vSphere HA and vApps
Published on 12 Nov 2011 · Filed in Explanation · 114 words (estimated 1 minutes to read)This is probably obvious to most everyone, but for those who don’t already know it’s important to point this out: vSphere HA does not honor vApp startup settings. So while you can go into the properties for a vApp and define the order in which VMs will start (or stop) and the timing between those actions, vSphere HA will not recognize or honor those settings. Therefore, in a situation where an ESX/ESXi host fails and that host is running a vApp, the individual VMs in the vApp could be restarted in an entirely different order than what you specified in the vApp settings.
Be sure to plan accordingly when using vApps in your environment.
