REST API to expand a VMDK

The disk file of a virtual machine represents the storage volume of a virtual machine, and is suffixed with .vmdk.

For an OS disk, use this API:

/admin/resources/instances/<instance-uuid>

Note: This API applies to these aspects:

• Cloud Pak System Service
• Cloud Pak System Software
• Cloud Pak System System

The following example is related to this API.

PUT
{
   "disks": [
       {
           "id": "88b80eb3-fff6-447f-8247-183082f4d264",
           "size": 102400
       }
   ]
}

The size of an OS disk is calculated in MB. If there are more than one OS disks, include all of them even if you want to resize only one of them. OS disks cannot be removed. See the following implementation details.
