Script for identifying multiple disks on a Linux server

This is a short script for identifying 3 PAR disks allocated to a physical server running Linux with multipathing enabled.

Put the disk WWN details provided by the SAN admin in a file called detail.txt.

Now run the following for loop to extract the mpath devices corresponding to the disk WWNs.

#!/bin/bash

for i in `cat detail.txt | awk '{print $3}' |  egrep -v 'showvlun|VV_WWN' | uniq -u`

do

echo "corresponding to 

 `cat detail.txt | awk '{print $3}' |  egrep -v 'showvlun|VV_WWN' | uniq -u | grep -i $i` disk is 
  `multipath -ll | grep -i -A1 $i |awk '{print $1}'` "
  
done

The output of the script is as follows:

 60002AC00000000000004BD20000935D disk is
