Configuring a migration on a RAIN system

To configure a data migration on a RAIN system:

  1. On the left side of the Migration page, click Configuration.

    The Configuration panel displays step 1 (one) of the migration configuration (Choose items for migration). The Select Hardware for Retirement section lists the storage nodes in the HCP system.

  2. Select the nodes from which you want to migrate the data.

    To clear your selections and start over, click Cancel.

  3. Click Next.

    The Configuration panel displays step two of the migration configuration (Review configuration summary and confirm). The Configuration Summary section in this panel indicates whether the migration configuration is acceptable.

    NoteWhen you click Next, HCP checks that the system is in a valid state to perform the migration. This includes checking for degraded RAID groups. This check can take up to 90 seconds.

    If the configuration is not acceptable, you can click view details in the Configuration Summary section to display the specific reasons why. You can also click Configuration Report to download the configuration summary and details to a file. The default name for this file is Configuration-Report.txt.

    The Configuration Details section in the step-two panel lists the nodes selected for migration:

    • To change the migration configuration, click Modify Configuration. The Configuration panel redisplays step 1, which shows your current selections.
    • To restart the migration configuration, click Cancel. The Configuration panel redisplays step 1 with all selections cleared.
  4. Optionally, add a description of the data migration and/or change the performance level for the Migration service:
    • To add a description:
      1. Click Add description.
      2. In the text box that opens, type a description of the migration. This text can be up to 1,024 characters long and can contain any valid UTF-8 characters, including white space.
    • To change the performance level, in the Performance Level field, select Low, Medium, or High. The higher the performance level, the greater the load on the HCP system.
  5. Click Start Migration.

    The Migration service begins preparing for the data migration, and the Migration page switches to the Overview panel.
