Procedure
1 Choose whether to rebalance the whole pool or a single virtual machine.
Option Action
To rebalance all virtual machines in
the pool
a In View Administrator, select Catalog > Desktop Pools.
b Select the pool to rebalance by double-clicking the pool ID in the left
column.
c On the Inventory tab, click Machines.
d Use the Ctrl or Shift keys to select multiple all the machine IDs in the
left column.
e Select Rebalance from the View Composer drop-down menu.
To rebalance a single virtual
machine
a In View Administrator, select Resources > Machines.
b Select the machine to rebalance by double-clicking the machine ID in
the left column.
c On the Summary tab, select Rebalance from the View Composer drop-
down menu.
2 Follow the wizard instructions.
The linked-clone virtual machines are refreshed and rebalanced. The OS disks are reduced to their original
size.
In View Administrator, you can monitor the operation by selecting Catalog > Desktop Pools, double-
clicking the pool ID, and clicking the Tasks tab. You can click Cancel task, Pause task, or Resume task to
terminate a task, suspend a task, or resume a suspended task.
Rebalancing Linked Clones Among Logical Drives
A rebalance operation evenly redistributes linked-clone virtual machines among available logical drives. It
saves storage space on overloaded drives and ensures that no drives are underused.
When you create large linked-clone desktop pools and use multiple Logical Unit Numbers (LUNs), the
space might not be used efficiently if the initial sizing was inaccurate. If you set an aggressive storage
overcommit level, the linked clones can grow quickly and consume all the free space on the datastore.
When the virtual machines use 95% of the space on the datastore, View generates a warning log entry.
The rebalance also refreshes the linked clones, reducing the size of their OS disks. It does not affect View
Composer persistent disks.
Apply these guidelines to rebalances:
n
You can rebalance dedicated-assignment and floating-assignment desktop pools.
n
You can rebalance selected linked clones or all clones in a pool.
n
You can rebalance a desktop pool on demand or as a scheduled event.
You can schedule only one rebalance operation at a time for a given set of linked clones. If you start a
rebalance operation immediately, the operation overwrites any previously scheduled task.
You can schedule multiple rebalance operations if they affect different linked clones.
Before you schedule a new rebalance operation, you must cancel any previously scheduled task.
n
You can only rebalance virtual machines in the Available, Error, or Customizing state with no
schedules or pending cancellations.
n
As a best practice, do not mix linked-clone virtual machines with other types of virtual machines on the
same datastore. This way View Composer can rebalance all the virtual machines on the datastore.
