1. Open Oracle Virtual Box Manager
2. Select shutdown virtual machine like ( RAC01 VM)
3. Goto Setting option
4. Storage option select add hard disk
5. define name & size of disk.
6. reboot machine
7. Login as root
Run this command and make note of the sdx entries

Once rebooted you should see you have an unpartitioned hard-drive ready to go. To check this run from the terminal:

Disk /dev/sde doesn't contain a valid partition table
[root@rac01 dev]#
To fix this we need to first partition the new drive.
[root@rac01 Desktop]# fdisk /dev/sde
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xc8f14ebc.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

Good so we now have a partition at /dev/sde that we can now format with our chosen filesystem.
To do this run:
[root@rac01 Desktop]# mkfs -t ext4 /dev/sde
mke2fs 1.41.12 (17-May-2010)
/dev/sde is entire device, not just one partition!

Great, now all we need to do is mount our fresh filesystem. In my case I'm going to mount it at
/home as I've already moved the original /home directory out of the way.[root@rac01 Desktop]# mount /dev/sde /home
