• The typical way to apply patches to ESXi hosts is through the vCenter Update Manager. See the vCenter Update Manager Administration Guide.
• You can also update ESXi hosts by downloading the most recent O (offline) patch bundle from http://support.vmware.com/selfsupport/download/ and installing the bundle using VMware Infrastructure Update or by using the vihostupdate command through the Remote Command-Line Interface (RCLI).
