I have two VMware hosts with vCenterServer running in a vm on one of the hosts. Update Manager is loaded and works fine.
I would like to update (install patches) the host that has VCenterServer on it. Tech support said that they could not tell me that it was OK to do a staged update with UpdateManager on the host. My plan was to push the updates out, then use vSphere client to manually reboot the host that is home to the VCenterServer. It makes sense that this would work, but the tech told me to create a second vCenterServer on the other host. That is a lot of work.
Has anyone successfully done what I was planning to do? Watching UpdateManager patch the first host, it appears that Update Manager pushes the updates to the host, then goes into maintenance mode, and reboots. Why not push the updates, then manually reboot?
Any other suggestions or ways to do this from the console?
