2 Recompose the desktop pool again.
View Composer creates a base image from the snapshot and recreates the linked-clone OS disks.
View Composer persistent disks that contain user data and settings are preserved during the
recomposition.
Depending on the conditions of the incorrect recomposition, you might refresh or rebalance the linked
clones instead of or in addition to recomposing them.
NOTE If you do not configure View Composer persistent disks, all recompositions delete user-
generated changes in the linked-clone virtual machines.
Rebalance Linked-Clone Virtual Machines
A rebalance operation evenly redistributes linked-clone virtual machines among available datastores.
You can also use the rebalance operation to migrate linked-clone virtual machines to another datastore. Do
not use vSphere Client or vCenter Server to migrate or manage linked-clone virtual machines. See “Migrate
Linked-Clone Virtual Machines to Another Datastore,” on page 159.
If possible, schedule rebalance operations during off-peak hours.
For guidelines, see “Rebalancing Linked Clones Among Logical Drives,” on page 158.
Prerequisites
n
Familiarize yourself with the rebalance operation. See “Rebalancing Linked Clones Among Logical
Drives,” on page 158.
n
Decide when to schedule the rebalance operation. By default, View Composer starts the operation
immediately.
You can schedule only one rebalance operation at a time for a given set of linked clones. You can
schedule multiple rebalance operations if they affect different linked clones.
n
Decide whether to force all users to log off as soon as the operation begins or wait for each user to log
off before rebalancing that user's linked-clone desktop.
If you force users to log off, View notifies users before they are disconnected and allows them to close
their applications and log off.
If you force users to log off, the maximum number of concurrent rebalance operations on remote
desktops that require logoffs is half the value of the Max concurrent View Composer maintenance
operations setting. For example, if this setting is configured as 24 and you force users to log off, the
maximum number of concurrent rebalance operations on remote desktops that require logoffs is 12.
n
Verify that provisioning for the desktop pool is enabled. When pool provisioning is disabled, View
stops the virtual machines from being customized after they are rebalanced.
n
If your deployment includes replicated View Connection Server instances, verify that all instances are
the same version.
