A hosed up deployment?
I made several google search before posting but I did not find anything related to esxi with empty /proc folder , it might be my mistake
I did not made the deployment of the server which looks like running fine, however we'd to look at /proc/scsi folder which is actually missing
Probably I did not add many information but at the moment I have not much more than that
Other than you looking in /proc and finding it empty, is there a problem with this host? Is it exhibiting any problematic symptoms? Or are you just "curious" at this point?
Maybe you are not using the root account ?
