Keeping VMware ESXi Updated: 6.5 Update 1

So you might have followed my post about upgrading to VMware 6.5 from 5.5U3 using the console. It’s been a while since then, and those folks over at VMware have updated the platform a little.

It’s now at ESXi 6.5 Update 1, and you want to get your system up to date. So let’s get to it.

Note: Since 6.5.0, VMware have changed the format of their profile bundle name, it now uses a date based format and not a build number.

esxcli network firewall ruleset set -e true -r httpClient
esxcli software profile update -p ESXi-6.5.0-20170701001s-standard -d
esxcli software profile update -p ESXi-6.5.0-20170702001-standard -d
esxcli network firewall ruleset set -e false -r httpClient

The first line allows the internal HTTP Client to reach the outside world through the firewall. The second line downloads a patch for the tools-light .VIB (and maybe a few others). Then the updates for the latest ESXi are downloaded and then applied. The last line closes the internal client to the network.

You can monitor the update process through the Web Console by selecting the/var/log/esxupdate.log file in the Log Viewer, (Host|Monitor|Logs).

Don’t forget to reboot
