The following procedure describes the basic option for creating a parity group and enabling encryption.

Note: You cannot use Ops Center Administrator to create parity groups on the following storage systems.
  • VSP 5000 series
  • VSP G1x00, F1500
An authorized service representative must create these parity groups outside of Ops Center Administrator.
  • Register the storage system.
  • Identify the target storage system name.
  • Identify the total capacity that you expect to use. Plan to use all of the available disks in the system when you create parity groups.
  1. On the Ops Center Administrator dashboard, select the Storage Systems (Storage systems) icon in the resource side window to see the inventory of registered storage systems.
  2. Click a storage system to create and configure the parity groups for it.
  3. Click Parity Groups to see the inventory of all parity groups in the storage system.
  4. Click the plus sign (+) to open the Create Parity Groups window and review the list of unused disk types in the storage system. This information is grouped by disk type, disk speed, and disk capacity, and includes the following details:
    • Number of available disks.
    • Available spares detected for each disk type, disk speed, and capacity.
    • Number of new or additional spares to reserve. This calculation is the total spares needed based on best practices, and the number of existing spares in the system.
    • Correct RAID configuration for the disk type.
    • Number of parity groups that you can create.
    • Total usable capacity that is available based on the number of parity groups and the RAID configuration.

  5. Decide whether the RAID configuration for each disk type is acceptable. Choose one of the following options:
    • Accept the RAID configuration, which uses the full capacity of the installed drives.
    • Change the RAID configuration or create fewer parity groups. Ops Center Administrator shows the number of parity groups that you can create for the new RAID configuration and the corresponding usable capacity.
  6. (Optional) To use encryption, go to Encryption option and click ON.
    Prerequisites for enabling encryption:
    • Storage system must have an Encryption Disk Board.
    • Encryption License Key must be installed.
    • Key Management Server must be configured on the SVP.
    Note: You cannot disable Encryption in Ops Center Administrator.
  7. Click Submit.
A job is started to create the parity group for the storage system. This job includes the following tasks:
  • Identifies the appropriate number and position for the spare disk.
  • Assigns a spare disk.
  • Creates the required number of parity groups for the requested RAID layout.
  • Creates and quick formats the necessary volumes on the parity group so that it is ready for pool creation.
  • Creates sub-jobs when creating multiple parity groups. Each sub-job shows the status of the parity group creation.

Click the Monitoring tab and select Jobs in the side menu to verify the parity group creation status.

Note: Parity group creation might take a long time.
