Migrating resources to and from a CLPR

CautionMigrating resources to and from a CLPR can significantly degrade host performance and should be performed during the initial installation and setup of the storage system or during maintenance.

After creating a CLPR, you can migrate resources (parity groups) from existing CLPRs to the new CLPR.

When migrating resources to and from a CLPR:

  • Multiple parity groups that configure interleaved parity groups must be in the same CLPR.

Before you begin

  • Required role: Storage Administrator (System Resource Management)

Procedure

  1. Open the Cache Partitions window.

    1. On the Administration tree, click Cache Partitions.

    2. Click the Cache Partitions tab.

  2. On the Cache Partitions tab, click Migrate CLPR Resources to open the Migrate CLPR Resources window.

  3. In the Available Parity Groups table or Available Virtual Volumes table, select the resource that you want to migrate.

  4. Select the migration destination CLPR in the CLPRs table.

  5. Click Set.

    The resource selected in the Available Parity Groups table or the Available Virtual Volumes table is migrated to the CLPR selected in the CLPRs table. To check the information of the CLPR, select the CLPR and click Detail to open the CLPR Properties window.

  6. When you are done adding resources to migrate, click Finish.
