title: How to Roll Back ESXi Patch/Upgrades?
body: <p>Using vSphere Update Manager I've installed some updates and patches onto my host, however I have an issue with it picking up a datastore now so I want to roll back these changes to see if that fixes the issue.</p>
  
  <p>From my research I understand that you can't uninstall these patches and you have to revert back to a previous ESXi version. I'm attempting to do this following the steps here: <a href="https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&amp;cmd=displayKC&amp;externalId=1033604" rel="nofollow noreferrer">https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&amp;cmd=displayKC&amp;externalId=1033604</a></p>
  
  <p>However it does not give reference on how to access the Console for the Host. I can't find a way to access it in vSphere, but found a way by downloading putty and running the DCUI command.</p>
  
  <p><strong>The problem I have is that it says Reboot and then:</strong></p>
  
  <p><strong>When the Hypervisor progress bar starts loading, press Shift+R.</strong></p>
  
  <p><strong>However when I reboot putty loses connection to the host (presumably because it is rebooting) so I never get to see the boot up screen and Hypervisor progress bar to press Shift+R.</strong></p>
  
  <p>Am I missing something simple here? Server is Dell running ESXi 5.5. Thank you.</p>
