As I´ve posted about earlier, you can update your ESXi hosts to a new release from the command line. Now that ESXi 5.5 has been released, the same procedure can be applied to upgrade once more.
Place the host in maintenance mode, then run the following command to do an online update to ESXi 5.5:
~ # esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-5.5.0-1331820-standard
While this runs, monitor the log file to check upgrade process:
~ # tail -f /var/log/esxupdate.log
Let it run for a while all the way until it´s finished, reboot the host and hey presto, fresh new ESXi 5.5 upgrade completed! Quick and dirty, just the way we like it.
To verify the version, still using the command line, issue the following command:
~ # vmware -l VMware ESXi 5.5.0 GA
Update 16.02.2015 #
To find out which patches to apply, and what the correct profile name would be, check out the VMware ESXi Patch Tracker by Andreas Peetz. It’s a great resource to keep track of patches for your ESXi hosts.
