I have got a PowerCli script for this 
- we are facing the same bug on HP blades in our environment
What it does is basically everything described above, but without tne hassle of connecting to each host manually - it's a little bit modular so take a look on the code first if you understand the mnemonics, if not just run it, enter your vCenter and VM name (don't forget to see the $hosts value - it should contain your domain't name!) and wait for a moment
