Migrating resources to and from a CLPR

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

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

When migrating resources to and from CLPRs, multiple parity groups that configure interleaved parity groups must be in the same CLPR.

Prerequisites

Required role: Storage Administrator (System Resource Management)
