About volume types
Authorized infrastructure administrators use the CloudSystem Console to configure and manage
volume types. When configuring storage systems, the volume types define specific storage
characteristics.
How are volume types used?
When you configure your storage systems, you must attach a block storage driver to each volume
type. The volume types, in turn, help define the characteristics of the volumes that are created by
the cloud users.
Managing volume types
Before adding a volume type, the following storage conditions must exist:
• 3PAR F-Class, P7000 or P10000 storage system is installed in the environment.
• Sufficient space is available on the 3PAR storage system.
• HP 3PAR OS 3.1.2 MU2 is installed.
• IMC V4.4.0 is installed.
• Fibre Channel fabric support.
• REST API interface must be enabled on the 3PAR.
• One domain with one CPG is required.
• At least one block storage driver has been added.
Volume types added using the CloudSystem Console can be edited in the CloudSystem Console.
If you created a volume type outside of the console; for example, using the OpenStack Nova or
Cinder CLI, you cannot edit the volume type in the console.
Understanding volume types data
Volume types data provides details for each of the volume types you add.
