How to Deploy Bulletins to Your Managed Hypervisors
The Bulletins tab can be used to deploy missing bulletins to your managed ESXi hypervisors. You simply select the desired bulletin(s) and then click Deploy selected bulletins. Note that because you can only deploy bulletins to one hypervisor at a time, if you select bulletins from two or more hypervisors, the Deploy selected bulletins button will no longer be available. For more information on the bulletin deployment process, see Configuring an ESXi Deployment.
TIP: Use the Only show latest check box to view only those bulletins that are not replaced by newer bulletins.
