You can create and map snapshots by using the REST API to prepare volumes to use on other servers.

  • Identify the following:
    • Volume ID
    • Snapshot group name

      If you want to register snapshots to an existing snapshot group, specify the same snapshot group name. For details on how to use a snapshot group name to perform operations, see the Hitachi Thin Image Advanced User Guide.

    • Pool ID

      Specify the pool in which to store differential data.

      Note:

      Be sure to select a pool that has a sufficient amount of free space. If pool utilization exceeds the depletion threshold, creating snapshots might fail.

  • You must have the Storage Administrator (Local Copy) role.
Use the REST API to create and map a snapshot. Specify Mapped Snapshot as the snapshot type.
Request line
POST base-URL/simple/v1/objects/snapshots

For details on the API, see the REST API Reference for VSP One Block Administrator .

The newly created snapshots and the associated volume IDs are displayed in the snapshot inventory.

Volume names in the following format are automatically assigned to the newly created volumes: "Snapshot of ID: ID-of-volume-created-from-snapshot".
