Cache partitioning workflow
Calculate the cache capacity required for your needs taking into account other features and functions that also have cache capacity requirements. For details, see Calculating cache capacity.
If needed, work with your Hitachi representative to have additional cache memory installed in your storage system.
Determine an appropriate time to create CLPRs and migrate resources to the new CLPRs. Creating CLPRs and migrating resources can significantly degrade host performance and should be performed during the initial installation and setup of the storage system or during a maintenance window.
Create the new CLPRs and migrate resources to the new CLPRs. For details, see Creating a CLPR and Migrating resources to and from a CLPR.
Manage the CLPRs as needed.
After a CLPR has been created, you can change the CLPR name and CLPR cache capacity. For details, see Editing the settings of an existing CLPR.
