Removing a Cache or Log Device from an Existing Storage Pool (BUI)

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.

1. Go to Configuration > Storage.
2. From the Available Pools list, select an online pool from which to remove the device.
3. Click REMOVE.
4. Select the number of log and cache devices to be removed from the storage pool.

   ---

   Note -  If the log devices use a mirrored profile, a message reminds you to select an even number of log devices to remove. If they use a striped profile, you may remove an even or odd number of devices.

5. Click COMMIT.
