esxi5 manual update

[aiea96701]

We have vCenter5 and 3esxi5 hosts o

In a drs/ha cluster.  We don't have update manager functioning but need to perform esxi patching.

I know I could do it individually for each host using command line.  Since vCenter is operational I wonder if there is a way to script patching of all the hosts in the cluster.  Is there an example script I could use to do this?

I know this sounds odd and that using VUM would be the better option but there is a good reason for this

Thanks in advance

Take a look at this blog post: Quickest Way to Patch an ESX/ESXi Using the Command-line | VMware vSphere Blog - VMware Blogs

And instead of use a script to automate the whole cluster upgrade, I suggest you do the upgrade of the host one by one, and follow to the next only after confirm everything is ok.

many thanks.   That's what I have been doing to our standalone hosts.  Thought I'd give it a shot to see if there was a script that could do it automatically vs VUM.   I presume that since vCenter is still functioning fine that I could put each host in Maintenance Mode and allow vMotion to migrate the VMs to other hosts and then via SSH manually update.   But, that would have been still one at a time.

Thanks much
