#Get the SCSI host# 
ls /sys/class/scsi_host

#Send a SCSI host rescan request; replace host# with the result above
echo "- - -" > /sys/class/scsi_host/host{{put the scsi host number here}}/scan
#Verify that the second disk /dev/sdb shows up with specified size
fdisk -l
#Create a single partition for the drive
fdisk /dev/sdb

      #Create a new partitition
      n
      
      #Primary partition
      p

      #Partition #1
      1
      
      #First cylinder = 1
      <RETURN>

      #Last cylinder of drive = the rest of the drive
      <RETURN>

      #Print the partition table to verify      
      p

      #Write the table to disk
      w

#Format the drive with ext3 filesystem
mkfs.ext3 /dev/sdb1

#Create mount point
mkdir /mnt/backup

#Add the following line to /etc/fstab
/dev/sdb1      /mnt/backup    ext3    defaults       1 2
