Removing a VMware DRS cluster from a scenario
1. Select What-If Action→Undo/Edit/View Applied What-If Actions .
2. Disable or Delete the row(s) containing the record of creating the cluster and any rows that
record making the VM host(s) and the VM guests members of the cluster. (See
“Undo/edit/review applied what-if actions in a scenario” (page 69) for more information on
using this screen.)
3. Close the Undo/Edit/View Applied What-If Actions window to return to the updated System
tab.
Moving a virtual machine
Moving Virtual Machines (VMs) among VM hosts allows you to redistribute virtual equivalents of
existing systems across physical servers. Capacity Advisor automatically takes into account use of
dynamic memory by a virtual machine.
NOTE: Performance for a virtual machine is usually calculated using the performance index
calculated for its VM host. However, when a virtual machine is moved from one VM host to another
having a different clock speed, performance is calculated using a combination of clock speed and
the performance index of the destination host. To get the best possible measure, collect the desired
amount of data from a VM before moving it to host of a differing CPU clock speed.
1. From the System tab in the scenario editor, click the check box preceding the virtual system(s)
that you want to move. You must include at least two VM hosts. One from which you will be
moving the VMs, and one to which you will be moving the VMs.
2. Select What-if Action→Move Virtual Machines... from the menu bar.
The Edit Scenario: Move Virtual Machines screen displays.
3. Change the Meter Style, if desired.
4. Change the Data Range if a different size of data collection is desired, and click OK to refresh
the table display.
TIP: A longer data collection period provides a better picture of activity on the system over
time than shorter periods do.
5. Change the Meters Represent setting if a different calculation is desired .
6. The first table presents the virtual machines selected for the move.
7. Optional. Change the headroom calculation. You must click Refresh to update the server
destination table with the new values.
8. Within the table titled To: (Selected VM Host), select a destination VM host for the previously
selected systems. The OK button becomes enabled for use.
Server presentation:
The table entries are ordered by headroom fitness as determined by Capacity Advisor, and
Capacity Advisor selects the top selection by default. Examine the headroom rating and the
utilization meters for each prospective host to determine which host best fits your goals for
headroom fitness and optimal utilization.
