Rebalance Linked-Clone Desktops - VMware View Manager 4.5 Admin Manual

VMware View Administrator's Guide
Depending on the conditions of the incorrect recomposition, you might refresh or rebalance the linked
clones instead of or in addition to recomposing them.
N If you do not configure View Composer persistent disks, all recompositions delete user-generated
OTE
changes in the linked-clone desktops.
Prepare an ESX Host or Cluster to Support Parent Virtual Machine Hardware v7
To recompose linked-clone desktops with a parent virtual machine that you upgraded to hardware v7, you
must deploy the linked-clone pool on an ESX/ESXi host or cluster that is version 4.0 or later, and the pool must
use vSphere mode.
When you recompose a linked-clone pool that is not using vSphere mode, you cannot use a snapshot of a parent
virtual machine that is upgraded to hardware v7. The snapshot does not appear in the recompose wizard.
Before you recompose the linked clones, take the steps described in this procedure.
Prerequisites
Verify that the parent virtual machine that you intend to use to recompose the linked clones was upgraded
n
to hardware v7. A virtual machine with hardware v7 must run on an ESX/ESXi host that is version 4.0 or
later. For information about upgrading View components, see the VMware View Upgrade Guide.
Prepare the parent virtual machine for the recompose operation. For details, see
n
Machine to Recompose Linked-Clone Desktops,"
Procedure
1 In vCenter Server, in the cluster on which the pool is deployed, upgrade all ESX hosts to version 4.0 or
later.
Alternatively, you can use another cluster in which all ESX hosts are version 4.0 or later.
2 In View Administrator, click Inventory > Pools.
3 Select the pool to recompose.
4 Click Desktop (View Composer).
5 Select the Settings tab and click Edit.
6 Select the vCenter Settings tab.
7 Next to Host or Cluster, click Select.
If the parent virtual machine is hardware v7, only ESX hosts or clusters at version 4.0 or later are displayed.
8 Select a host or cluster.
9 Check Use vSphere mode for View Composer and click OK.
What to do next
Recompose the linked-clone desktop pool.

Rebalance Linked-Clone Desktops

A desktop rebalance operation evenly redistributes linked-clone desktops among available datastores.
If possible, schedule rebalance operations during off-peak hours.
