3,0,3,1,0,0,0|grep State|awk '{print $3}'|sed 's/,//g'`

        if [ "$state" = "optimal" ]
        then
                echo -e "OS|Linux|Disks|VirtualDisk${i}|LogVolume${x}|Status\t0\t0\t"
        else
                echo -e "OS|Linux|Disks|VirtualDisk${i}|LogVolume${x}|Status\t1\t2\t"
        fi
done
done

gst-complete-0.8

gst-complete-0.8(1)						   User Commands					       gst-complete-0.8(1)

NAME

       gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines

SYNOPSIS

       complete -Cgst-complete-0.8 gst-launch

       gst-complete [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
       gst-launch command lines.

       You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.

       gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
       complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.

OPTIONS

       The following options are supported by gst-complete-0.8 and gst-complete:

       --help	       Display detailed usage message. You can also use -? to specify this option.

       The following options are supported by gst-complete only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

EXAMPLES

       Example 1: Generating the Registry of Available Plugins by Running gst-compprep

       Run the following command in your .bash_profile or other appropriate place:

       example% complete -C gst-complete-0.8 gst-launch

       Example 2: Running the Wrapper Script and Displaying the Command Name

       example% gst-complete --print
       /usr/bin/gst-complete-0.8

FILES

       The following files are used by this application:

       /usr/bin/gst-complete-0.Executable for bash completion for gst-launch

       /usr/bin/gst-complete   Wrapper script that runs the latest installed version of gst-complete-X.X
