• For Graphics mode - Ctrl+Alt+f7
• Enter Username and Root Password. 

  

Step-2:

• Check Mount points using - $fdisk –l

 

• Add a new partition on 1st HD using - $fdisk  /dev/hda

  

  

• Then enter Hex cod for new partition using “ t “ (for Linux LVM = 8e).
• Save this partition using “ w “.

   

Step 3:

• Do same step 2  for 2nd HD - $fdisk  /dev/hdc

  

  

• Save this settings into kernel by using - $partprobe

  

 Step 4:

• PV creation using- $pvcreate  /dev/hda11  /dev/hdc1

  

• To Display use - $pvdisplay
• Save this to kernel using - $partprobe

 Step 5:

• VG creation using - $vgcreate  oravg  /dev/hda11  /dev/hdc1  
• To Display - $vgdisplay

  

Step 6:

• To display - $lvdisplay

  

  

Step 7:

• Format this partition(/dev/oravg/oralvm) using - $mkfs.ext3  /dev/oravg/oralvm

   

Step 8:

-$df –Th

  

  

Step 9:
