Jsut a quick one. I am going to upgrade my 2 physical ESXi 5.0 servers to 5.1. I have vSphere 5 isntalled onto a VM (I run the Essentials Plus kit) from which I have been administering the vmware environment successfully. My ESXi 5.0 hosts are all patched and up to date and I am comfortable with using the update manager to stage and remidiate those host patches.....but I'm not 100% sure on the process of upgrading to 5.1 :)
After some reading I am assuming that I need to download the full 5.1 ESXi install and 'upgrade' my hosts by attaching that image file into Upgrade Manager - correct? I think thats how I've read it, but confirmation would be nice....as would a few pointers ;)
Also, my physical hosts are Dell R710's....when I installed ESXi 5.0 onto them I just used the standard ESXi 5.0 installer from vmWare - is ther ea 5.1 iso image from Dell for the R710 and should I be using that over the vmware 5.1 package??
Any tips and advice is, as per usual, greatly appreciated ;)
Cheers :)
I could not find a Dell image for 5.1 - we just used the offical VMware images.
Basically what you've outlined is correct (I'm re-writing this from memory, so let me know if the steps are a tad off):
One thing that I wish I had found out before the vSphere 5.1 upgrade is that VMWare Converter cannot connect to 5.1 instances, and VMWare show absolutally no interest in fixing this bug - you can either use an older version of VMWare Converter (if you're trying to migrate from Hyper-V to ESXi like we are, then the older versions won't connect to the latest Hyper-V) or you can wait it out, or do a local P2V and then upload the image via the datastore manager.?Turns out there is a VMWare Converter 5.1 beta released a week ago.
In addition to the answer Mark provided, you'll want to upgrade your vCenter Server before you upgrade your hosts. Here's a document that provides details on the upgrade process:
