Use the following task to remove a read cache or log device from an existing storage pool. This capability is useful when preparing for a system update that requires the removal of certain cache devices.
If a pool has cache devices on both controllers of a clustered configuration, you must perform this procedure on each controller.
To add a device to a different, existing storage pool, see Adding a Cache, Meta, or Log Device to an Existing Storage Pool (BUI).
Before You Begin
Do not perform a pool configuration operation while a disk firmware upgrade is occurring. To check if an upgrade is in progress, navigate to Maintenance > System.
