You can add a virtual hard disk to a virtual machine.

Prerequisites

If the virtual machine uses fast provisioning, power off the virtual machine. Non-fast-provisioned virtual machines support adding virtual machine hard disks while the virtual machine is running.

Procedure

  1. Click My Cloud.
  2. In the left pane, click VMs.
  3. Select a virtual machine, right-click, and select Properties.
  4. Click the Hardware tab and click Add in the Hard Disks section.
  5. Select the disk size, bus type, bus number, and unit number and click OK.
  6. (Optional) : Choose a storage policy for the hard disk.

    By default, all the hard disks attached to a virtual machine use the storage policy specified for the virtual machine. You can override this default for any of these disks when you create a virtual machine or modify its properties. The Size field for each hard disk includes a drop-down menu that lists all the storage policies available to this virtual machine.

    Important:

    You cannot override the default storage policy for any hard disk of a virtual machine that is deployed in a VDC where fast provisioning is enabled.

    If the storage policy supports IOPS allocation, a Disk IOPS field is displayed. You can accept the default value shown in this field or specify a desired level of disk I/O performance in the range 200-4000. For more information about IOPS, see the vCloud Director Administrator's Guide.

What to do next

Use the guest operating system tools to partition and format the new disk.
