Using the VMware Modify
Virtual Machine Task, you
can modify the disk size, memory size, and number of processors of
existing virtual machines from the IBM® Endpoint
Manager console.
Before you begin
You cannot modify templates using this procedure. Ensure that
the analysis
VMware Host
Overview is active. If you need to activate this analysis,
a warning message is displayed in the
VMware Modify
Virtual Machine Task. You
cannot proceed without activating the analysis. After you activate
the analysis, it can take a few minutes for the results to gather.
To
check the status of the analyses, from the navigation tree in the Server Automation domain,
click . Ensure that the Status changes
from Not Activated to Activated
Globally. In the Activate Analyses list,
click Host Overview. In the Analysis: VMware Host
Overview window, click the Results tab.
When the Results window is populated with one
or more computer names, the analysis is activated. If any of the computer
names displays the message "not reported", the analysis is not gathered.
For
non-English users: VMware vCenter supports
only Simplified Chinese, Japanese, German and French. You can use
this Task only
if the console language that you selected in Tivoli® Endpoint Manager console is
identical to the console language selected in VMware.
About this task
This Task is automatically
populated with data from VMware. To
work with other data, you need to turn off validation and enter your
own values into the parameter field. To override the data that is
provided in the form, check whether a button exists in the Validation column
to the left of the parameter that you want to disable and select OFF.
For more information, see Turning off validation in a Task.
Complete
the following steps to modify a virtual machine.
Procedure
- Open the Server Automation domain
- From the navigation tree in the Server Automation domain,
click . This opens the list of Host Configuration Tasks.
- From the Host Configuration list,
select VMware Modify
Virtual Machine.
- In the Task: VMware Modify
Virtual Machine window, from the Host list,
select the host on which the virtual machine that you want to modify
is running.
- From the Virtual Machine Name list,
select the name of the virtual machine that you want to modify. If
the virtual machine name that you want to modify is displayed more
than once in the Virtual Machine Name list,
you can verify that the virtual machine that you select is correct
by viewing the Virtual Machine UUID and the IP
Address field. If you want to modify a virtual machine
that does not display in the Virtual Machine Name list,
select OFF on the validation button for Virtual
Machine Name in the Validation column.
For example, if you want to modify a virtual machine that does not
exist, but is scheduled to be created, you can turn off validation
and enter the name of the virtual machine to be modified. You can
then schedule the Task to take
action when the virtual machine exists. If you disable validation
for Virtual Machine Name, the validation for
the Power State and Disk Size is
also disabled. The validation for Power State and Disk
Size is disabled because the IBM Endpoint
Manager console
cannot validate that the power state or disk size of a virtual machine
name that has been entered while validation is disabled. You must
ensure that the virtual machine name that you enter is correct or
the Task fails
in VMware.
- You can use the Power State field
to view whether the virtual machine that you want to work with is
powered on or off. VMware only
allows you to modify virtual machines that are powered off. However,
if you want to modify a virtual machine that is currently powered
on, but is scheduled to be powered off at a later stage, select OFF on
the validation button for Power State in the Validation column.
You can then schedule the Task to take
action when the virtual machine is powered off.
- From the Disk Name list, select
the disk that you want to modify. You can use the Maximum
Size field to view the maximum size that you can configure
a virtual machine.
- In the Maximum file Size field,
you can view the maximum file size that can be allocated to a virtual
machine that is created on the datastore. You cannot modify the disk
size of the virtual machine to be greater than the maximum file size
allowed for the datastore.
- In the Datastore free space field,
you can view the free space available on the datastore. You can add
the value that is displayed in the Datastore free space field
to the value that is displayed in the Disk Size field.
- In the Disk Size field, enter the
disk size that you want to allocate to your virtual machine. In VMware, you
can only increase the disk size, you cannot decrease it. You cannot
exceed the maximum file size configured for the datastore. You cannot
exceed the free space available on the datastore. If you want to enter
a value for the disk size that is greater than the size that is currently
available on the datastore, select OFF on the
validation button for the Disk Size in the Validation list.
For example, if you know that virtual machines on the datastore are
scheduled to be deleted and free disk capacity will become available,
you can enter a greater disk size than that which is currently available.
You can schedule the Task to take
action when more disk space becomes available. You must ensure that
this information is correct. You cannot modify a virtual machine with
a provisioned disk size greater than the Maximum file size for
the datastore even if you disable validation.
- From the Memory Size list, select
the memory size that you want to allocate to your virtual machine.
- In the Number of Virtual Processors list,
select the number of processors that you want to allocate to your
virtual machine. You must enter a number greater than zero.
- In the Take Action dialog box, ensure
that Specific computers selected in the list below is
selected and from the list of Computer Names,
select the host of the virtual machine that you want to modify and
click OK.
Results
When your virtual machine is modified, the
Status changes
to
Completed in the
Action: VMware Modify
Virtual Machine window.
