You can select volumes and migrate them immediately or on a schedule.

You must be a storage administrator to migrate volumes.

Note: Ops Center Administrator limits the number of volumes you can migrate at any one time to 300, because of the high load to the storage system and the long processing time.

For internal migration, ensure the following:

  • All selected volumes belong to a single storage system that is managed in Ops Center Administrator.
  • All selected volumes will either be migrated to a different pool within the same storage system or have the DRS settings changed while remaining in the same pool, which contains the source volumes within the storage system.
  • All selected volumes are attached to servers.
  • The volumes are not protected. However, a clone pair can be migrated if the P-VOL status is PSUS and the S-VOLs status is SSUS.
  • The storage system has at least one eligible pool (Thin or Tiered) with enough space to migrate volumes. If you want to change the DRS settings type using the same pool, which contains the source volumes within the storage system, make sure that there is enough space in that pool.

For external migration, ensure the following:

  • The target storage system must be onboarded in Ops Center Administrator.
  • The source volumes must be virtualized and selectable as external volumes.
  • The target storage system must have at least one eligible pool (Thin or Tiered) with enough space to migrate volumes.
  1. For internal migration, navigate to one of the following to select volumes:
    • The Volumes window
    • The details window for a volume
    • The details window for a server
    • The details window for a pool
  2. For external migration, navigate to the External Volumes window.
  3. Select volumes to migrate, then click Migrate volumes.
  4. Choose the type of Data Reduction Share Setting for the target volumes.
    Tip: If you select Auto, the same setting as the source volumes will be applied to the target volumes.
    Note: For VSP One Block, if you select Auto for external migration, Data Reduction Share Setting for the target volume will be Enable.

    If you want to change the DRS settings type, select Yes for Use the same pool containing the source volume.

    Note: You can select Yes for Use the same pool containing the source volume for the following storage systems:
    • VSP One Block with microcode version A3-03-01 or later.
    • VSP 5000 series with microcode version 90-09-25 or later.
    • VSP E series with microcode version 93-07-24 or later.

    Select a pool that has enough space to migrate the volume, then click Next.

  5. In Volume Settings, you can choose a type of Capacity Savings and select a Volume ID / Range. You can also set up cleanup tasks by selecting Shred Source Volumes and Delete Source Volumes.
    Tip: If you select Auto, the same setting as the source volumes will be applied to the target volumes. Otherwise, deduplication and compression will be set when the source volume has Capacity Saving disabled and Data Reduction Share Setting is selected as Enable.
    Note: For VSP One Block, if you select Auto for external migration, Capacity Saving setting for the target volume will be Deduplication and Compression.

    When you select these options, Ops Center Administrator shreds or deletes the source volumes after a successful migration

    The default selection for Volume ID / Range is Auto, which allows automatic selection. You can select either a Decimal or Hexadecimal range and enter the endpoints of the range.

    The default selection for Shred Source Volumes is No and the default selection for Delete Source Volumes is No.

    Click Next.
