Manage the Lifecycle of VMware ESX Virtual Machines › Manage Your Reserved Machines › Modify VMware Reservation

Modify VMware Reservation

Your virtual machine requirements can change after your machine is available. You can increase or decrease the quantity of CPUs and amount of memory on the virtual machines you reserved. Your Service Provider sets the available configuration options. Additionally, configuration change requests are subject to approval by your service provider or administrator.

You can add, modify, or remove disks to the virtual machine when the storage requirement changes. You cannot reduce the disk size as it can delete the data in the disk. You can also change the secondary users who manage the reservation.

You can modify the attributes like CPU, Memory and so on of a reservation that starts on a future date.

You can schedule the change to the VMware virtual machine. To schedule a VM change, select the Schedule Change check box, and enter the expected date and time of the change. The CA Service Catalog processes the request at the specified time.

The following functionality is available if you are using CA Server Automation r12.8.1 or later version. They are not available in CA Server Automation r12.8 or earlier versions.

Reboot VM on Modify VMware

Sometimes for changes to VM to take effect a reboot is required. If a reboot is not required, then the changes are made in the VM immediately. When a reboot is required, the CA Service Catalog prompts the same and you can schedule the VM reboot without affecting the VM users.

The status request that needs reboot changes to Pending User Approval.

Do one of the following actions to complete the request:

• You can open the request from the Pending My Actions page and can click Approve VM Reboot to approve the change.

  The request status changes to Completed.

  The VM is reconfigured when it goes down for a reboot.

• You can open the request from the Pending My Actions page and can click Cancel to cancel the request.
