Removing PCIeSSDs From Fluid Cache Pool

To remove a PCIeSSD from a cache pool:
  1. In the Server Administrator window, under the system tree, expand Storage to display the controller objects.

  2. Expand the PCIe SSD SubSystem object.

  3. Expand the Enclosure (Backplane) object.

  4. Expand the Physical Devices object.

    The Physical devices on PCIe SSD SubSystem page is displayed with the available list of physical disks.
  5. From the list of Tasks corresponding to the physical disk to which you want to remove the PCIeSSD, select the Remove from Cache Pool option.

  6. Click Execute to remove the PCIeSSD. The following message is displayed:

    Device will be removed from Fluid Cache Pool. Are you sure you want to proceed?
  7. Click OK.

    Once the device removal is initiated from the cache pool, any dirty data is moved to the back-end disk. While the data migration is in progress, Storage Management displays a transient removal state. After the device is removed from the cache pool, the Part of Cache Pool attribute is Not Enabled.

    When the last but one PCIeSSD is removed from the Fluid Cache pool, the cache pool high availability changes from True to False indicating that the cache pool is Write Through capable only and the operational cache mode for any Fluid Cache disk configured for Write Back changes to Write Through.

    When the last PCIeSSD is removed from the Fluid Cache pool, the operational cache mode for all Fluid Cache disk changes to Pass Through.
