Create volumes for a registered storage system so you can attach them to a server.

When you create volumes in Ops Center Administrator you can:

  • Create multiple volumes of the same size or different sizes at the same time.
  • Select the specific pool for volume creation or let Ops Center Administrator automatically select the best pool based on utilization.
  • Specify a common label and starting label suffix for identical volumes that are the same size and have the same pool requirement.
  • Set up compression, or deduplication and compression for the volume.
  • Create parity groups.
  • Create pools.
  • Add servers (optional).
  1. On the Ops Center Administrator dashboard, click Storage Systems to see the inventory of storage systems and capacity information.
  2. Click a storage system to see its configuration of servers, pools, ports, volumes, and parity groups.
  3. Click Volumes to see the inventory of configured volumes for the storage system.
  4. Click the plus sign (+) to open the Create Volumes window.

  5. Configure volumes for the specified storage system.
    1. To add the volume to a virtual storage machine, select one in the Virtual Storage Machine menu.
    2. Enter the volume label and select a suffix for it.
    3. Select the number of volumes.
    4. Select the size.
    5. Select the volume unit: MiB, GiB, TiB, or Blocks.
    6. For creating a DRS-VOL, select Enable from Data Reduction Share.
    7. Select the pool type: Tiered or Thin.
    8. For a Thin pool, select the Pool Tier.
      If the storage system has available capacity from external storage, you can also select the External tier.
    9. (Optional) Select the pool from the list of available pools. The default selection is Auto Selected, which means that Ops Center Administrator selects the best pool for provisioning the volume based on utilization and tier requirements.
      Note: DDM pools are not available and cannot be used to create volumes.
    10. You can select Compression, Deduplication and Compression, or No from the Capacity Saving drop down list.
      Note: You can set capacity saving for volumes based on tiered pools for the following storage systems:
      • VSP 5000 series
      • VSP G1x00, F1500 with microcode version 80-05-4x or later.
      Note: If you choose Deduplication and Compression and later want to update the volume to Compression you must first disable Capacity Saving.
    11. (Optional) Select a Volume / ID Range to specify one for the new volume for granular management of volumes. For instance, for ease of management, you can assign a certain range of IDs to certain departments in your organization. ID ranges can be specified in decimal or hexadecimal. The default selection is Auto, which means that Ops Center Administrator automatically selects the ID for the volume.
    12. (Optional) For a Tiered Pool, select the Tiering Policy from the list. Tiering policy choices available in the list depend on the choice of pool that was made in the previous step. Tiering policy choice is not available for auto-selected pools.
    13. For creating a T10PI-VOL, select Enable from T10PI.
      Note: To define an LU path between a port and an LDEV with the T10PI attribute enabled, the port must have T10PI mode enabled. To enable T10PI mode on the port, use another storage management tool.

      To achieve end-to-end data integrity from components of the server such as application, HBA, and so on to disk drives using T10PI or the combination of T10PI and DIX, see the storage system documentation to verify the supported version of the OS and HBA. To configure the required settings for your servers and HBAs, see the OS documentation.

    14. You can set the volumes as command devices by selecting Enable from the Command Device Setting drop down list.
  6. Click the plus sign to move the configured volume to the lower portion of the Create Volumes window.
    A blank row appears at the top of the window where you can create more volumes.
  7. Click Submit.
A job is started to create the volumes and add them to the volume inventory for the storage system.
  • Verify the status of the volume-creation job by clicking Jobs.
  • Attach volumes to a server.
