Remove devices

Use this procedure to remove a storage or acceleration device.

Prerequisites

Before removing an NVDIMM acceleration device, remove all storage devices that are being accelerated by the NVDIMM. Then, remove the NVDIMM from its acceleration pool.

Steps

  1. On the menu bar, click Block > Devices.
  2. In the list of devices, find the device that you want to remove, make a note of the SDS in which it is installed, and the storage pool or acceleration pool to which it belongs.
    This information will be useful for adding the device back to the system later.
  3. Select the required device, and click More Actions > Remove.
  4. In the Remove Device dialog box, verify that you have selected the desired device, and click Remove.
  5. Verify that the operation has finished and was successful, and click Dismiss.
    A rebuild/rebalance occurs. For each device that was removed from the SDS, the corresponding cell in the Used Size column counts down to zero, and then the device disappears from the Devices list.
