ESXi 6 host patches update without interrupting guests?

[sukiVM]

Hi All,

Is there a way to update ESXi 6 host patches when guest vms are running and without interrupting them?

I dont Vmotion at this moment.

Thank you.

You may need to restart the host after the Patch Deployment. So definitely you have to move or shutdown Guests.

Thank you very much for the quick clarification

Hi,

Normally, I vMotion VMs off one Esxi host, upgrade through command line (Putty) and then reboot the host.

Even though there would and should be no impact to running VMs, I would say to vMotion VMs, update ESXi host and reboot it during same maintenance window when you have it.

Don't keep the hosts not-rebooted, after update, running for long.

Let me know why you want to update ESXi hosts with VMs running on them / without rebooting hosts.

Edit: formatting.

Hi Suki,

you can look up the release notes of the patches or in the Update Manager. It is documented if the patches need a reboot or not. Most core-patches do need reboots though.

Hiii,

Thank you for the reply. I have few critical applications running in Guests. This is the reason I am exploring options to patch the system without rebooting.

I do not  have vmotion at this moment.

Warm regards,
