I'm in a bit of confusion about how to proceed with my VSphere Essentials 6 install. I've installed the server software, but I have a few problems.
First of all, the environment: Two ESXi 5.5 hosts that have been running for some time, using the free version of the hypervisor without any VCenter Server software, and have been managed using the VSphere client. We just purchased a license for VSphere Essentials 6 and I've installed it on one of our virtual hosts. I can open the management tools, either VSphere client or the web console on the server with no problem.
So, my problems:
1. I cannot open the web client successfully on my Windows 7 workstation in IE11. It keeps asking me to install the client plugin, but when I try to install it again, the client plugin says it's already installed. It doesn't show on the list of add-ins in IE. OK, I get it, no one like IE. However, I was able to install the plugin in Firefox, but I get a warning message every time I open it that the version of Firefox (26) that I'm running is too old and I must upgrade to 30. Anyway, it seems to open, but I don't know if I'm missing some essential ("Essentials") functions.
2. The big problem is with my host licenses. I understand that since these were originally installed using the free hypervisor that I have to somehow license these hosts for the VSphere client agent. When I try to add a host I get this message: "The VMware vSphere 5 Hypervisor license for Host server.domain.org does not include vCenter agent for VMware host. Upgrade the license."
I didn't have this problem the last time I did a similar upgrade, but that was to VSphere Enterprise and it was version 5.5. Regardless of how much searching I do, I can't find the (what I would think would be very simple) instructions on HOW to upgrade the license. These hosts were just upgraded to 5.5U2. Do I have to upgrade them to 6.0? How do I do that if I can't add them to the datacenter I've created in VSphere Essentials? Also, these servers are Proliant ML350 G6's and I don't think they're officially on the list as compatible with ESXi 6.
Any suggestions or instructions would be appreciated.
