ESXi host hangs on “usbarbitrator starting”

While upgrading our ESXi 4.1 hosts to ESXi 5.5 I found that the host would hang for almost a half hour on “usbarbitrator starting”. I did a little research and found this article It said that you should disable the usbarbitrator service.

Start the ESX host and enter the following command at the Linux service console command line:
chkconfig usbarbitrator off

After I did that and rebooted the host, it was a much faster boot time and I was much happier.

Install of vCenter 5.5 hangs on Server 2012 R2

When I was installing vCenter 5.5 on a Server 2012 R2 vm in my home lab I had a problem with it hanging on “Installing Directory Services”. After trying to uninstall and reinstall a few times I discovered that Server 2012R2 does not include the OCSetup.exe file in %WinDir%\System32\ folder. I went to an existing instalation of Server 2008R2 and copied the file to my Server 2012R2 installation and reinstalled vCenter with no problem.
