Creating a CLPR

Caution

Creating CLPRs can significantly degrade host performance and should be performed during the initial installation and setup of the storage system or during maintenance.

Before creating a CLPR, read Cautions and restrictions for Virtual Partition Manager.

If no CLPRs have been created, the entire cache is displayed as CLPR0. When you create the first CLPR, CLPR1 is added. The maximum number of CLPRs that you can create are listed below:

  • Maximum of 1 CLPR (CLPR1) for VSP G100, 9 CLPRs (CLPR1 to CLPR9) for VSP G200, 22 CLPRs (CLPR1 to CLPR22) for VSP G400, and 31 CLPRs (CLPR1 to CLPR31) for VSP G600 and VSP G800.

When you create a CLPR, you assign the necessary capacity from CLPR0 to the new CLPR. The default cache capacity is listed below

  • 4 GB

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. Click Create CLPRs to open the Create CLPRs window. CLPR ID displays the first available CLPR ID or a blank if no CLPR ID is available.

  3. In CLPR Name, enter the CLPR name (maximum 16 alphanumeric characters). Each CLPR name must be unique. You cannot use a CLPR name that is already reserved. If no CLPR ID is available, a blank is displayed.

  4. In Cache Size , select the cache capacity. If no CLPR ID is available, a blank is displayed.

    The default size is 4 GB, and you can select 4 GB or higher value in increments of 2 GB. The maximum available capacity (subtracted the total usage capacity of other CLPRs from the total capacity of the storage system) is displayed as the upper limit value.

  5. Click Add. The created CLPR is added to the Selected CLPRs table.

    To delete a CLPR from the Selected CLPRs table, select the CLPR and click Remove. To change the settings of an existing CLPR, select the CLPR and Change Settings to open the Change Settings window.

  6. Click Finish.

  7. Check the settings in the Confirm window, enter the task name in Task Name, and click Apply.

    The Tasks window opens if Go to tasks window for status is checked.

Next steps

After creation, a CLPR has no resources (parity groups). To migrate resources to the new CLPR, see Migrating resources to and from a CLPR.
