Modify rank — Select extent pool

Use this page to modify an extent pool for the rank.

Introduction

The Modify option is available in the Select Action drop-down list only if the number of extents used on the rank is 0.

You can add a rank to an extent pool at any time if the status of the rank is unassigned. In a simulated reconfiguration mode or in a real-time configuration, you can remove a rank from an extent pool only if no extents are used on that rank; otherwise, the rank can be removed from the extent pool in a configuration for a new or fully deconfigured storage unit. You can change extent pools for this rank only if the modification is done on a new or fully deconfigured storage unit.
