Overview of Working with Systems | |
Systems can represent physical hardware, Virtual Machines
(VM), or Virtual Machine Hosts. They can be real systems from your
current environment or “What-If” creations to represent new
systems you are planning. You can also modify a system based on an
existing system to represent planned configuration changes. The following
tasks are described:
Creating a System | |
When developing a scenario to model future configurations, you can
create systems to represent systems you are considering adding to the
configuration. | | | |  | IMPORTANT: You must decide during the initial creation the name and if the
system is going to be a Virtual
Machine (VM) or a host for virtual
machines (VM Host). You cannot change these once
the system has been created. | | | | |
Prerequisites. To create a system in a scenario:
Procedure 4-21 To Create a System in a Scenario If you are not on the System tab, click
the System tab. The System tab will open, listing the systems
in the scenario. Select What-If Action Create System... from the menu-bar. The Edit Scenario - Create System screen will
be displayed. Fill in the System Name field. This name must
not be the same as any other system name in the VSE environment. The
only characters allowed are upper and lower case alpha, numeric, and
the dash and period. The first character must be an alpha character.
You cannot change the name once the system is created. Select the appropriate System Type. If there
are no VM Hosts, the VM choice will be disabled. | | | | | IMPORTANT: You cannot change this once the system has been created. | | | | |
If you have selected VM in the previous step, select a VM
Host. Modify the CPU Resources as
appropriate. Modify the Memory as appropriate. If you have other systems to create, click the
Apply button and repeat the preceding 5 steps,
otherwise, proceed to the following
step. Click the OK button. The System tab of the Capacity
Advisor - Edit Scenario screen will open.
What Now? Once you have created a system, you might want to:
Adding an Existing System | |
As your environment changes, you may want to add an existing system to
a scenario. Prerequisites. To add existing systems to a scenario:
Procedure 4-22 To Add an Existing System to a Scenario If you are not on the System tab, click
the System tab. The System tab will open, listing the systems
in the scenario. Select EditAdd Existing Systems... from the menu-bar. The Edit Scenario - Add Existing Systems
screen will be displayed. The systems with available
HP Integrity Essentials Capacity Advisor data will be displayed in a list with check
boxes beside them. Any systems licensed for Capacity Advisor will be
named below the list. If any of the systems you want to add to the scenario are not
displayed on this page, you need to license them for Capacity Advisor
(see the section “Activating
Licenses” in
VSE Management Software Quick Start Guide —
Part Number T2786-90012) and collect
data on them (see Collecting Data). If the systems you wish to add to the scenario are in the list of
licensed systems without available Capacity Advisor data, collect data
on them (see Collecting Data)
and continue with the next step. Click in the check boxes beside the systems you want to add to the
scenario to select them. Check marks will appear in the check boxes and the row containing
he system will highlight to indicate selection. Click the OK button. The System tab of the Capacity
Advisor - Edit Scenario screen will open.
What Now? Once you have added a system to a scenario, you might want to:
Editing a System | |
When constructing a scenario, it is frequently necessary to modify the
characteristics of a system to reflect future changes to existing hardware
or to reflect the characteristics of a planned system. Prerequisites. To edit a system in a scenario:
Procedure 4-23 To Edit a System If you are not on the System tab, click
the System tab. The System tab will open, listing the systems
in the scenario. Click the check box preceding the name of the system you wish
to edit. A check mark will appear in the check box. Select What-If ActionEdit System... from the menu-bar. The Edit Scenario - Edit System screen will
be displayed in a new window. Modify the CPU Resources and/or
Memory parameters as desired (click the
? button to access help for details on the
controls). | | | | | IMPORTANT: You cannot modify the CPU speed of a virtual machine (VM); you
must modify the CPU speed of a VM Host, which will modify the speed
of all VMs hosted by it. | | | | |
Click the OK button. The System tab of the Capacity
Advisor - Edit Scenario screen will open.
What Now? Once you have edited a system, you might want to:
Moving a Virtual Machine | |
Moving Virtual
Machines (VMs) among VM Hosts allows you to redistribute
virtual equivalents of existing systems across physical servers. Prerequisites. To move a virtual machine:
Procedure 4-24 To Move a Virtual System If you are not on the System tab, click
the System tab. The System tab will open, listing the systems
in the scenario. Click in the check box preceding the virtual system you wish to
move. A check mark will appear in the check box. Select What-if ActionMove Virtual Machine... from the menu-bar. The Edit Scenario - Move Virtual Machine
screen will be displayed, with a list of all the VM Hosts available to
host the VM. | | | |  | NOTE: Bar-graphs representing the CPU Utilization
and Memory Utilization that will exist if the
VM were moved to each of the VM Hosts provide a quick estimate of
how the VM will “fit” on each of the host
systems. | | | | |
Click in the circle preceding the name of the VM host that will be
the new host for the VM. The circle will be filled in and the row containing the VM Host
will be highlighted indicating the selection. Click the OK button. The System tab of the Capacity
Advisor - Edit Scenario screen will open.
What Now? Once you have moved a virtual machine, you might want to:
Removing a System | |
As your scenarios evolve, you might need to remove systems from a
scenario to represent planned or actual changes. Prerequisites. To remove systems from a scenario:
Procedure 4-25 To Remove Systems from a Scenario If you are not on the System tab, click
the System tab. The System tab will open, with a listing the
systems in the scenario. Click in the check boxes beside the systems you want to remove
from the scenario to select them. Check marks will appear in the check boxes. Select EditRemove Systems... from the menu-bar. A confirmation screen listing the systems you are removing will be
presented. Click the OK button. You will be returned to the Capacity Advisor - Edit
Scenario screen with the systems you selected
removed.
What Now? Once you have removed systems, you might want to:
