I am dealing with a virtual machine that is receiving the following entry in the event log:

> 
> TIME OF EVENT: 7/30/2011 3:47:05 PM  
>  EVENT LOG: System  
>  EVENT
>  SOURCE: disk  
>  EVENT ID: 7  
>  SEVERITY: Error  
>  DESCRIPTION: The

Pretty standard fare if this was a physical server, but I need to determine if this is an issue with a .vmdk file have a 'virtual' bad block or if this is occurring because of a physical disk on the SAN.

Is there a way to determine this *without* taking the VM offline?
