将VM Drive映射到相应的VMDK文件

Question

• Problem:

  Lets say i have a VM with three storage LUNS attached to it through SCSI VMFS stores each drive as a individual VMDK files.

  1. C:(one_c.vmdk)
  2. D:(two_d.vmdk)
  3. F:(three_f.vmdk)

In ESX host these there vmdk files are stored in /container_name/vm_name/

Is there any way of mapping,given (disk serial number or disk id) and vmdk files location can we figure out to which vmdk file this Drive maps to?

Note: i have gone through this link VMWare VMDK mapping to Windows Drive Letters . But not that keen to do using scripts

Answer 1

You can use ReconfigVM_Task for the virtual machine that has those disks attached. You need to pass virtualMachineConfigSpec which, as the name implies, specifies the virtual machine's configuration. Under it you will find virtualDeviceConfigSpec

What you want to do is:

• Fetch the existing virtualMachineConfigSpec of your VM
• Locate the relevant virtualDeviceConfigSpec for your disk
• Edit the backing info of that disk
  • Change the file name to the correct path (starting from the datastore)
  • Unset the fileOperation (to avoid creating a new disk there)
• Execute ReconfigVM_Task on the VM with the updated spec

Please consult the doc for more specific instructions
