With the Enable stateful installs on the host host profile, Auto Deploy installs the image. When you
reboot the host, the host boots from disk, just like a host that was provisioned with the installer. Auto
Deploy no longer provisions the host.
You can apply the host profile from a vSphere Web Client, or write an Auto Deploy PowerCLI rule that
applies the host profile.
Each workflow supports stateless caching and stateful installs.

8. Workflows that set up hosts for stateless caching or stateful installs
Workflow Stateless caching Stateful install
Apply host profile from
vSphere Web Client
Apply the host profile either to
individual hosts or to all hosts in a folder
or cluster. No reboot required.
Apply the host profile either to individual
hosts or to all hosts in a folder or cluster.
Reboot is required.
Write and apply PowerCLI
rule
Set up a reference host with a host
profile that has the caching setup you
want. Write a PowerCLI rule that
provisions the host by using Auto
Deploy and that applies a host profile
that is set up for stateless caching.
Reboot is required.
Set up a reference host with a host profile that

PowerCLI rule that provisions the host by
using Auto Deploy and applies a host profile
that is set up for stateful installs. Reboot is
required.
Applying the System Cache Configuration Host Profile from the vSphere Web Client
You can create a host profile on a reference host and apply that host profile to additional hosts or to a
vCenter Server folder or cluster. The following workflow results.
1
You provision a host with Auto Deploy and edit that host's System Image Cache Configuration host
profile.
2 You place one or more target hosts in maintenance mode, apply the host profile to each host, and
instruct the host to exit maintenance mode.
3 What happens next depends on the host profile you selected.
n
If the host profile enabled stateless caching, the image is cached to disk. No reboot is required.
n
If the host profile enabled stateful installs, the image is installed. When you reboot, the host uses
the installed image.
4 A reboot is required so the changes can take effect.
Applying the System Cache Configuration with PowerCLI
You can create a host profile for a reference host and write an Auto Deploy PowerCLI rule that applies that
host profile to other target hosts. The following workflow results.
1
You provision a reference with Auto Deploy and create a host profile to enable a form of caching.
2 You write a rule that provisions additional hosts with Auto Deploy and that applies the host profile of
the reference host to those hosts.
