VUM PowerCLI
cmdlets available
To use the VUM PowerCLI, you need to i rst install the vSphere PowerCLI and then down-
load and install the Update Manager PowerCLI package. You can get more information about
this package from VMware's own “VMware vSphere Update Manager PowerCLI Installation
and Administration Guide” for VUM 5.5.
Upgrading and Patching without vSphere Update Manager
You can maintain your vSphere environment, keeping the elements patched and upgraded,
without resorting to the use of VUM. Also, you may want to use VUM for certain updating
tasks but take an alternative approach for others. For example, you might not want to use VUM
in the following situations:
You are using the free stand-alone vSphere ESXi hypervisor, which does not come with
vCenter Server. Without a licensed vCenter Server, you can't use VUM.
◆
You have only a small environment with one or two small host servers. To maximize
the use of your server hardware for VMs, you don't want the infrastructure overhead of
another application and another database running.
