create shared disks (vdi) on Virtualbox for ASM - vboxmanage command line

                                        vboxmanage command line 

For our scenario :

Lets create shared disks (vdi) on Virtualbox for ASM setup. 

If you are getting error like below make sure you have virtual-box set in your environmental path:

In my case I have to add "C:\Program Files\Oracle\VirtualBox\" to my path. To add it to your environmental path goto :

Startup >> computer (right click) >> properties >> advanced system settings >> environmental variables >>  

1. Click on start
2. Right click on Computer
3. Click Properties
4. Click Advanced system settings
5. Click Environment Variables
6. Go to system variables
7. find Path and edit it
8. add your file location at the end of the box.

Add your virtual box installed path, usually c\programe files \ oracle

Now test the vboxmanage cmd :

You will get something like this if you have any virtual machines created.

Microsoft Windows [Version 6.1.7601]

C:\Users\arvind>vboxmanage list vms
"linux1" {69b544d2-bf64-4f83-a525-a7f2dd2007e7}


Now  lets create a shared asm drive for ASM :

Note : Always pick a different location, but make sure they are outside the existing VM directory.

$ mkdir C:/VirtualBox/
$ cd C:/VirtualBox/
$
$ # Create the disks and associate them with VirtualBox as virtual media.

VBoxManage createhd --filename asm1.vdi --size 5120 --format VDI --variant Fixed

C:\Virtualdisks>VBoxManage createhd --filename asm1.vdi --size 5120 --format VDI
 --variant Fixed
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
Disk image created. UUID: c8a5ef46-7304-4ea0-b685-e1efbf6ab41e

$ # Connect them to the VM.

VBoxManage storageattach linux1 --storagectl "SATA" --port 1 --device 0 --type hdd --medium asm1.vdi --mtype shareable


$ # Make shareable.

$ VBoxManage modifyhd asm1.vdi --type shareable

We now have shared disks added to Virtual box.

We can also add these shared disks via Graphical interface :

See below for instructions:


Step 1 :

Select >> add hard disks >>

Step 2:


select vdi

Step 3


select fixed size

Step 4

it will be added now.

Step 5


select (virtual box top left) File >> virtual Media manager >> select disk you want to modify >> right click >> click modify

Step 6


Select modify and close.

Note : 

If you are going to use this for RAC setup. make sure you attach this shared disks to both of your environments.
