I am having a problem where I am doing a double read of 2 file and it kicks me out after it performs the first read of both files.

What I need it to do is continue to do the reads of both files.
Read the first file line 1, then go through the second file and read all lines, then go back to the first file read line 2, then go through the second file and read all line, and so on and so on

Here the code thanks in advance for your help

while read VDISKINFO
do

#GATHER VDISK INFORMATION
vdisk_id="$(echo $VDISKINFO | cut -d: -f1)"
vdisk_name="$(echo $VDISKINFO | cut -d: -f2)"
vdisk_iogrp="$(echo $VDISKINFO | cut -d: -f3)"
vdisk_status="$(echo $VDISKINFO | cut -d: -f5)"


# Read host name from tempfile if one exists
while read hostname
do

if [ "$(echo $hostname| cut -d: -f4)" = $vdisk_id ];
then
vdisk_host="$(echo $hostname | cut -d: -f2)"

if [ $nodeid -eq $preferred_node_id ];
then
printf "$format" $vdisk_host $vdisk_name $vdisk_id $vdisk_iogrp $preferred_node_id $vdisk_mdiskgrp_id $vdisk_uid $vdisk_status >> ${tempRPTfile}
(( numvdisks = numvdisks + 1 ))
fi

if [ $nodeid -eq "99" ]; #User select verified with vdisk
then
printf "$format" $vdisk_host $vdisk_name $vdisk_id $vdisk_iogrp $preferred_node_id $vdisk_mdiskgrp_id $vdisk_uid $vdisk_status >> ${tempRPTfile}
(( numvdisks = numvdisks + 1 ))
fi

fi
done < ${tempfile}


if [ $vdisk_host = "-------" ];
then
if [ $nodeid -eq $preferred_node_id ]
then
printf "$format" $vdisk_host $vdisk_name $vdisk_id $vdisk_iogrp $preferred_node_id $vdisk_mdiskgrp_id $vdisk_uid $vdisk_status >> ${tempRPTfile}
(( numvdisks = numvdisks + 1 ))
fi

if [ $nodeid -eq "99" ]; #User select verified with vdisk
then
printf "$format" $vdisk_host $vdisk_name $vdisk_id $vdisk_iogrp $preferred_node_id $vdisk_mdiskgrp_id $vdisk_uid $vdisk_status >> ${tempRPTfile}
(( numvdisks = numvdisks + 1 ))
fi

fi

done < ${tempVDISKfile}

Please modify your script to use CODE tags to maintain spacing and indenting. This makes it much easier to review.
After pasting your script to the window, highlight it all and then click the # on the icon bar above.

Now, the following shows that nesting does work:

Code:

> cat file22
1 6 4 8 2 3
2 1 9 3 2 1
3 3 5 6 3 1
4 9 7 8 2 3

> cat file22m
22m line1
22m line2
22m line3

> cat nest_22
while read mydat
  do
  echo mydat=$mydat
  while read nextdat
     do
     echo nextdat=$nextdat
  done <file22m
done <file22

> nest_22
mydat=1 6 4 8 2 3
nextdat=22m line1
nextdat=22m line2
nextdat=22m line3
mydat=2 1 9 3 2 1
nextdat=22m line1
nextdat=22m line2
nextdat=22m line3
mydat=3 3 5 6 3 1
nextdat=22m line1
nextdat=22m line2
nextdat=22m line3
mydat=4 9 7 8 2 3
nextdat=22m line1
nextdat=22m line2
nextdat=22m line3

Your right, I actually had another line in there that I took out before I posted it. It was calling another program to get more information. That line was forcing it to jump out of the loop. It was a command line to get information from an IBM San Volume Controller.

This was the line omitted. Once I took the line out in the code it ran fine. Now I just have to figure out how to get this information while still in the read.

preferred_node_id="$(${svcinfo} lsvdisk -delim : $vdisk_id | grep preferred_node_id | cut -d: -f2) "
