Prerequisites
If you upgrade the parent virtual machine hardware to v7, deploy the linked clone pool on an ESX/ESXi 4.0
host
or cluster. You cannot deploy the pool on a cluster with ESX/ESXi 4.0 hosts mixed with ESX/ESXi 3.5 hosts.
Procedure
1 In vCenter Server, update the parent virtual machine for the recomposition.
n
Install OS patches or service packs, new applications, application updates, or make other changes in
the parent virtual machine.
n
Alternatively, prepare another virtual machine to be selected as the new parent during the
recomposition.
2 In vCenter Server, power off the updated or new parent virtual machine.
3 In vCenter Server, take a snapshot of the parent virtual machine.
4 If the parent virtual machine hardware is v7, make sure that the linked-clone pool uses vSphere mode.
a In View Administrator, click Inventory > Pools.
b Select the pool to recompose.
c Click Desktop (View Composer).
d Select the Settings tab and scroll to display the vCenter Server panel.
e Check that Using vSphere mode is set to Yes.
If this setting is No, the cluster on which the pool is deployed includes one or more ESX 3.5 hosts. To
deploy a linked-clone pool from a base image with hardware v7, you must upgrade all ESX hosts in the
cluster to version 4.0 or select a another cluster with all ESX 4.0 hosts. You also must configure the pool
to use vSphere mode. For details, see “Prepare an ESX Host or Cluster to Support Parent Virtual Machine
Hardware v7,” on page 168.
What to do next
Recompose the linked-clone desktop pool.
Recompose Linked-Clone Desktops
Desktop recomposition simultaneously updates all the linked-clone desktops anchored to a parent virtual
machine.
If possible, schedule recompositions during off-peak hours.
Prerequisites
n
Verify that you have a snapshot of the parent virtual machine. See “Prepare a Parent Virtual Machine to
Recompose Linked-Clone Desktops,” on page 163.
n
Familiarize yourself with the recomposition guidelines. See “Updating Linked Clones with Desktop
Recomposition,” on page 166.
n
Decide when to schedule the recomposition. By default, View Composer starts the recomposition
immediately.
You can schedule only one recomposition at a time for a given set of linked clones. You can schedule
multiple recompositions if they affect different linked clones.
