CLI commands to install patch bundle ZIPs?

This has changed a lot since 4.1, and I'm not grokking the syntax for CLI upgrades.

vCenter upgrade manager isn't an option at the moment, so I need to do it via CLI but the VMware documentation examples aren't really very clear.

Hi, does the new patch include all previous [two] patches or do I need to install each one?  Thanks

Patches are cummulative.  Each patch is essentially a complete version of ESXi.

When you install ESXi there are two hypervisor partitions.  With a fresh install only the first contains an ESXi image and the 2nd is emtpy.  The first is /bootbank when you access the shell and the 2nd is /altbootbank.

When you patch your host the new image is written to /altbootbank (/bootbank is left untouched).  When ESXi next boots,  the two bootbanks are switched so the newest becomes /bootbank.  The process repeats when you next patch your host.  Once advantage to this method is that you can quickly revert to the prior version if you have a problem after updating.  Shift+R during the initial boot screen gives you the option to revert back to the old version.
