VCSA to update the single host the VCSA appliance resides on?

VCSA 6.7 Update Manager

If I have a small environment with one host, local storage and want to use VCSA on that host to update the host/vmware tools for any of the guests etc, am I able to do it from VCSA running from that single host?

Thanks!!!

Guests are fine but host may be an issue depending if the host needs to be placed in maintenance mode.  This would need to be completed via CLI.

You cannot update the host, because the host needs to be in maintenance mode and ALL VMs off, including VCSA, if VCSA is OFF, you cannot run Update Manager.

Therefore updates need to be done manually in maintenance mode, which is very easy.

Type the following via SSH or shell prompt on the ESXi host (in maintenance mode all VMs off!)

esxcli network firewall ruleset set -e true -r httpClient
esxcli software profile update -p ESXi-6.7.0-20190504001-standard -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml
esxcli network firewall ruleset s

Open in new window

et -e false -r httpClient

Assuming Host has access to Internet.

Hey Andrew

I was thinking the same thing actually that I could not, but what if.... What if, or rather can I run the vcsa, or the update manager on a VM running on an admin desktop that is running VMWare workstation, could that work for a single host environment, or simply not worth the trouble?

Thanks Andrew!

If VCSA is not running on the host to be updated. BUT it still has to put the host into maintenance mode, and therefore ALL VMs on that Host also need to be powered off.

So are you going to move all those VMs to VMware Workstation as well ?

To be honest with you, CONVERTING to workstation (which is required) using VMware Converter, it's not worth the effort.

Update only takes 5 minutes!

Hey Andrew

Allow me to clarify, and again it may or may not make sense to run VSCA from VMware WS.  My question was if you can just run VCSA from workstation, (I think it would have to be relatively robust though), and I am aware of having to bring down the guests on the host before putting the host into maintenance mode.  But not sure if it is something you could do, or even if it is worth doing. Or simply update the host via SSH, which please correct me if I am wrong, should also update the tools so with the host being current, I then should be able to update the VMWare tools on each guest.  Once the host is updated, exit maintenance mode and bring up the VMs from the VCSA running on workstation.  Again, just a thought, not sure if can/or worth doing however.

Thanks

Yes, but it needs to be converted using VMware Converter.

Yes Correct.

I then should be able to update the VMWare tools on each guest.  Once the host is updated, exit maintenance mode and bring up the VMs from the VCSA running on workstation.  Again, just a thought, not sure if can/or worth doing however.

Yes, Correct.

But a lot of effort for nothing here!

That is what I was trying to find out, if it is worth it for the smaller environments with a single host, or if there was a better way to do it, such as running VCSA in workstation.  I appreciate you entertaining my question and your suggestion!

And that is what I was trying to find out!  Not worth it.  What's the worst case the updates blow up the host and you reinstall? Have you ever really seen that happen?  I think it generally goes pretty well!

Thanks for your time and suggestions

You can always rollback the upgrade!

Yes, but I've done a very unusual amount of upgrades in 20 years!
