"Add Hardware" panel -> select "Hard Disk", click "Next" -> select "Create a new virtual disk" (by default), click "Next" -> select "Disk Size" to 8GB, click "Next" -> select "Virtual Device Node SCSI(0:1)" (by default), click "Next" -> click "Finish"
- click "OK" on "Virtual Machine Properties" panel
- vSphere Client -> virtual machine “Summary” tab -> "Refresh Storage Usage"
- reboot virtual machine
