Windows VM with Multiple vmdks.

We have a windows vm with multiple disks (vmdk).  Noticed that each vmdk are named as _1.vmdk,_2.vmdk etc in the datastore. We have about eight disks.
One day we may have to increase the size of a disk, but we do not know which vmdk disk corresponding to windows disk/drive.
How do we identify the vmdk belongs to windows drive?

If you are using VMware Workstation, when you set up a new machine, the default is multiple disks and you should be able to add another disk.

I use one disk and make it big enough (but not pre-allocated) for any future needs.

This is not easy, and does require you to complete some documentation, to ensure the OS relationship is correct e.g.

C: ---> _1.vmdk
E: ---> _3.vmdk

You can use RV tools from here which can assist http://www.robware.net/

The easiest method is to make sure that you do NOT make them all the same size!

Vary the sizes by a few GB!

With the scsitargetid from Windows side and Disk ID you can identify from both sides.

Here is a great post from  Nick Colyer that I use when I need to identify both, and I had always the right Disks.


Hope this can help.
