You are right erman.We are able to get the output of scsi_id -g -u -d /dev/sdb.Then we have identified the issue with the script

Original script

[root@erpproddb1 ~]# cat a.sh
#!/bin/ksh -x
for disk in `ls /dev/sd*`
do
disk_short=`basename $disk`
wwid=`/usr/lib/udev/scsi_id -g -u -d /block/$disk_short`
if [ "$wwid" != "" ]
then
  echo -e "Disk:" $disk_short "\tWWID:" $wwid
fi
done


Modified script

[root@node1~]# cat a.sh
#!/bin/ksh -x
for disk in `ls /dev/sd*`
do
disk_short=`basename $disk`
wwid=`/usr/lib/udev/scsi_id -g -u -d /dev/$disk_short`
if [ "$wwid" != "" ]
then
  echo -e "Disk:" $disk_short "\tWWID:" $wwid
fi
done

and now,with modifed script,we got what we are expecting as below

[root@erpproddb1 ~]# sh a.sh
