Script to scan the disks and make file system

Hi
What I'm trying to do(manually) is logging into the server
and running the below mentioned commands

Code:

ls /sys/class/scsi_device/ | while read i; do echo "- - -" > /sys/class/scsi_device/$i/device/rescan;done

lsblk
echo -e "o\nn\np\n1\n\n\nw" | fdisk /dev/sdd
partx -a /dev/sdd1
mkfs.ext4 /dev/sdd1
blkid  /dev/sdd1 | awk '{print $2}' | cut -d "\"" -f2
Finding the blkid of the disk and updating the /etc/fstab
echo "UUID=$(blkid -s UUID -o value /dev/sda1)" /root/abcd  ext4 defaults 0 0 >> /etc/fstab

so i have to do this on multiple machines logging into each machine
scanning for new disk where the disk may be any (/dev/sdg /dev/sdb or /dev/sdi like wise but the newly added disk will be of 6G
so though of writing simple shell script but a little mistake can mess up the whole thing here i need to partition only the disk which i have scanned and has been added recently otherwise i may loose the data
i thought of something like this

Code:

ls /sys/class/scsi_device/ | while read i; do echo "- - -" > /sys/class/scsi_device/$i/device/rescan;done
b=$(lsblk | grep 6G|awk '{print $1}')
echo -e "o\nn\np\n1\n\n\nw" | fdisk /dev/$b
partx -a /dev/$b
mkfs.ext4 /dev/$b1
echo "UUID=$(blkid -s UUID -o value /dev/$b1)" /root/abcd  ext4 defaults 0 0 >> /etc/fstab

Please suggest me the best way to do this.

NAME

       script-email - Amanda script to send email notifications

DESCRIPTION

       script-email is an Amanda script implementing the Script API. It should not be run by users directly. It sends a notification email to the
       addresses specified in the MAILTO property.

PROPERTIES

       This section lists the properties that control script-email's functionality. See amanda-scripts(7) for information on the Script API,
       script configuration.

       MAILTO

	   List of email addresses that will receive an email on command execution. It is a multi-valued property:
	     property "MAILTO" "amanda@domain.com" "sysadmin@domain.com" "amandauser@domain.com"

EXAMPLE

       In this example, script-email is scheduled to be run before the DLE, on the server.  The unqualified email address amanda will be passed to
       the email system unchanged.  The script is then attached to a dumptype, which can then be specified for any DLEs which require
       notification.
	define script-tool pre-email {
	  comment "email me before this DLE is backed up"
	  plugin  "script-email"
	  execute-on pre-dle-backup
	  execute-where server
	  property "mailto" "amanda"
	}

	define dumptype user-tar-email {
	  user-tar
	  script "pre-email"
	}
